Easy Vanilla Layer Cake

This vanilla cake can also easily be adapted for all types of flavors. A few of my favorites are my Strawberry Mascarpone Cake and this Cookies and Cream Cake

Everyone needs their go-to, easy vanilla cake, especially if you’re making a layer cake. This cake is dense but spongy and very stable for stacking the layers. It can be paired with just about any flavor of frosting, but my favorite it my vanilla buttercream frosting

This is one of the easiest cakes to make because it’s an oil-based cake recipe, so there’s no waiting around for the butter to soften or worrying about properly creaming the butter and sugar together. The oil also creates a more tender and fluffy crumb as well.  The texture is denser more so than it is light and airy, but it’s super moist and fluffy. It’s also very sturdy which makes it a great option for a layer cake.

Let’s dive into the the process for how to make and decorate this cake, plus I’m sharing my secrets for the fluffiest vanilla buttercream!

RECIPE INGREDIENTS

  • Granulated sugar: The ratio of sugar to flour is very important in baked goods, so be sure to follow the recipe. Some people have reduced the sugar without an issue but I don’t recommend it.
  • Vegetable oil: Oil makes these cupcakes more moist than a recipe with butter.
  • Whole eggs: This is a dense and spongy cupcake, so we’re using the whole egg. 
  • Pure vanilla extract: Be sure you get a high-quality REAL vanilla extract for this recipe because the vanilla is your main ingredient for flavor. 
  • Sour cream: Sour cream helps keeps this cake very moist.
  • All-purpose flour: This is not interchangeable with cake flour. So be sure to use all-purpose for this recipe. 
  • Baking powder & Salt
  • Milk:  I use nonfat because that’s what I keep in my fridge, but you can use any type of milk you have on hand.

INGREDIENT SUBSTITUTIONS

  • Sour cream: This is essential for keeping the cake moist. If you don’t have sour cream. I recommend substituting with non-fat Greek yogurt. The recipe calls for light sour cream, but you can also use full-fat sour cream. If you need to, you can omit it completely, but note the cake will not be nearly as moist.
  • Butter instead of oil: You can use 1/2 cup of melted butter instead of oil, but personally I don’t think it’s as good. You can also use coconut oil instead of vegetable oil. 
  • Gluten-free flour: I have tested this recipe with a one for one measure gluten-free flour and it worked out great

HOW TO MAKE A VANILLA CAKE

  1. Preheat the oven to 350°F.
  2. Beat together the sugar, vegetable oil, eggs and vanilla extract until well incorporated.
  3. Next mix in the sour cream and beat until well combined.

  4. In a separate bowl combine the remaining dry ingredients: flour, baking powder and salt. Add half the dry ingredients, and beat on low speed while pouring in half of the milk and mix just until the flour starts to incorporate.
  5. Finally add the remaining dry ingredients, and the remaining milk. Beat on low speed until all of the ingredients are well combined.

  6. Pour the batter into three 8-inch baking pans (affiliate link) and bake at 350°F for 20-23 minutes. Cool completely before frosting.

How to prepare the pans for a layer cake

Grease and flour your pans: generously grease and flouring the pans to prevent the cake from sticking. I prefer using Crisco vegetable spread as opposed to cooking spray, but if you only have cookie spray, definitely use that. 

Line the pans: lining the pans with parchment paper or a round silicone baking mats (affiliate link) will ensure there’s the cakes don’t stick to bottom of the pans, and it makes it much easier to get the cakes out of the pans.

Bake Even stripes: I love using bake even stripes (affiliate link) because it helps to bake the layers flatter. Without them, the edges of the cake bake quicker, forcing the centers to bake last, and therefore doming in the middle. You’ll notice the outside edges of the cake are also a little darker without them. The bake even stripes should be WET when apply them to the outside edge of the pan.

Other pan sizes

This recipe has been used for several other size pans without adapting the cake recipe- you just may need to scale the frosting recipe accordingly.

  • For two 9-inch cakes, they baked from 28-32 minutes. Baking times will vary due to how full the pans are, type of pans and true oven temperature. Please note these did “crust” a little more on the outside edge due to extended baking times and they rose quite a bite in the middle, so you’ll lose more of the “dome” of the cake.
  • For two 8-inch pans: divide the batter evenly, about 2 1/2 cups per each pan. Bake for 28-32 minutes.
  • For 6-inch pans: a full recipe will make four 6-inch layers, filling each one with about 1 1/3 cup of batter and baking for approximately 24-30 minutes. You can halve the recipe for a small, 2 layer cake. 
  • For 10 inch pans: I’ve never tested this with 10 inch pans, but I would recommend making 2 layers so you still have nice, thick cake. Trying baking for 15-20 minutes and assessing if additional time needed. 

My secrets for the best vanilla buttercream

My secrets to making the perfect vanilla buttercream for frosting cakes is starting with COLD butter.  This allows you to control the consistency of your frosting, and prevents the butter from getting too soft when decorating or coloring the frosting. Plus, there’s no waiting around for your butter to soften prior to starting, so that’s a huge bonus.

However, since the butter is cold it requires beating the frosting for quite a bit of time. So before you even start adding powdered sugar, spend 5-7 minutes beating the butter to a whipped consistency. As you add the powdered sugar, spend a few extra minutes beating it at each stage. This is key to making the best whipped, silky texture.

You want to be sure the frosting is not too stiff, or it will be more difficult to actually frost the cake. If you think the frosting is too stiff, you can add additional heavy whipping cream (or milk), 1 tablespoon at a time, and beat for a few more minutes.

For this cake you’ll need quite a bit of frosting. Besides the filling in between the layers, you’ll need extra frosting for decorating. Since this recipe requires so much butter, you might consider making only a half batch at a time if you’re using a standard 5-quart mixer. I have both a 5 and a 6-quart mixer, and I use my 6-quart mixer when I’m making this frosting. It’s a much larger capacity.

How to decorate this Vanilla Layer cake

I love this cake because I pushed myself out of my comfort zone. I am not a cake decorator in the traditional sense. Of course, I’ve had a lot of practice over the years, but when it comes to cakes, I so often tend to stick with my go-to large open star piping tip. However, for this cake, I wanted to do something different but still easy.

This is a super approachable way to decorate a cake. I never thought I was very good at piping roses, but you guys, it’s SO SO easy! Here are some of the tools I used. 

  • 1M piping tip (affiliate link):  If you’re not fully comfortable, try piping a few of them on some clean parchment paper, and then you can reuse the frosting. Start by piping your roses, and then fill in the open spaces with the stars and rosettes.
  • Open star tips: Size 18(affiliate link), Size 21(affiliate link), can be used to create a variety of shapes and rosettes

If you use your piping bags with couplers (affiliate link), you can easily switch out the tips with the different frosting colors. These can be purchased at stores like JoAnn Fabrics, Michael’s, a cake supply store, or online. 

For more helpful decorating tutorials see my posts for How to Use a Piping bag and How to decorate with piping tips

To color the frosting

You can use either the Wilton Color Right Food Gels (affiliate link) or AmeriColor Gels (affiliate link). I think the AmeriColor gels because they offer a wide variety of colors and you can purchase them as single either online or at a cake supply store.

The best way to dye your frosting if you’re looking for different shades is to start with a half a drop in one bowl and then get progressively darker. Just remember that you only need a TINY bit of this gel to color these small amounts of frosting. It’s helpful to use a toothpick to add small amounts to your bowls at a time. 

Here’s what you need:

  • 1 cup of frosting for the roses (AmeriColor teal)
  • ½ cup for the darker blue color
  • ¼ cup of the white, undyed frosting

How to store a frosted cake

The best option is to use a cake carrier which can allow it to be stored in an airtight container. This locks in the moisture. You can also slice it and store it in a tupper ware container. 

You do not have the refrigerate this cake unless you live in a hot a humid environment. Since the frosting is made with butter, it is subject to melting in the heat. If you need to refrigerate the cake, try to do so in airtight container. If it’s already sliced, then I recommend placing plastic wrap up against the sliced edge to help prevent it from drying out. It’s best to serve at room temperature, so remove the cake in plenty of time prior to serving. 

Freezing this cake

I normally don’t freeze a decorated cake. Instead, I’d recommend freezing the layers and frosting in advance, and then thawing and decorating when ready. Place a piece of parchment paper on the top and bottom of the cake layer, double wrap the cooled layers in plastic wrap. Freeze the frosting in a freezer-safe, air-tight container. Thaw to room temperature and rewhip prior to frosting the cake.

Moist Vanilla Layer Cake

  • Author: Beyond Frosting
  • Prep Time: 90 minutes
  • Cook Time: 30 minutes
  • Total Time: 2 hours
  • Yield: 10-12 slices

Description

This is the perfect Vanilla Cake Recipe! Thick layers of vanilla cake and  my favorite vanilla frosting. It’s an easy recipe to make using oil instead of butter which makes it super moist and spongy.

Ingredients

For the cake:

  • 2 cups (380g) granulated sugar
  • ½ cup (118 ml) vegetable oil
  • 3 large eggs
  • 1 tablespoon (14.8 ml) pure vanilla extract
  • ½ cup (118 ml) light sour cream
  • 2 ½ cups (350 g) all-purpose flour
  • 3 teaspoons (11.2 g) baking powder
  • 1 teaspoon (5 g) salt
  • 1 ¼ cups (296 ml) milk (I use nonfat)

For the frosting:

  •  2 cups (453g) unsalted butter, cold
  • 78 cups (910-1041g) powdered sugar
  • 1 tablespoon (15ml) vanilla extract
  • 23 tablespoons (30-44ml) heavy whipping cream (or milk)
  • Pinch of salt

Instructions

  1. For the cake: Preheat the oven to 350°F. Prepare three 8-inch round baking pans (affiliate link), line the bottom with parchment paper and grease the sides. Prepare with bake even strips (affiliate link).
  2. In a large mixing bowl, combine the sugar, vegetable oil, eggs and vanilla extract. Beat on medium speed until the eggs and oil are well incorporated and the batter is lighter in color, about 2 minutes. Scrape down the bowl as needed.
  3. Next mix in the sour cream and beat until well combined.
  4. Combine the dry ingredients in a separate bowl. Add half the dry ingredients, and half the milk, beat on low speed just until the flour starts to incorporate.
  5. Finally add the remaining dry ingredients and milk, mixing on low speed until all of the ingredients are well combined. Use a spatula to scrape down the sides of the bowl and stir the batter from the bottom to the top to ensure it’s well mixed.
  6. Divide the batter evenly between the three pan, about 1 2/3 cups of batter per pan. Bake at 350°F for 20-23 minutes. Rotate your pans in the oven halfway through baking.
  7. Test the cake for doneness by inserting a toothpick into the center of the cake. If the toothpick comes out clean, you cake is done. Remove from the oven and allow to cool completely.
  8. For the frosting: Cut butter into pieces. Using the paddle attachment, whip the butter for 5-7 minutes, scraping down the bowl occasionally. Beat until the butter looks light in color.
  9. Alternate adding 2 cups of powdered sugar at a time with the liquid ingredients: vanilla extract & heavy cream. Ensure the powdered sugar is well combined, then and whip for 1-2 minutes before adding more powdered sugar.
  10. Once all the powdered sugar has been added, increase speed to medium-high and beat for another 3-5 minutes to whip additional air into the frosting.
  11. To assemble the cake, use a cake leveler (affiliate link) to cut the domes off the top of the cake. Place a dollop of frosting on your cake board and place the bottom layer of cake on top of that.
  12. Place about 2 cups of frosting in a large piping bag (affiliate link) fitted with a large open round tip, or simply cut off the end of the piping bag. Pipe a layer of frosting on top of the cake, starting at the outside edge and working your way into the middle. Spread evenly with an offset spatula. Repeat with the second layer of cake and then place your third layer on top.
  13. Use your piping bag to fill in any gaps between your layers and to create a crumb coat. Using an offset spatula (affiliate link) or icing smoother, wipe away the excess frosting, leaving you just enough to coat the outside of the cake. Do not mix your crumb coating frosting back into your icing if it has cake debris in it.
  14. Proceed to frost the top and sides of the cake using your offset spatula. Once the sides of the cake are covered, use you icing smoother (affiliate link) to remove any excess frosting.
  15. To decorate this cake: Use your hands to press the sprinkles into the sides of the cake. It’s best to do this over a sheet pan lined with parchment paper, allowing you to easily capture and reuse the sprinkles that fall off the cake.
  16. Take your leftover frosting and separate into 3 bowls: 1 cup, ½ cup and ¼ cup of white frosting (undyed).  Dye 2 bowls with you desired color, and leave 1/4 cup of frosting uncolored.
  17. In a small piping bag, use a 1M piping tip to pipe the large roses on top of your cake.
  18. Place the other frosting in two small piping bags (affiliate link),  fitted with a coupler and size 18 (affiliate link) or size 21 tips (affiliate link), fill with your other color and the white frosting. Fill in the negative space with a mix of stars and small rosettes.
  19. Keep this cake covered in an airtight cake container. Serve within 3 days for best results.

Notes

  • Depending on how much you fill the middle of your cake, you might need another half or quarter recipe of frosting to do your decorations, especially if you’d like to do more of a traditionally decorated cake with rosettes or something on top.
  • Baking pans:
    • For two 9-inch cakes, they baked from 28-32 minutes. Baking times will vary due to how full the pans are, type of pans and true oven temperature. Please note these did “crust” a little more on the outside edge due to extended baking times and they rose quite a bite in the middle, so you’ll lose more of the “dome” of the cake.
    • For two 8-inch pans: divide the batter evenly, about 2 1/2 cups per each pan. Bake for 28-32 minutes.
    • For 6-inch pans: a full recipe will make four 6-inch layers, filling each one with about 1 1/3 cup of batter and baking for approximately 24-30 minutes.
    • For 10 inch pans: I’ve never tested this with 10 inch pans, but I would recommend a 2 layer cake so you still have nice, thick layers. Trying baking for 18-20 minutes and assessing additional time needed from there.
  • Sour cream substitute: Sour cream helps keeps these cupcakes very moist, I do not recommend omitting it. Substitute with with non-fat Greek Yogurt if you do not have sour cream. Full-fat sour cream is also workable, but I prefer low-fat or fat-free.
  • Milk: Any type of milk can be used (full, reduced or low-fat)
  • Oil substitutes: I have tested substituting 1/2 cup melted butter in place of the oil. The cake still bakes just fine but I prefer the texture of the cake make with oil,
  • To make this as a single layer, please see my other vanilla cake recipe.
  • Storage and make ahead: The best option is to use a cake carrier which can allow it to be stored in an airtight container. This locks in the moisture. You can also slice it and store it in a tupper ware container. You do not have the refrigerate this cake unless you live in a hot a humid environment. Since the frosting is made with butter, it is subject to melting in the heat. If you need to refrigerate the cake, try to do so in airtight container. This is best served at room temperature.
  • Freezing instructions: I recommend freezing the cake layer if needed. Line the top and bottom with parchment paper, double wrap in plastic wrap and store in the freeze. Thaw completely before frosting.

    Would the result be good if I decreased the sugar somewhat? We don’t like it overly sweet. How much could I decrease the sugar by without compromising the texture, moisture of the cake?
    Also, how about buttermilk instead of sour cream? Would that work well?

    1. Beyond Frosting

      Hi Jody- I recommend baking the recipe as it. Any variation of the ingredients will not produce the same results, it will compromise the texture and moisture. Some people have reduced the sugar by 1/2 cup and been happy with it. I have not baked it this way myself. The best substitute for sour cream or plain or Greek yogurt.

  2. Tammy

    I doubled this cake recipe and was able to make 3 layers of 8 inch cakes (at your recommended 2.5 cups batter) AND 3 layers of 6 inch cakes. Very excited they rose beautifully and cooked between 25-35 minutes.
