Readers swear by this recipe and they are shocked when they hear my secret to making the perfect buttercream is that I use cold butter. Read on to find out why.

What is Buttercream Frosting?

Butter cream frosting is made using a combination of butter and powdered sugar, this is often referred to as American buttercream and it used for frosting cakes and cupcakes. It’s usually flavored with vanilla or other flavors of extracts.

Different Types of Buttercream Frosting

There are three main types of buttercream frosting:

  • American Buttercream Frosting – This is a simple and fast buttercream that’s essentially fat (butter, margarine, shortening), confectioners sugar and vanilla extract whipped together. This is the kind of frosting we will be making in this post.
  • Swiss meringue buttercream: is much less sweet than traditional buttercream. . This method heats egg white and sugar together. 
  • Italian Buttercream – This type of frosting is made by adding simple syrup to egg whites and whipping them until they form stiff peaks. The heat from the simple syrup cooks the white.

What You’ll Need

  • Unsalted butter: This allows you to control how much salt you want to add to the frosting. This is especially important when making large batches. You can use salted butter but the taste is not the same and I don’t recommend adding any additional salt.
  • Powdered (confectionary) sugar: My general rule of thumb is for every ½ cup of butter, I use 2 cups powdered sugar.
  • Pure vanilla (or another flavor) extract: The better the vanilla, the better the taste. I use a generous amount of vanilla extract.
  • Heavy whipping cream: Is used to make the frosting light and fluffy, and cut down the sweetness. If you don’t have heavy cream, you can use any type of milk.
  • A pinch of salt is optional and used to help control sweetness

How Much Powdered Sugar Do I Need?

The rule of thumb for most of my frosting recipe is that you should use 2 cups of powdered sugar for every stick of butter (1/2 cup). If you need to make your frosting stiffer or thinner, you can find the answers to those questions below.

How to Make Buttercream Frosting

What makes my recipe different is the fact that I start with cold butter. It sounds weird at first given that most recipes on the interest call for room temperature butter, but just trust me. Starting with cold butter allows you control the stiffness of the buttercream. 

  • Whip the butter: Cut the cold butter into 1 tablespoon size pieces and then whip it using the paddle attachment for 3-5 minutes, scraping down the bowl occasionally until it’s super light and fluffy. The additional mixing time is softening the butter.

  • Add Powdered (confectioners) sugar: Add the powdered sugar 2 cups at a time until it’s all be added. Each time I add powdered sugar, I be sure to whip the buttercream until it’s nice and fluffy again before adding more.

  • Add liquid ingredients (vanilla and heavy cream): As you start to add more powdered sugar, your frosting will become much thicker. This is when you need to start alternating in your wet ingredients such as extracts and milk or heavy cream, add as needed.
  • Add a pinch of salt (optional): You can add a pinch of salt to help cut the sweetness. Add slowly, as too much salt cannot be fixed. If you happen be using salted butter, then you may not want to add more salt.
  • Whip the frosting: Once all the ingredients are added, whip the frosting with the paddle attachment for another few minutes to get it nice and fluffy.

Can I Add Chocolate?

Now that we’ve covered the basics of how to make homemade buttercream frosting, let’s explore some ways to add chocolate! I have several chocolate frosting recipes on my site including my 2 basic recipes, each recipe goes into further detail about how it’s made. 

  • The Best Chocolate Frosting– a traditional American buttercream with powdered sugar and cocoa powder with a more whipped consistency.
  • Chocolate Fudge Frosting– an American buttercream with melted chocolate, cocoa powder and powdered sugar. A more intense chocolate flavor with a stiff consistency.

Ways to Use Your Frosting

There are so many things you can do with a good buttercream frosting. Putting it on cupcakes and cakes is, of course, a classic. But you can also put buttercream inside your cupcakes, or use it as a filling for sandwich cookies. I have even seen people hollow out fruits like strawberries and fill them with buttercream frosting for a simple and elegant dessert.

How many cupcakes can I frost with this recipe? Will it cover an entire cake?

This buttercream frosting recipe includes variations that will allow you to make enough frosting for 12 cupcakes, 24 cupcakes or a 3-layer 8-inch cake.

Can buttercream be made in advance?

This recipe can be made in advance and kept in an airtight container or in the fridge for two days before serving. Any longer than that and I would recommend freezing it.

Prior to using, you’ll need to allow it to soften to room temperature for a couple of hours and you may even want to rewhip it. If you’re planning to freeze it, you’ll need to do the same thing.

Your frosting is best for piping when it’s fresh. The longer it sits, the frosting will lose some of the air that you whipped into it. Therefore, it will be stiffer and harder to work with, which is is why I recommend you always rewhip it for a few minutes prior to use. 

How do you make stiff buttercream icing for cupcakes?

You can control how stiff or how thin you make your buttercream.  Add additional powdered sugar, 1/2 cup at a time to make your buttercream thicker. However, you want to be sure it’s no too stiff. 

Stiff frosting can be difficult for piping cupcakes. Also, as you continue adding powdered sugar, the frosting will be sweeter. You can use a liquid like milk or heavy whipping cream to thin out your buttercream, adding 1-2 teaspoons at a time as needed. 

However, you can still have a stiff whipped buttercream that is perfect for piping. Keep on mixing it, the longer you whip the buttercream, the lighter and airier it will be.

How do you make light, fluffy buttercream frosting?

The key to making fluffy buttercream is by whipping your frosting, a lot. If you follow my method for starting with cold butter and whipping it through the various stages, you should get a nice, fluffy frosting.

  • Whip the butter for a good 3-5 minutes before adding any liquid or powdered sugar. The butter will grow in volume and look very light in color.
  • Whip the buttercream for 1-2 minutes at a time after adding each cup of powdered sugar and again at the end for a couple of minutes.
  • I also recommend using heavy whipping cream. The heavy cream not only cuts the sweetness, but it adds to the whipped texture of the frosting.

Can I make buttercream frosting with a handheld mixer?

The short answer is yes, anything is possible. However, it will be difficult for you to make large batches of frosting, simply because the powder of a handheld mixer is not the same as a stand mixer.

I usually recommend slightly softening the butter if you plan to use a handheld mixer. You will likely need to spend even more time whipping the butter both in the beginning and throughout when adding the powdered sugar in order to achieve the same consistency.

  • How to Color Buttercream Frosting: Follow these step-by-step instructions to dye your buttercream different colors. I always recommend using gel colors as opposed to traditional food coloring. The gels are much more concentrated and therefore they do not thin out your frosting the way traditional food coloring does. You have several options for gel colors including the Wilton Recipe Right color system and Americolor which are my two favorite.
