Easy Banana Pudding Poke Cake with Cake Mix

I think at this point we’ve established just how much I love poke cakes. And for good reason! Not only are they so easy to make, but they taste so decadent and delicious and can be made with so many different flavors.

Recently, I’ve become obsessed with any banana-flavored dessert. I started with a Copycat Magnolia Bakery Banana Pudding and No-Bake Banana Pudding Cheesecake and now I’ve added to my list of banana desserts with this Easy Banana Pudding Poke Cake.

This is definitely a dessert I’ll be making time and time again. It’s a simple cake mix recipe made better with mashed banana, brown sugar, and buttermilk.

The brown sugar adds a warm sweetness while the buttermilk creates the ultimate moist and tender texture. This cake is filled with vanilla pudding, then layered with sliced banana, whip, and plenty of crushed Nilla wafers.

Poke Cake Ingredients

Here are a few things to keep in mind before you start on your poke cake recipe. Scroll to the recipe card below for the full list of ingredients and amounts! Skip the ingredients listed on the box and follow the recipe provided.

  • Vanilla Cake Mix – I like to keep the recipe super simple with a cake mix. If you want to make it entirely from scratch, use my Easy Vanilla Cake recipe.
  • Brown Sugar – I use light brown sugar, but whatever you have on hand will work.
  • Buttermilk – If you have buttermilk already, use that. Otherwise, you can check out my homemade buttermilk substitute using regular milk and lemon juice or vinegar.
  • Oil & Eggs
  • Pure Vanilla Extract
  • Bananas – The riper, the better. Bananas with any green on them won’t be nearly as sweet!
  • Instant Vanilla Pudding -Or, if you like an even more intense banana flavor, you can use instant banana pudding for the filling. I prefer vanilla so the cake and toppings and cake stand out more.
  • Cool Whip – You can also use homemade whipped cream if preferred.

How to Make Banana Pudding Poke Cake

This pudding poke cake takes next to no time to prep! Here’s a quick summary of the recipe:

  1. Make the cake: In a bowl, mix cake mix, brown sugar, buttermilk, oil, eggs, and vanilla. Beat until blended, then add the mashed bananas and mix until incorporated. Pour into a 9×13″ baking dish, then bake until set. Cool for 20 minutes.
  2. Poke the holes: Using the handle end of a wooden spoon, poke holes all over the top of your cake. Make them deep enough to add the filling, but not too deep.
  3. Add the filling: In a bowl, mix vanilla pudding mix and milk. Immediately pour the liquid mixture over the cake, then spread evenly to get the filling into the holes. Place into the fridge until cooled.
  4. Top and serve: Lay sliced bananas over the top of the cake, cover with Cool Whip, then top with crushed Nilla Wafers.

Tips and Tricks

  • Mash the bananas well. You’re more than welcome to leave a few bigger pieces if you like a little texture in your cake, but I definitely prefer the banana to be fully mashed.
  • How to tell the cake is done. To make sure your cake is cooked all the way through, insert a toothpick into the very center. If it comes out clean, it’s good to go. If there are still moist crumbs on the toothpick, it needs a few more minutes. This cake is quite dense.
  • Cool slightly before poking. I recommend letting the cake cool for about 20 minutes before you poke the holes. You want it to still be warm, but if it’s too hot you’ll end up with a mess.
  • Make ahead of time. The best part about poke cakes is they really just get better as they sit and all those flavors meld together. I recommend making yours the day before you plan to serve it! You can always add the fresh bananas and Cool Whip before serving to maintain freshness.

How to Store Finished Pudding Poke Cake

A fully assembled poke cake must be stored in the refrigerator so everything stays nice and fresh. It will last in an airtight container for 3-5 days, but the bananas are freshest in the first day or two.

  • ½ cup (110g) light brown sugar
  • 1 cup (236ml) buttermilk
  • ½ cup (118ml) vegetable oil
  • 3 large eggs
  • 1 teaspoon (5ml) vanilla extract
  • 2 medium bananas, smashed

For the Toppings:

For the Cake:

  1. Preheat the oven to 350° F.
  2. In a medium-sized bowl, combine cake mix, brown sugar, buttermilk, vegetable oil, eggs & vanilla extract. Beat on medium–high speed until all ingredients are well blended. Add the smashed bananas and continuing mixing until the bananas are well incorporated. Use a spatula to mix the batter from the bottom of the bowl to the top to ensure it’s well mixed.
  3. Pour the batter into a 9-inch by 13-inch pan and bake at 350°F for 28 to 32 minutes until the cake is set. Test the cake by inserting a toothpick into the center. If the toothpick comes out clean, the cake is done. Allow the cake to cool for 20 minutes.

For the Filling:

  1. While the cake is still warm, take the end of a wooden spoon or another round object and poke holes all over the top of your cake.
  2. In a medium-sized bowl, combine the vanilla pudding mix and the milk and whisk just until the liquid starts to dissolve. Immediately pour the pudding mix over the top of the cake and try to spread it evenly. Put the whole cake in the refrigerator until it is completely cooled.
  3. Prior to serving, slice the bananas and lay across the top of the cake and cover Cool Whip.
  4. Take a few Nilla Wafers and crush them in your hands to sprinkle over the top.
