Ingredient Notes:

Now let’s talk a little about just some of the ingredients that are in this strawberry banana cake. (The printable list of all ingredients are in the recipe card below.)

Bananas: For this recipe, you’ll need three, medium-sized very ripe bananas. If you use very ripe bananas, they’ll give you a stronger banana flavor.

Strawberry cake mix: This will be the base of the recipe and why it’s so easy to make. You’ll get the strawberry taste without having to use actual strawberries.

Milk & eggs: You’ll also add in these two ingredients instead of what the cake mix box calls for.

Cream cheese, butter and confectioner’s sugar: These ingredients will be used to make the cream cheese frosting. Adding homemade frosting to this cake is what really takes it over the top and gives it that ‘from scratch’ flavor.

Instructions

For the cake:

  • Preheat oven to 350 degrees F. Grease or spray two, 8 inch round cake pans.
  • In a large bowl, mash up the bananas, then add in all the other cake ingredients and mix on medium to medium-high speed unti well mixed.
  • Spread the batter evenly into the prepared pans and bake for approximately 25-30 minutes. Cake is fully baked when a toothpick inserted into the center comes out with a few moist crumbs on it or clean, but no raw batter.
  • Once baked, set the warm cake layers, still in the pans, onto a cooling rack to cool for about 10 minutes, then turn the cakes out of the pans and onto the cooling racks to cool completely before adding the frosting.

For the frosting: (for an even easier frosting option, see the notes below)

  • In a large mixing bowl, mix the cream cheese and butter with an electric mixer on medium-high until smooth.
  • Add 3 cups of confectioner's sugar and mix well on medium speed. Then add the last 3 cups of confectioner's sugar and mix well on medium.
  • Scrape down the sides of the bowl and mix again at medium-high for about two minutes to make it fluffy. If the frosting is a little loose in consistency, pop it in the fridge to chill for about 20 minutes or so.
  • Cover cooled cake layers with frosting and serve.

Notes

This cake should be stored, well covered, in the refrigerator and can last for about 5 days when stored properly. This cake is best served chilled or at room temperature. If very cold, allow it to come closer to room temperature before serving.
For an even easier frosting, you could use pre-made canned cream cheese frosting.

Tips & FAQs:

Why do I need to use very ripe bananas?

Using very ripe bananas gives the most flavor to the cake.

What type of strawberry cake mix should I use?

You can use your favorite brand as long as it’s about a 15-ounce box.

Do I need to add the ingredients called for on the back of the cake mix box?

No, just add the ingredients listed in the recipe below.

I don’t have unsalted butter for the frosting, can I use salted butter?

Unsalted butter is best, but if you can’t get it, go ahead and use salted butter.

Tip for mixing the frosting:

Make sure that the cream cheese and the butter are close to room temperature so that the frosting mixes smooth.

How can I tell when this cake is done baking?

The cake is fully baked when a toothpick inserted into the center comes out with a few moist crumbs on it or clean, but no raw batter.

Can this cake be frozen?

This cake can be made ahead of time and frozen if desired. Let the baked cake cool completely, then wrap in plastic wrap and foil and place in the freezer for up to a month.
To thaw, place the wrapped cake on the counter at room temperature and let thaw completely, then remove the wrapping. Once defrosted, add the frosting.

How do I store this cake and how long does it last?

This cake should be stored, well covered, in the refrigerator and can last for about 5 days when stored properly.

Can this cake be made into cupcakes?

I have not tested this recipe out as cupcakes, but it may work just fine. Fill 2 cupcake pans (24 cupcakes) with cupcake liners and fill with batter about 2/3 of the way full. Bake at 350 degrees F and start checking for doneness at around 20-25 minutes.

What’s the best way to serve/eat this cake?

This cake is best served chilled or at room temperature. If very cold, allow it to come closer to room temperature before serving.
