Chocolate Banana Cake with Chocolate Buttercream Frosting


I know, I know! ANOTHER banana bread/cake recipe. Ugh. I have like 20 now up on this site. But they are all so good and I always have the ingredients on hand so banana bread or cake is what I make! This one is so easy and with the buttercream frosting it can be used as a birthday cake. So delicious, so moist, my stomach hurts because I literally just ate 3 pieces. And my pieces are huge.

For the buttercream, I actually don’t even measure out my ingredients anymore. I’ve made SO MANY freaking cakes within the past 2 years that I can honestly say I’ve become a pro at buttercream. However, I did list the ingredients and about how much you need for this cake. But you will see or come to realize that every buttercream is different depending on the person and what you want for each cake. If you have any questions, send me a comment!

So, without anymore typing/reading, go start your ovens and let’s bake a cake!

What you will need:

9 x 13 inch glass bake pan sprayed with nonstick spray

2 cups granulated sugar
1 1/4 cups all-purpose flour
3/4 cup unsweetened cocoa powder
1 teaspoon baking soda
1 teaspoon baking powder
1/4 teaspoon salt
2 very ripe bananas, mashed
2 large eggs
1/2 cup warm water
1/2 cup milk
1/2 cup vegetable oil
1 teaspoon vanilla extract

For the chocolate buttercream: 

1/2 cup unsalted butter at room temp
2 tablespoons milk
1/4 cup unsweetened cocoa powder
2-3 cups powdered sugar

For the cake, preheat oven to 350 degrees fahrenheit. In a large bowl, whisk together the sugar, flour, cocoa powder, baking soda, baking powder and salt. Set aside. In another large bowl, whisk together the mashed bananas, eggs, water, milk, oil and vanilla. Pour the dry ingredients into the wet and stir or whisk until combined. The mixture is quite wet.

Pour into prepared pan and bake for 33-40 minutes. Mine was done right at 33 minutes. Allow to cool completely on a wire rack before frosting with the buttercream.

To make the buttercream: Beat the butter until smooth and creamy. Add cocoa powder and milk and beat until combined. Slowly add in powdered sugar until you reach desired consistency. Note: You cannot beat buttercream too much! Keep beating until you get what you want!

Frost the cake when it has cooled completely. Store covered at room temperature. Enjoy!
