Quick Chocolate Banana Cake Is THE Answer To Your Ripe Bananas

Weekend meal, evening with friends - this chocolate cake recipe will make the dessert part easy

I made this chocolate banana cake for my husband’s tennis tournament.  There were a lot of people there and I have received many compliments on this chocolate cake.  My husband ate a piece before his match, and with it, he won his single and his double, annihilating his opponent. 

This chocolate banana cake recipe is handy to have when you have couple of ripe bananas that nobody wants to eat.  They are great in cakes; they add tenderness, natural sweetness, and fiber.  The sour cream in the cake adds a nice tang flavor and together with cocoa makes an exquisite cake.

It helps to have a blender or a food processor when making this cake.  I used my blender and I must say that this was a very easy and quick chocolate banana cake to make.  If you want to make this simple recipe ever easier, just sprinkle the baked cake with powdered sugar and skip the chocolate icing. 

I hope that you will like this tender chocolate banana cake and that you will come back for more homemade chocolate cake recipes.  You can always leave a comment at the bottom of this page or like me on Facebook.

  4. 2 large eggs
  5. 1 ½ teaspoon vanilla
  6. 10 tablespoons (142g) softened butter

  9. 1 teaspoon baking soda
  10. 1 teaspoon baking powder

Ingredients for the chocolate icing
  1. 8 ounces (227 grams) semisweet or bittersweet chocolate
  2. 3/4 cup (180 ml) heavy whipping cream

2.       Grease and line the bottom of your baking pan with parchment paper.  Grease again and flour. 

3.       In a blender or a food processor, mash the bananas with the sour cream until smooth.  Add the eggs, cocoa and vanilla and process shortly to blend.

4.       In a large bowl combine the dry ingredients and mix on low for a minute or two. 

5.       Add the butter and half of the chocolate banana mixture.  Mix on low speed until all dry ingredients are wet, increase the speed to medium and mix for 1.5 minutes.  This process strengthens the cake’s structure. 

6.       Add the remaining chocolate banana mixture and mix on high to incorporate all ingredients.  Scrape.

7.       Pour into the prepared pan and bake for 40-50 minutes.  Make sure to check for doneness in couple of spots before taking the cake out of the oven.  Cool for 10 minutes and invert onto a cake rack, unmold and cool off completely before icing. 

Prepare the chocolate icing and frost the cake:

1.      Break the chocolate into pieces and place in a metal bowl.

2.       Bring the cream and butter to boil and immediately remove from heat.  Pour the hot cream over the chocolate and let it stand for a minute. 

3.       Using a wire whisk, quickly stir to melt the remaining chocolate. 

4.       Cool off to room temperature and place in a fridge for 1 hour.  Whip the icing and frost the cake.

Tip:  Cover your cake plate with strips of parchment paper or aluminum foil to protect it from the icing.  I usually just slide 4 - 5 strips under the cake.
