Equipment
- 2 mixing bowls
- 1 Whisk or electric mixer
- 1 Measuring cup and spoons
- 1 Spatula
- 1 9-inch round or square cake pan
- 1 Cooling rack
- 1 Electric hand mixer or stand mixer (optional)
Ingredients
For the Cake:
- 2 ripe bananas mashed
- 1/2 cup peanut butter creamy or crunchy
- 1 1/2 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 cup sour cream at room temperature
- 1/2 teaspoon kosher salt
- 1/2 cup granulated sugar
- 1/2 cup packed brown sugar
- 2 large eggs
- 1/4 cup unsalted butter melted
- 1 teaspoon vanilla extract
- 1/2 cup buttermilk or milk with 1 tablespoon lemon juice
For the Peanut Butter Frosting:
- 1/2 cup peanut butter
- 1/4 cup unsalted butter softened
- 1 1/2 cups powdered sugar
- 1 teaspoon vanilla extract
- 1-2 tablespoons milk as needed for desired frosting consistency
Instructions
For the Cake:
- Preheat the oven to 350°F (175°C) and grease and flour a 9-inch round or square cake pan. In a large bowl, mash the ripe bananas with a fork or potato masher until smooth. Set aside.
- In another bowl, whisk together the flour, baking soda, and salt.
- In a separate bowl, beat together the peanut butter, sour cream, granulated sugar, brown sugar, eggs, melted butter, and vanilla extract until smooth and well-combined.
- Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk (or milk with lemon juice). Begin and end with the dry ingredients, mixing until just combined.
- Gently fold in the mashed bananas. Pour the batter into the prepared cake pan and smooth the top.
- Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Remove the cake from the oven and allow it to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
For the Frosting:
- In a medium bowl, beat together the peanut butter and softened butter until creamy and smooth. Gradually add the powdered sugar and vanilla extract, beating until smooth.
- Add 1-2 tablespoons of milk to adjust the frosting’s consistency to your liking. If you want a thicker frosting, use less milk.
- Once the cake has completely cooled, spread the peanut butter frosting evenly over the top.
Notes
❖ Banana Tip: Use very ripe bananas for the best flavor and texture. They’ll be sweeter and will give your cake that perfect banana essence.
❖ Peanut Butter Preference: If you like a bit of crunch in your cake, go for crunchy peanut butter. Otherwise, creamy peanut butter works perfectly well for a smooth consistency.
❖ Buttermilk Substitute: If you don’t have buttermilk, you can substitute it with regular milk. Just add a teaspoon of lemon juice to it and let it sit for 5 minutes before using.
❖ Frosting Variations: You can adjust the frosting’s consistency by adding more or less milk. For a thicker frosting, add less milk, and for a smoother texture, add a bit more.
