Ingredients

For the Cake:

  • 2 cups all-purpose flour
  • 1 tsp baking powder
  • 1 tsp baking soda
  • ½ tsp salt
  • ½ cup unsalted butter, softened
  • ½ cup creamy peanut butter
  • 1 cup granulated sugar
  • ½ cup light brown sugar, packed
  • 2 large eggs
  • 1 tsp vanilla extract
  • 4 medium ripe bananas, mashed (about 1 ½ cups)
  • ½ cup buttermilk

For the Peanut Butter Frosting:

  • 1 cup unsalted butter, softened
  • 1 cup creamy peanut butter
  • 3 ½ cups powdered sugar
  • 3-4 tbsp heavy cream (or milk)
  • 1 tsp vanilla extract

Optional Garnishes:

  • Sliced bananas
  • Crushed peanuts
  • Drizzle of melted chocolate or peanut butter

Instructions

1. Prepare the Cake Batter:

  • Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper.
  • In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this aside.
  • In a large bowl, cream the softened butter, peanut butter, granulated sugar, and brown sugar until the mixture is light and fluffy. This should take about 3-4 minutes using an electric mixer.
  • Add the eggs, one at a time, mixing well after each addition. Then add the vanilla extract and mix again.
  • Stir in the mashed bananas until everything is well combined.
  • Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk. Start and end with the dry ingredients. Mix gently until just combined—be careful not to overmix.

2. Bake the Cake:

  • Pour the batter into the prepared pan and smooth the top with a spatula.
  • Bake for 30-35 minutes or until a toothpick inserted into the center of the cake comes out clean.
  • Let the cake cool completely in the pan before frosting it.

3. Make the Peanut Butter Frosting:

  • In a large bowl, beat the softened butter and peanut butter together until smooth and creamy.
  • Gradually add the powdered sugar, one cup at a time, mixing well after each addition.
  • Add the heavy cream and vanilla extract, continuing to beat until the frosting is light and fluffy. Adjust the consistency with more cream if needed.

4. Assemble the Cake:

  • Once the cake has completely cooled, spread the peanut butter frosting evenly over the top.
  • For an added touch, garnish with sliced bananas, crushed peanuts, or a drizzle of melted chocolate or peanut butter.

Additional Tips

  2. Room Temperature Ingredients: For best results, use butter, peanut butter, and eggs that are at room temperature. This ensures a smoother batter.
  3. Adjust Frosting Consistency: If your frosting is too thick, add an extra tablespoon or two of cream to loosen it. If it’s too thin, add more powdered sugar.
  4. Let the Cake Cool Completely: Allow the cake to cool completely before frosting to prevent the frosting from melting.
  5. Use a 9×13 Pan: If you prefer a thicker cake, use a smaller pan or bake the batter in two round cake pans and layer them with frosting in between.

Recipe Variations

  • Chocolate Chips: Add 1 cup of semi-sweet chocolate chips to the batter for extra chocolate flavor.
  • Nutty Frosting: Add chopped peanuts to the frosting for an extra crunch.
  • Vegan Version: Replace the eggs with flax eggs and use dairy-free butter and peanut butter for a vegan version.
  • Banana Chia Cake: Replace some of the flour with ground chia seeds for added texture and nutrition.
  • Caramel Drizzle: Add a drizzle of caramel sauce on top of the frosting for a sweet touch.

Freezing and Storage

  • Storage: Store leftover cake in an airtight container at room temperature for up to 3-4 days.

  • Freezing: You can freeze the cake (frosted or unfrosted) for up to 2-3 months. Wrap it tightly in plastic wrap and then in foil. Thaw at room temperature before serving.

FAQ Section
