Ingredients

You’ll need the following for a medium-sized cake:

  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ½ cup creamy peanut butter
  • ½ cup unsalted butter (softened)
  • ¾ cup brown sugar (packed)
  • 2 large eggs
  • 3 medium ripe bananas (mashed)
  • 1 teaspoon vanilla extract
  • ½ cup milk (or buttermilk for extra moistness)

Optional for extra flavor:

  • ½ cup chocolate chips or chopped peanuts
  • A drizzle of honey on top before serving

Instructions

Step 1: Prepare the oven and pan

Preheat your oven to 180°C (350°F). Grease and line an 8-inch square or round cake pan with parchment paper.

Step 2: Mix dry ingredients

In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

Step 3: Cream peanut butter and butter

In a large bowl, beat the softened butter and peanut butter until creamy. Add the brown sugar and beat again until light and fluffy.

Step 4: Add eggs and bananas

Beat in the eggs one at a time, then stir in the mashed bananas and vanilla extract until smooth.

Step 5: Combine wet and dry

Gradually add the flour mixture, alternating with milk, until everything is just combined. Do not overmix—this keeps the cake soft.

Step 6: Bake the cake

Pour the batter into the prepared pan and smooth the top. Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean.

Step 7: Cool and serve

Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack. Serve plain, dusted with powdered sugar, or top with frosting.


Frosting Ideas

  • Peanut Butter Glaze: Mix ½ cup powdered sugar, 2 tablespoons peanut butter, and a little milk until smooth, then drizzle over the cake.
  • Cream Cheese Frosting: Blend cream cheese, powdered sugar, and a spoonful of peanut butter for a tangy, creamy topping.
  • Chocolate Ganache: Melt chocolate with cream for a rich finish that pairs beautifully with bananas and peanut butter.

Serving Suggestions

  • Serve warm with a scoop of vanilla ice cream.
  • Pack as a snack cake for school or office.
  • Enjoy with a cup of hot coffee or tea for a cozy treat.
