Ingredients
Scale
Main Dry Ingredients:
- 2 cups (250 g / 8.8 ounces) all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- ½ teaspoon ground cinnamon (optional)
Wet Ingredients and Flavorings:
- 3 ripe bananas, mashed (about 1 ½ cups)
- ½ cup (115 g / 4 ounces) unsalted butter, softened
- ½ cup (130 g / 4.6 ounces) creamy peanut butter
- 1 cup (200 g / 7 ounces) granulated sugar
- ½ cup (100 g / 3.5 ounces) brown sugar, packed
- 2 large eggs
- 1 teaspoon vanilla extract
- ½ cup (120 ml / 4 fluid ounces) buttermilk
Frosting Ingredients:
- ½ cup (130 g / 4.6 ounces) creamy peanut butter
- ¼ cup (60 g / 2 ounces) unsalted butter, softened
- 2 cups (240 g / 8.5 ounces) powdered sugar
- 2–3 tablespoons milk
- 1 teaspoon vanilla extract
Instructions
- Prepare the baking vessel by coating a 9×13-inch pan or two 9-inch round pans with grease and flour, then set the oven temperature to 350F (175C).
- Sift together flour, baking powder, baking soda, salt, and cinnamon in a medium mixing bowl, creating a uniform dry ingredient blend.
- Using an electric mixer, whip softened butter, peanut butter, granulated sugar, and brown sugar until the mixture becomes light and airy, approximately 2-3 minutes.
- Incorporate eggs individually into the creamed mixture, then blend in vanilla extract until fully integrated.
- Fold mashed bananas into the batter, then gradually alternate adding dry ingredients and buttermilk, ensuring minimal mixing to maintain the cake’s delicate texture.
- Transfer the batter into the prepared pan(s), distributing evenly and baking for 30-35 minutes in a 9×13-inch pan or 25-30 minutes in round pans until a toothpick emerges clean when inserted.
- Allow the cake to cool completely, creating the perfect canvas for frosting.
- Craft the frosting by blending peanut butter and softened butter until smooth, then gradually introduce powdered sugar, milk, and vanilla extract.
- Whip the frosting until it reaches a light, creamy consistency, adjusting milk quantity as needed for ideal spreadability.
- Generously apply the frosting across the cooled cake surface, optionally embellishing with chopped peanuts, fresh banana slices, or a decadent chocolate drizzle.
Notes
- Soften bananas beforehand by letting them ripen until dark and spotty for deeper, sweeter flavor and better moisture in the cake.
- Use natural creamy peanut butter without added sugars to control sweetness and prevent excessive graininess in the batter.
- Choose full-fat buttermilk for richer texture and more tender crumb, ensuring the cake stays moist and soft after baking.
- Swap regular flour with gluten-free flour blend for celiac or gluten-sensitive individuals without compromising the cake’s delicious taste and texture.
