Ingredients
Scale
- 3 ripe bananas, mashed (about 1.5 cups)
- 1 cup (200 g / 7 oz) granulated sugar
- ½ cup (100 g / 3.5 oz) brown sugar, packed
- ½ cup (115 g / 4 oz) unsalted butter, softened
- ½ cup (130 g / 4.6 oz) creamy peanut butter
- ½ cup (120 ml / 4 fl oz) buttermilk
- 2 large eggs
- 2 cups (250 g / 8.8 oz) all-purpose flour
- 1 tsp baking powder
- 1 tsp baking soda
- 1 tsp vanilla extract
- ½ tsp salt
- ½ tsp ground cinnamon (optional)
- ½ cup (130 g / 4.6 oz) creamy peanut butter (for frosting)
- ¼ cup (60 g / 2 oz) unsalted butter, softened (for frosting)
- 2 cups (240 g / 8.5 oz) powdered sugar
- 2–3 tbsps milk
- 1 tsp vanilla extract (for frosting)
Instructions
- Preparation: Grease and flour a 9×13-inch pan or two 9-inch round pans, then preheat the oven to 350F (175C).
- Dry Ingredient Fusion: Sift flour, baking powder, baking soda, salt, and cinnamon into a medium bowl, creating a harmonious dry ingredient blend.
- Creaming Process: Utilize an electric mixer to whip butter, peanut butter, granulated sugar, and brown sugar until the mixture becomes ethereally light and voluminous.
- Egg Integration: Methodically incorporate eggs one at a time, then blend in vanilla extract until fully harmonized.
- Batter Development: Gently fold mashed bananas into the mixture, then alternately introduce dry ingredients and buttermilk with minimal stirring to preserve the cake’s delicate structure.
- Baking Ritual: Pour the batter into prepared pan(s), ensuring even distribution, and bake for 30-35 minutes (9×13-inch pan) or 25-30 minutes (round pans) until a toothpick comes out pristine.
- Cooling Phase: Allow the cake to cool completely, transforming into an ideal frosting canvas.
- Frosting Creation: Blend peanut butter and softened butter until silky smooth, gradually incorporating powdered sugar, milk, and vanilla extract.
- Frosting Finesse: Whip the mixture until achieving a light, creamy consistency, adjusting milk to ensure perfect spreadability.
- Final Embellishment: Lavishly apply frosting across the cooled cake, optionally adorning with chopped peanuts, fresh banana slices, or a luxurious chocolate drizzle.
Notes
- Ripeness Matters: Choose overripe bananas with dark brown spots for maximum sweetness and deeper banana flavor, enhancing the cake’s moisture and taste.
- Prevent Overmixing: Gently fold ingredients to maintain a tender crumb, stopping mixer when ingredients are just combined to avoid a dense, tough cake texture.
- Room Temperature Ingredients: Allow butter, eggs, and buttermilk to reach room temperature before mixing, ensuring smoother blending and more consistent cake structure.
- Moisture Control: If bananas are extremely wet, lightly pat them with paper towels to prevent excess liquid from making the cake soggy or affecting its rise.
