- ½ tsp baking powder
- ½ tsp salt
- 1 tsp cinnamon
- ½ cup unsalted butter, softened 🧈
- ½ cup vegetable oil 🛢️
- 1 ¾ cups granulated sugar 🍚
- 2 large eggs 🥚

For the Peanut Butter Chocolate Frosting:
- ½ cup unsalted butter, softened
- ½ cup peanut butter (creamy or crunchy) 🥜
- ⅓ cup unsweetened cocoa powder 🍫
- 2 ½ cups powdered sugar, sifted
- ¼ cup milk (more if needed for texture)
- 1 tsp vanilla extract
👩🍳 Instructions
1. Preheat and Prep
Preheat oven to 350°F (175°C). Grease and line a 9×13-inch baking pan or two 9-inch round cake pans.
2. Mix the Dry Ingredients
In a medium bowl, whisk together flour, baking soda, baking powder, salt, and cinnamon. Set aside.
3. Cream Butter, Oil & Sugar
In a large bowl, beat the butter, oil, and sugar until light and fluffy (about 2-3 minutes). Add eggs one at a time, then mix in the vanilla.
4. Add Bananas and Buttermilk
Mix in the mashed bananas. Alternate adding the flour mixture and buttermilk, beginning and ending with flour. Mix until just combined—don’t overmix.
5. Bake
Pour the batter into the prepared pan(s). Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. Let cool completely.
🍫 Make the Frosting
- In a large bowl, beat the softened butter and peanut butter until smooth.
- Add the cocoa powder and powdered sugar, then gradually add milk and vanilla.
- Beat until fluffy and creamy. Add a splash more milk if the consistency is too thick.
🎂 Frost & Serve
Once the cake has completely cooled, spread the frosting generously over the top (and between layers if using round pans). Top with banana slices, chopped peanuts, or a drizzle of chocolate syrup for extra flair.
