Ingredients
Scale
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1/2 cup creamy peanut butter
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 3/4 cup buttermilk
- 1 cup M&M’s (plus extra for topping)
Instructions
- Preheat oven to 350°F (175°C). Grease and flour an 8-inch round cake pan or line with parchment paper.
- In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
- In a large bowl, beat butter and peanut butter together until smooth. Add sugar and beat until light and fluffy.
- Beat in eggs one at a time, then add vanilla extract.
- Gradually add the flour mixture, alternating with the buttermilk, beginning and ending with the flour mixture.
- Fold in 1 cup of M&M’s.
- Pour batter into the prepared cake pan and smooth the top. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
- While the cake is cooling, prepare the frosting: Beat together 1/2 cup unsalted butter and 3/4 cup creamy peanut butter until fluffy. Add 1 1/2 cups powdered sugar and 2–3 tablespoons milk, and beat until smooth and spreadable.
- Frost the cooled cake and top with extra M&M’s.
Notes
- Use mini M&M’s for better distribution throughout the cake batter.
- Chill the frosted cake for 20 minutes before slicing for cleaner cuts.
- Add chopped roasted peanuts on top for an extra crunchy texture.
