Instructions
Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
In a bowl, whisk together 1 1/2 cups flour, 1 tsp baking powder, 1/2 tsp baking soda, and 1/4 tsp salt.
In a large bowl, beat together 1/2 cup butter and 1/2 cup peanut butter until creamy.
Gradually add 1 cup sugar, beating until fluffy. Add 2 eggs one at a time, beating well after each addition. Stir in 1 tsp vanilla extract.
Add the dry ingredients alternately with 1/2 cup buttermilk to the peanut butter mixture, beginning and ending with dry ingredients. Mix until just combined.
Gently stir in 1 cup M&M's.
Divide the batter evenly between the prepared pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
Allow the cakes to cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
In a large bowl, beat together 1/2 cup butter and 1 cup peanut butter until creamy for the frosting.
Gradually add 2 cups powdered sugar, beating until smooth. Add 1/4 cup heavy cream and 1 tsp vanilla extract, beating until fluffy.
Spread frosting on the top of one cake layer. Place the second layer on top and frost the top and sides of the cake.
Sprinkle additional M&M's on top of the frosted cake.
