Step-by-Step Instructions

Step 1: Make the Cake

Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

In a large bowl, whisk together flour, sugar, cocoa, baking powder, baking soda, and salt.

Add milk, oil, eggs, and vanilla. Beat until smooth.

Divide batter evenly into the pans and bake for 30–35 minutes or until a toothpick comes out clean.

Let cakes cool completely before frosting.

Step 2: Prepare the Frosting

Beat peanut butter and butter until creamy.

Add powdered sugar gradually, alternating with heavy cream, until smooth and fluffy.

Mix in vanilla extract.

Step 3: Assemble the Cake

Place one cake layer on a serving plate. Spread a thick layer of peanut butter frosting.

Sprinkle chopped Reese’s Peanut Butter Cups over the frosting.

Place the second cake layer on top. Frost the top and sides with remaining frosting.

Garnish with more Reese’s pieces and drizzle with chocolate if desired.

Tips for Success
