Ingredients

Scale

Cake Batter

1 standard chocolate cake mix
3 large eggs
Water (or brewed coffee for richer flavor) as per cake mix instructions
1 package instant chocolate pudding mix
6–8 Reese’s Peanut Butter Cups, chopped

Peanut Butter Mixture and Frosting

Creamy peanut butter (or crunchy for texture), quantity divided
Powdered sugar, quantity as needed
Milk, a little (for frosting consistency)

Instructions

Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish well to prevent sticking.
Mix Cake Batter: In a large mixing bowl, combine the chocolate cake mix, eggs, and water (or coffee). Stir gently until just combined, being careful not to overmix to keep the cake light and tender.
Add Chocolate Pudding Mix: Fold in the instant chocolate pudding mix thoroughly to ensure the batter is evenly enriched, which will add moisture and richness.
Incorporate Reese’s Cups: Chop 6 to 8 Reese’s Peanut Butter Cups and gently fold them into the cake batter so they are evenly distributed without melting.
Pour Batter: Transfer the batter to the prepared baking dish and spread it out evenly to create a uniform layer for baking.
Prepare Peanut Butter Drizzle: In a separate bowl, mix creamy peanut butter with powdered sugar until smooth and of a drizzling consistency. Drizzle this mixture over the surface of the cake batter in a zigzag or swirl pattern for marbled effect.
Bake: Bake in the preheated oven for 30-35 minutes or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs for moistness.
Cool: Remove from oven and let the cake cool in the pan for approximately 15 minutes to set.
Make Frosting and Finish Cake: Prepare the frosting by mixing additional creamy peanut butter with powdered sugar and a little milk until spreadable. Once the cake has cooled, spread this frosting evenly over the top.
Garnish: Sprinkle extra chopped Reese’s Peanut Butter Cups on top of the frosted cake for extra indulgence and texture.

Notes

Using brewed coffee instead of water enhances the chocolate flavor without making the cake taste like coffee.
For a crunchy texture, use crunchy peanut butter instead of creamy.
The ripple effect of peanut butter on top provides a beautiful visual and extra flavor layers.
Make sure not to overmix the batter to keep the cake from becoming dense.
Allow the cake to cool properly before frosting to avoid melting the frosting.
