Ingredients

Scale

Cake Batter

1 standard chocolate cake mix
3 large eggs
Water or brewed coffee (amount according to cake mix instructions)
1 package instant chocolate pudding mix
6–8 Reese’s Peanut Butter Cups, chopped

Peanut Butter Swirl and Frosting

Creamy peanut butter (amount: approximately 1 cup for swirl and frosting)
Powdered sugar (about 1 cup for mixing with peanut butter)
2–4 tablespoons milk (to adjust consistency)

Topping

Additional chopped Reese’s Peanut Butter Cups for garnish

Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish thoroughly to prevent sticking.
Mix the Cake Batter: In a large bowl, combine the chocolate cake mix, 3 large eggs, and the specified amount of water or brewed coffee. Stir gently until the ingredients are just combined without overmixing.
Add Pudding Mix: Fold the instant chocolate pudding mix into the cake batter until evenly dispersed, enhancing moisture and fudginess.
Fold in Peanut Butter Cups: Chop 6 to 8 Reese’s Peanut Butter Cups and gently fold them into the batter to distribute their delicious pieces evenly.
Pour Batter into Pan: Pour the prepared batter into the greased baking dish and spread evenly.
Create the Earthquake Effect: In a separate bowl, mix creamy peanut butter with powdered sugar until smooth. Add 2-4 tablespoons of milk if the mixture is too thick. Drizzle this peanut butter mixture in a zigzag pattern over the cake batter; as it bakes, the swirl will marbledly intermingle.
Bake: Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out mostly clean with a few moist crumbs.
Cool and Prepare Frosting: Allow the cake to cool in the pan for about 15 minutes. Meanwhile, prepare a simple frosting by mixing more peanut butter with powdered sugar and a little milk until smooth and spreadable.
Frost and Garnish: Once the cake is cool, frost it evenly with the peanut butter frosting and sprinkle additional chopped Reese’s Peanut Butter Cups on top for an extra indulgent touch.

Notes

Do not overmix the batter to maintain a light and fluffy texture.
For extra flavor, consider adding 1 teaspoon of vanilla extract to the batter.
Serve warm with a scoop of vanilla ice cream for an exquisite contrast of temperatures and textures.
You can substitute water with brewed coffee for a richer chocolate taste.
Store the cake in an airtight container at room temperature for up to 2 days or refrigerate for up to a week.
For long-term storage, freeze individual slices wrapped tightly in plastic wrap and aluminum foil for up to 3 months. Thaw overnight in the refrigerator before serving.
