Servings

Ingredients
- 1 box chocolate cake mix + ingredients listed on the box (eggs, oil, water, etc.)
- ½ cup unsalted butter, melted
- 8 oz cream cheese, softened
- ½ cup creamy peanut butter
- ½ teaspoon vanilla extract
- 4 cups powdered sugar
- ½ cup semi-sweet chocolate chips
- 1 cup mini Reese’s Peanut Butter Cups, halved
Instructions
Step 1: Preheat and Prepare
- Preheat your oven to 350°F (175°C) .
- Grease a 9×13-inch glass baking dish or line it with parchment paper for easy removal.
Step 2: Make the Chocolate Cake Batter
- Prepare the chocolate cake batter according to the instructions on the box (typically eggs, oil, and water).
- Pour the batter evenly into the prepared baking dish and spread it out smoothly.
Step 3: Prepare the Peanut Butter Mixture
- In a large mixing bowl, beat the softened cream cheese and melted butter together until smooth and creamy.
- Add the peanut butter and vanilla extract, and beat until fully combined.
- Gradually mix in the powdered sugar, one cup at a time, until the mixture is light, fluffy, and spreadable.
Step 4: Assemble the Cake
- Dollop spoonfuls of the peanut butter mixture over the chocolate cake batter. Use a knife or spatula to gently swirl the peanut butter mixture into the cake batter, creating a marbled effect. Do not overmix—leave distinct swirls for a dramatic presentation.
- Sprinkle the semi-sweet chocolate chips and halved Reese’s Peanut Butter Cups evenly over the top of the cake.
Step 5: Bake
- Bake in the preheated oven for 45–55 minutes , or until the center is just set and a toothpick inserted into the cake comes out mostly clean (a few crumbs are okay).
Step 6: Cool and Serve
- Allow the cake to cool slightly before slicing and serving. For an extra indulgent treat, serve warm with a scoop of vanilla ice cream or a drizzle of chocolate syrup.
Pro Tips
- Peanut Butter Swirl: For a more pronounced peanut butter flavor, use crunchy peanut butter instead of creamy.
