Ingredients
Cake Base:
- 1 box Dark Chocolate Fudge Cake Mix (plus ingredients listed on the box: oil, eggs, water)
Peanut Butter Swirl:
- 8 oz softened cream cheese
- ½ cup softened butter
- ½ cup creamy peanut butter
- 1 teaspoon vanilla extract
- 4 cups powdered sugar
Toppings:
- ½ cup chocolate chips
- 1 cup mini Reese’s peanut butter cups, unwrapped and cut in halves
Instructions
1. Prepare the Oven and Pan
Preheat the oven to 350°F and grease a 9×13-inch baking dish with nonstick cooking spray.
2. Make the Cake Batter
In a large mixing bowl, prepare the chocolate fudge cake mix according to the package instructions. Pour the batter into the greased baking dish and set it aside.
3. Make the Peanut Butter Swirl
In a separate bowl, beat together the cream cheese, butter, peanut butter, and vanilla extract until smooth. Gradually mix in the powdered sugar, one cup at a time, until fully incorporated.
4. Assemble the Cake
Drop spoonfuls of the peanut butter mixture onto the chocolate cake batter. Gently swirl it into the batter using a knife or spatula—do not overmix.
5. Add the Toppings
Sprinkle the chocolate chips and Reese’s peanut butter cup halves evenly over the top.
6. Bake the Cake
Bake for 45-50 minutes, checking for doneness at 45 minutes. A toothpick inserted into the center should come out mostly clean.
7. Serve and Enjoy
Let the cake cool slightly before serving. It is best enjoyed warm, and for an extra indulgence, consider pairing it with a scoop of vanilla ice cream.
