Ingredients
Scale
- 1 box of chocolate cake mix (15.25 oz)
- 1 cup of water
- 1/2 cup of vegetable oil
- 3 large eggs
- 1 cup of creamy peanut butter
- 1 cup of powdered sugar
- 1 cup of semi-sweet chocolate chips
- 1 cup of chopped Reese’s Peanut Butter Cups (about 6–8 cups)
- 1/2 cup of chopped pecans (optional)
- 1 cup of whipped topping (for serving, optional)
Instructions
- Preheat your oven to 350°F (175°C).
- In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Mix on medium speed until well combined, about 2 minutes.
- In a separate bowl, mix together the creamy peanut butter and powdered sugar until smooth.
- Fold in the semi-sweet chocolate chips and chopped Reese’s Peanut Butter Cups into the chocolate cake batter.
- Grease a 9×13 inch baking pan with cooking spray or butter.
- Pour half of the chocolate cake batter into the prepared baking pan, spreading it evenly.
- Drop spoonfuls of the peanut butter mixture over the chocolate cake batter to create a swirl effect.
- Pour the remaining chocolate cake batter over the top, covering the peanut butter layer completely.
- If using, sprinkle chopped pecans on top of the batter.
- Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
- Let the cake cool in the pan for about 10-15 minutes.
- Gently loosen the edges from the pan and cut the cake into squares.
- Serve each piece with a dollop of whipped topping, if desired.
- Enjoy warm or at room temperature.
- Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for extended freshness.
- For longer storage, freeze individual pieces wrapped in plastic wrap for up to 3 months.
Notes
This cake can be stored in an airtight container for 3-4 days at room temperature or refrigerated for up to a week. Use room temperature ingredients for a smoother batter.
