Ingredients

Scale

Cake Batter

  • 1 15.25 oz. chocolate cake mix
  • 1 18.3 oz. brownie mix
  • 4 eggs
  • 1 1/4 cups water
  • 1 cup oil

Peanut Butter Cream Cheese Filling

  • 1 8 ounces package cream cheese (softened)
  • ⅓ cup sugar
  • 1 egg
  • ¼ cup peanut butter

Chocolate Ganache

  • ½ cup chocolate chips (semi-sweet)
  • ½ cup heavy whipping cream

Garnish

  • ½ cup peanut butter (for drizzling)
  • mini peanut butter cups (Mini Reese’s cups for garnish)

Instructions

  1. Preheat and prepare pan: Preheat the oven to 350°F (175°C) and grease a 10-cup bundt pan thoroughly to ensure the cake releases easily.
  2. Mix cake and brownie batter: In a large mixing bowl, combine the chocolate cake mix, brownie mix, 4 eggs, 1 1/4 cups water, and 1 cup oil. Follow the instructions on the cake and brownie mix boxes to ensure correct liquid ratios and ingredients, adjusting as needed.
  3. Pour first batter layer: Pour half of the combined batter evenly into the prepared bundt pan, spreading it gently to cover the bottom.
  4. Prepare peanut butter cream cheese filling: In a medium bowl, mix together the softened cream cheese, ⅓ cup sugar, 1 egg, and ¼ cup peanut butter until smooth and creamy with no lumps.
  5. Add filling to batter: Spoon dollops of the peanut butter mixture evenly over the layer of batter in the bundt pan.
  6. Top with remaining batter: Carefully spoon the remaining half of the batter over the peanut butter filling, spreading gently to cover.
  7. Bake the cake: Place the bundt pan on a baking sheet to catch any drips and bake in the preheated oven for 50-60 minutes. Check doneness by inserting a toothpick into the center; it should come out clean.
  8. Cool the cake: Let the cake cool in the pan for 10 minutes, then invert it onto a wire rack to cool completely before decorating.
  9. Make chocolate ganache: Heat the ½ cup heavy whipping cream in the microwave for 30 seconds to 1 minute until hot. Add the ½ cup semi-sweet chocolate chips and let sit for 5 minutes. Stir until the mixture is melted, smooth, and glossy.
  10. Drizzle ganache on cake: Drizzle the chocolate ganache evenly over the top of the cooled bundt cake.
  11. Prepare peanut butter drizzle: In a small microwave-safe bowl, melt ½ cup peanut butter for 20 seconds until pourable.
  12. Drizzle peanut butter: Drizzle the melted peanut butter over the top of the cake, adding a rich layer of flavor.
  13. Garnish with mini peanut butter cups: Sprinkle chopped or whole mini Reese’s peanut butter cups on top for an extra special touch.
  14. Serve and enjoy: Slice and serve this rich, moist bundt cake for dessert or special occasions.

Notes

  • Make sure to adjust the liquid and egg quantities based on the specific instructions on your cake and brownie mix boxes for best results.
  • Allow the cake to cool completely before adding the ganache and peanut butter drizzles to prevent melting and sliding.
  • Use a non-stick spray or butter and flour to grease the bundt pan thoroughly for easy cake removal.
  • You can substitute peanut butter cups for other chocolate candies if preferred.
  • Store leftovers covered at room temperature for 2 days or refrigerate for up to a week.
