  • 1 (15.25 oz) box chocolate cake mix
  • 1 (3.4 oz) box chocolate instant pudding mix
  • 1 ¾ cups milk
  • 1 (8 oz) package mini Reese’s PB Cups, chopped


  1. Begin by preheating your oven to 350 degrees Fahrenheit. Grease a 13×9 inch baking dish with non-stick spray, ensuring an easy release of your cake.
  2. In a large mixing bowl, combine the milk and chocolate instant pudding mix. Whisk vigorously until the pudding mix is fully incorporated into the milk, resulting in a smooth mixture.
  3. Add the chocolate cake mix to the pudding mixture, stirring until all ingredients are well combined. The batter will be thick and luscious, promising a moist and decadent cake.
  4. Gently fold in the chopped mini Reese’s PB Cups, ensuring an even distribution throughout the batter. Each bite will offer a delightful burst of peanut butter goodness amidst the rich chocolatey base.
  5. Pour the batter into the prepared baking dish, using a spatula to spread it out evenly. This ensures that every slice will be perfectly portioned and equally delicious.
  6. Place the baking dish in the preheated oven and bake for approximately 25 minutes, or until a toothpick inserted into the center comes out clean. Be prepared for your kitchen to be filled with the irresistible aroma of chocolate and peanut butter as the cake bakes to perfection.
  7. Once baked, remove the cake from the oven and allow it to cool slightly before serving. Whether you prefer to enjoy it warm or at room temperature, each slice promises a symphony of flavors that will leave you craving more.
  8. Serve your Peanut Butter Cup Dump Cake with a dollop of whipped cream or a scoop of vanilla ice cream for an extra indulgent treat. Garnish with additional chopped PB Cups for a decorative touch that will impress your guests.

Serving and Storage Tips:

  1. Serving Suggestions: When serving your Peanut Butter Cup Dump Cake, consider adding a drizzle of warm chocolate sauce or a sprinkle of powdered sugar for an extra touch of elegance. Fresh berries, such as raspberries or strawberries, make a delightful accompaniment, offering a burst of fruity freshness that complements the rich flavors of the cake.
  2. Warm or Room Temperature: While this cake is delicious when served warm straight from the oven, it’s equally delightful at room temperature. If you have leftovers, simply cover the baking dish with aluminum foil or transfer individual slices to an airtight container for storage.
  3. Reheating Instructions: To reheat individual slices, simply pop them in the microwave for a few seconds until warmed through. Alternatively, you can warm slices in a preheated oven at 350 degrees Fahrenheit for about 5-7 minutes. This will help restore the cake’s soft texture and melt the peanut butter cups slightly for an extra gooey experience.
  4. Storage: Store any leftover Peanut Butter Cup Dump Cake in the refrigerator for up to 3-4 days. Be sure to cover the cake tightly with plastic wrap or transfer it to an airtight container to prevent it from drying out. For longer storage, you can freeze the cake for up to 2-3 months. Simply wrap individual slices in plastic wrap and place them in a freezer-safe container or resealable plastic bag. Thaw overnight in the refrigerator before reheating or serving.
  5. Enjoying Leftovers: Don’t let any leftovers go to waste! Enjoy them as a sweet treat for breakfast alongside a cup of coffee or tea, or pack them in lunchboxes for a delightful midday pick-me-up. You can also get creative and repurpose leftover cake slices into new desserts, such as trifle, parfait, or cake pops.


  1. Nutty Twist: For an extra crunch and nutty flavor, add chopped peanuts or almonds to the cake batter before baking. You can also sprinkle some additional chopped nuts on top of the cake just before serving for a delightful garnish.
  2. Salted Caramel Drizzle: Take your Peanut Butter Cup Dump Cake to the next level by drizzling a generous amount of salted caramel sauce over each slice before serving. The sweet and salty combination will tantalize your taste buds and add an irresistible depth of flavor.
  3. Double Chocolate Delight: If you’re a true chocoholic, amp up the chocolate factor by adding chocolate chips or chunks to the cake batter along with the peanut butter cups. This will create an ultra-rich and decadent dessert that is sure to satisfy even the most intense chocolate cravings.
  4. Cookie Crumble Topping: For a fun twist, sprinkle crushed chocolate sandwich cookies or chocolate wafer crumbs over the top of the cake before baking. This will add a deliciously crunchy texture and a hint of cookie flavor to every bite.
  5. Marshmallow Fluff Swirl: Create a gooey and indulgent treat by swirling marshmallow fluff into the cake batter before baking. As the cake bakes, the marshmallow fluff will melt and create pockets of sweet, fluffy goodness throughout the cake.
  6. Frozen Peanut Butter Cups: For a refreshing twist, use frozen peanut butter cups instead of chopped ones in the cake batter. The frozen peanut butter cups will stay firm and add a delightful contrast to the warm, gooey cake when served.


  1. Can I use a different flavor of cake mix for this recipe?
    • Absolutely! While chocolate cake mix complements the peanut butter cups perfectly, feel free to experiment with other flavors such as vanilla, devil’s food, or even a chocolate fudge mix for a richer taste.
  2. Can I use regular-sized peanut butter cups instead of mini ones?
    • Yes, you can substitute regular-sized peanut butter cups for mini ones. Simply chop them into smaller pieces to ensure they distribute evenly throughout the cake batter.
  3. Is it necessary to use instant pudding mix?
    • Instant pudding mix helps enhance the moistness and texture of the cake, but if you prefer to omit it, you can still make the cake using just the cake mix and milk. The resulting cake may be slightly less moist, but still delicious.
  4. Can I make this cake gluten-free?
    • Yes, you can use a gluten-free chocolate cake mix and ensure that the other ingredients, such as the pudding mix and peanut butter cups, are also gluten-free. Always check the labels to confirm.
  5. How should I store leftovers?
    • Leftover cake can be stored in an airtight container in the refrigerator for 3-4 days. If you prefer to freeze it, wrap individual slices tightly in plastic wrap and store them in a freezer-safe container for up to 2-3 months.
  6. Can I make this cake ahead of time?
    • Yes, you can prepare the cake ahead of time and store it in the refrigerator. Simply allow it to come to room temperature or warm it slightly before serving.
  7. Can I omit the milk and use water instead?
    • While milk adds richness to the cake, you can substitute it with water if necessary. However, keep in mind that the texture and flavor may be slightly different.
  8. Can I use a different type of chocolate candy instead of peanut butter cups?
    • Certainly! Feel free to experiment with other types of chocolate candies such as chopped chocolate bars, chocolate chips, or even caramel-filled chocolates for a unique twist.
