Ingredients
To make this irresistible Peanut Butter Cup Dump Cake, you will need:
-
1 box (15.25 oz) chocolate cake mix
-
1 box (3.4 oz) instant chocolate pudding mix
-
1¾ cups milk
-
1 package (8 oz) mini peanut butter cups, chopped into uneven bite sized pieces
Step by Step How to Make Peanut Butter Cup Dump Cake
Start by preheating your oven to 180°C or 350°F. Prepare a 13 x 9 inch baking dish by lightly coating it with non stick spray to prevent sticking.
In a large mixing bowl, whisk together the milk and instant chocolate pudding mix until smooth and well combined. This step helps create the rich and moist base for the cake.
Next, add the chocolate cake mix directly into the bowl. Stir everything together until fully blended. The batter will be thick, which is exactly what you want for this recipe. Avoid overmixing to keep the cake soft and tender.
Cut the mini peanut butter cups into uneven, bite sized chunks, then gently fold them into the batter so they are evenly distributed. This ensures pockets of melted peanut butter throughout the cake.
Transfer the batter into your prepared baking dish and spread it out evenly. Bake for about 25 minutes or until a skewer inserted into the center comes out with a few moist crumbs.
Allow the cake to cool slightly before serving. It is best enjoyed warm for maximum gooey goodness.
Helpful Tips
To achieve the best results, keep a few tips in mind. Do not overmix the batter once the ingredients are combined, as this can make the cake dense. The thick consistency of the batter is normal and helps create a rich texture. Chop the peanut butter cups unevenly to get varied bursts of flavor in every bite. For an extra indulgent touch, serve the cake warm so the chocolate and peanut butter remain soft and melty.
Substitutions And Variations
This recipe is wonderfully flexible. You can replace the peanut butter cups with chopped chocolate bars, caramel filled chocolates, or even pieces of white chocolate. Add chocolate chips for extra richness or mix in nuts for a bit of crunch. If you want to experiment, try using different flavored cake mixes such as vanilla, red velvet, or even peanut butter flavored cake. You can also drizzle caramel or chocolate sauce over the top before serving for added decadence.
Storage Instructions
Store any leftover cake in an airtight container in the refrigerator for up to three days. When you are ready to enjoy it again, reheat individual slices in the microwave for 15 to 20 seconds to restore the soft and gooey texture.
For longer storage, wrap individual slices tightly in plastic wrap and freeze for up to three months. Thaw overnight in the refrigerator before reheating and serving.
