Ingredients for Peanut Butter Dump Cake Recipe

You’ll need:
1 box chocolate cake mix

Step by Step Peanut Butter Dump Cake Recipe
Follow these easy steps for a rich and gooey cake every time.
Step 1: Prepare the Baking Dish
Preheat your oven to 350°F. Lightly grease a 9×13 baking dish to prevent sticking.
Step 2: Add the Cake Mix
Pour the dry chocolate cake mix evenly into the baking dish. Spread it out gently so it forms a smooth layer.
Step 3: Layer the Peanut Butter
Spoon dollops of creamy peanut butter over the cake mix. Try to distribute it evenly for balanced flavor in every bite.
Step 4: Pour the Sweetened Condensed Milk
Drizzle the condensed milk over the top. This creates that signature soft, gooey texture.
Step 5: Add Chocolate Chips
Sprinkle chocolate chips evenly across the surface. They will melt beautifully during baking.
Step 6: Drizzle Melted Butter
Slowly pour melted butter over everything. Make sure most of the dry cake mix gets some butter coverage.
Step 7: Bake
Place the dish in the oven and bake for 35 to 40 minutes. The edges should look set while the center remains soft and fudgy.
Step 8: Top with Peanut Butter Cups
Once baked, add chopped peanut butter cups on top while the cake is still warm. They will slightly melt and create a glossy finish.
Pro Tips for the Best Peanut Butter Dump Cake

How to Store Peanut Butter Dump Cake

Cover leftovers tightly and store at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days.
To reheat, microwave a portion for 20 to 30 seconds. The peanut butter will soften again and the chocolate will melt beautifully.
