Description

Easy Peanut Butter Cup Dump Cake recipe with layers of creamy peanut butter, chocolate chips, mini peanut butter cups, and golden cake topping. This no-mix dessert is perfect for potlucks, parties, and peanut butter lovers!


Ingredients

For the Dump Cake:

  • 1 (16 oz) jar creamy peanut butter
  • 1 box yellow cake mix (about 1518 oz)
  • 1 (14 oz) can sweetened condensed milk
  • 1 cup semi-sweet chocolate chips
  • 1 cup peanut butter-filled chocolate candies (like mini peanut butter cups), roughly chopped
  • 1 cup chopped peanuts (optional, for extra crunch)
  • ½ cup unsalted butter, sliced into pats


Instructions

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Lightly grease your 9×13-inch baking dish with butter or non-stick spray.

Step 2: Spread the Peanut Butter Base

Spread the entire jar of peanut butter evenly across the bottom of the baking dish. Don’t worry if it’s not perfectly smooth—close enough is good enough! This creates that amazing gooey layer.

Step 3: Add the Cake Mix

Sprinkle the yellow cake mix evenly over the peanut butter layer. Make sure it covers the entire surface. DO NOT STIR—that’s the beauty of a dump cake!

Step 4: Drizzle the Sweetened Condensed Milk

Pour the sweetened condensed milk evenly over the dry cake mix. Try to get it distributed across the whole pan. Again, resist the urge to stir! It’ll look a little messy, but trust the process.

Step 5: Add Your Mix-Ins

Scatter the chocolate chips, chopped peanut butter candies, and chopped peanuts (if using) all over the top. This is where the magic happens!

Step 6: Top with Butter

Distribute the butter slices evenly over the entire surface. These will melt down and help everything bake into golden perfection.

Step 7: Bake Until Golden

Bake for 35–40 minutes, until the edges are bubbling like crazy and the top is beautifully golden brown.

Step 8: Cool and Serve

Remove from the oven and let it rest for about 10 minutes before serving. This helps it firm up slightly so it’s easier to scoop.

Notes

  • Common mistake to avoid: Using light or fat-free sweetened condensed milk. Trust me, the full-fat version is what gives this dessert its incredible richness.
  • Smart shortcut: Buy pre-chopped peanuts to save time!
  • Don’t have mini peanut butter cups? Regular-sized Reese’s cups work great—just chop them up!
