Ingredients You’ll Need
You don’t need a long grocery list to pull off this masterpiece. Here’s what you need:
- 1 box of chocolate cake mix
- 1 (14 oz) can of sweetened condensed milk
- 1 stick (½ cup) of unsalted butter, sliced
- 2 cups of mini peanut butter cups (or chopped regular ones)
- 1 cup of peanut butter chips (optional, for extra richness)
- Vanilla ice cream or whipped cream (optional, for serving)
Ingredient Swaps and Add-ins
- Use brownie mix instead of cake mix for a fudgier texture.
- Add crushed pretzels for a salty crunch.
- Swap in almond butter cups for a different flavor twist.
How to Make Peanut Butter Cup Dump Cake
Step 1: Prep Your Pan and Preheat the Oven
- Preheat your oven to 350°F (175°C).
- Lightly grease a 9×13-inch baking dish with nonstick cooking spray or a little oil. This prevents sticking and makes cleanup easier.
second step: Layer the Peanut Butter Cups
- Scatter about 1½ cups of peanut butter cups evenly on the bottom of the greased baking dish.
- You can use minis or chop up regular-size cups. Freeze them for 10 minutes before chopping to avoid melting.
Step 3: Add Sweetened Milk and Cake Mix
- Pour the entire can of sweetened condensed milk over the peanut butter cups—don’t stir!
- Next, evenly sprinkle the dry chocolate cake mix right on top of the milk and candy layer. Again, don’t stir or press down—just let it sit there.
Step 4: Top with Butter and Chips
- Place the slices of butter all across the surface of the dry cake mix. Try to cover as much of the top as possible for even baking.
- If using, sprinkle peanut butter chips over the butter for an extra gooey, rich flavor.
Last Step: Bake, Top, and Serve
- Serve warm on its own or with a scoop of vanilla ice cream or a dollop of whipped cream. Total bliss!
- Bake for 35–40 minutes or until the top is golden brown and bubbling.
- Let it cool for 5–10 minutes out of the oven.
- Add the remaining ½ cup of peanut butter cups on top while still warm so they melt slightly.
Expert Cooking Tips for Peanut Butter Cup Dump Cake
1. Freeze the Peanut Butter Cups First
Before chopping, pop your peanut butter cups in the freezer for about 10–15 minutes. This prevents them from getting mushy or melting too quickly when layering.
2. Don’t Stir the Layers
Dump cakes are meant to be layered, not mixed. Keep each layer separate (especially the cake mix and condensed milk) for the signature gooey, molten texture.
3. Slice Butter Thin and Spread Evenly
Cut your butter into thin slices and lay them across the top to cover the entire cake mix. This helps the cake bake evenly and prevents dry spots.
4. Want Extra Gooeyness? Use More Condensed Milk
If you love that ultra-rich, sticky texture, add an extra 2–4 tablespoons of sweetened condensed milk. It’ll intensify the flavor and make every bite more indulgent.
Common Mistakes to Avoid
Avoid these pitfalls to ensure dump cake success:
- Don’t mix the layers—dump cakes are all about layering
- Make sure the butter covers the surface evenly
- Don’t overbake—it should be gooey in the center, not dry
How to Store and Reheat Leftovers
Good luck having leftovers… but if you do:
- Store in an airtight container in the fridge for up to 4 days
- To reheat, microwave for 20–30 seconds or warm in the oven at 300°F for 10 minutes
- Can be frozen for up to 1 month—just thaw overnight and warm before serving
Frequently Asked Questions (Peanut Butter Cup Dump Cake)
Can I use a different candy instead of peanut butter cups?
