Essential Ingredients for Peanut Butter Cup Dump Cake
Core Ingredients You’ll Need
- Boxed Chocolate Cake Mix
Any standard chocolate cake mix will do. Go for devil’s food, fudge cake, or even dark chocolate if you want a richer flavor. This forms the base and structure of the dump cake—think fluffy yet dense, with just the right amount of moisture. - Peanut Butter Cups
The stars of the show. Use mini Reese’s or chop up the regular ones. They melt into the cake and create gooey pockets of peanut buttery goodness. Want to level up the flavor? Freeze them before baking so they hold their shape longer while melting slightly. - Sweetened Condensed Milk or Heavy Cream
These ingredients help keep the cake moist and rich. Sweetened condensed milk adds extra sweetness and a caramel-like texture. Meanwhile, heavy cream tones down the sugar if you’re looking for balance. - Butter (Melted or Cubed)
Butter ensures everything melds together perfectly. You’ll scatter it over the top—don’t stir! Just let it melt and do its magic. - Optional Toppings
Want to jazz it up? Toss in some semi-sweet chocolate chips, crushed peanuts, or a handful of mini marshmallows. These add extra layers of texture and flavor without complicating the process.
How to Make Peanut Butter Cup Dump Cake Step-by-Step
Step 1: Preheat and Prep
First things first—preheat your oven to 350°F (175°C). While that’s warming up, grab a 9×13-inch baking dish and lightly grease it with butter or nonstick spray. No need for parchment—this cake likes to stick around, in the best way possible.
Step 2: Layer the Good Stuff
Start by spreading a generous layer of chopped peanut butter cups across the bottom of your dish. No measuring drama here—just make sure they cover the surface well.
Next, evenly sprinkle the dry chocolate cake mix directly on top of the peanut butter cups. Yes, you read that right—don’t mix it. That’s the magic of a dump cake!
Then pour sweetened condensed milk (or heavy cream if you’re dialing down the sugar) evenly over the cake mix. Don’t stir—let gravity and the oven do the work.
Scatter cubed or melted butter over everything, trying to distribute it across the top as evenly as possible. The butter will melt and seep down, pulling all the layers together in rich harmony.
Step 3: Bake to Perfection
Slide the pan into the oven and bake for 35–40 minutes, or until the top is set and the edges are bubbly and golden. Want it extra gooey? Pull it out at 35. Prefer a firmer texture? Give it an extra 5 minutes.
Step 4: Cool (Just a Little) & Serve
Let your cake cool for 10–15 minutes before serving. It’ll still be warm, gooey, and ready to scoop. Serve with a dollop of whipped cream or a scoop of vanilla ice cream for a little extra oomph.
Serve & Store Your Peanut Butter Cup Dump Cake
Serve It with Flair
Slice the dump cake while it’s still warm—gooey pockets taste best hot. Add a scoop of vanilla ice cream or a dollop of whipped cream for creamy contrast. A sprinkle of chopped peanuts on top gives a lovely crunch and enhances that peanut butter flavor.
Add a Drizzle
Finish with melted peanut butter or salted caramel sauce. Just spoon it over each slice for a decadent touch that ties the flavors together.
Store Leftovers Smartly
Cover the cooling cake loosely with foil or plastic wrap. It keeps well at room temperature for 1–2 days—just reheat in the oven at 300°F for 10 minutes to restore that fresh-baked feel.
Freeze for Later
Want to save some for later? Cut into squares, wrap individually, and freeze. Reheat in a 350°F oven for 15–20 minutes (from frozen) or 5–7 minutes if thawed.
Quick Tips for Perfect Peanut Butter Cup Dump Cake
Grease the Pan Well
Use a nonstick spray or rub with butter. Even gluten-free mixes will cling if you skip this step.
Even Cup Distribution
Lay out peanut butter cups in rows. This way, every slice gets a gooey bite—no dry spots.
Top for Crunch
Sprinkle gluten-free oats or crushed graham crackers before baking. Adds a golden, crisp finish.
Don’t Overmix
Just layer. Resist the urge to stir. Dump cakes are better when the layers bake into each other.
Watch the Bake Time
Check at 25 minutes. The edges should be golden, and the center barely set.
Toothpick Test
Insert one in the center. A few moist crumbs mean it’s ready. Wet batter? Bake 2–3 minutes more.
Let It Rest
Cool for 10 minutes before slicing. It helps set the cake and keeps it from crumbling.
Serve It Warm
Best with a scoop of vanilla ice cream or a drizzle of warm almond butter.
Frequently Asked Questions About Peanut Butter Cup Dump Cake
Can I use different types of candy instead of peanut butter cups?
Absolutely! While Reese’s peanut butter cups steal the show, feel free to experiment. Try chopped Snickers, Milky Way, M&M’s, or even chocolate-covered pretzels. Each adds a unique twist to the texture and flavor. Just make sure whatever candy you choose is chopped into bite-sized pieces so it melts evenly throughout the cake.
How do I make dump cake less sweet?
If you’ve got a less-sweet tooth, try using heavy cream instead of sweetened condensed milk, or opt for a less sugary chocolate cake mix. Also, choose dark chocolate peanut butter cups instead of milk chocolate to balance the flavor. Topping it with unsweetened whipped cream can also mellow the overall sweetness.
Is it okay to make dump cake ahead of time?
Yes, and in fact, it tastes even better the next day. Once baked and cooled, cover it with plastic wrap or store it in an airtight container. Keep it at room temperature for up to 2 days, or refrigerate for up to 5 days. Warm it slightly before serving to revive its gooey goodness.
What’s the difference between a dump cake and a poke cake?
Great question! A dump cake involves layering all ingredients without mixing, while a poke cake is baked first and then poked to let in fillings like pudding or sauce. Dump cakes are more rustic and hands-off—perfect for lazy baking days!
Can I freeze dump cake?
You bet! Let it cool completely, then freeze in an airtight container for up to 3 months. Thaw overnight and reheat gently in the oven or microwave when ready to enjoy.
