How to Make Heavenly Peanut Butter Cup Dump Cake!
Step 1: Preheat & Prepare
Begin by preheating your oven to 350°F (175°C). That little bit of anticipation? Totally worth it. Next, grab your 9×13-inch baking dish and give it a good greasing—this is the trick to ensuring every slice of your Heavenly Peanut Butter Cup Dump Cake! lifts out easily, without leaving any precious bites behind.
Step 2: Layer the Peanut Butter
Scoop out that glorious cup of creamy peanut butter and use a spatula to evenly spread it on the bottom of your prepared dish. It’s your secret weapon for a truly luscious base, and trust me, friends will be asking what magic you used here!
Step 3: Mix the Cake Batter
In a large bowl, add your chocolate cake mix, melted butter, and milk. Stir it all together until you have a smooth, unified batter. Embrace the one-bowl ease of this step; it’s the heart of why this Heavenly Peanut Butter Cup Dump Cake! saves so much, well, time!
Step 4: Pour & Spread
Pour that velvety cake batter right over the peanut butter layer. Try to spread it gently and evenly—it doesn’t need to be perfect, but you want every corner to be covered so no creamy peanut butter goes unnoticed.
Step 5: Top with Peanut Butter Cups & Chocolate Chips
Here comes the fun! Shower the surface of your batter with the mini peanut butter cups and a generous handful of chocolate chips. As the cake bakes, these tiny candies turn into pockets of silky, melty perfection—exactly what makes this Heavenly Peanut Butter Cup Dump Cake! so addictive.
Step 6: Bake to Perfection
Pop the pan into the oven and bake for 35-40 minutes. The top should look beautifully set and a toothpick poked into the center should come out mostly clean (a little chocolate smudge is fine!). Let it cool so the layers can set—then get ready to serve up the dreamiest slices!
How to Serve Heavenly Peanut Butter Cup Dump Cake!

Garnishes
A dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of extra melted peanut butter can take this dessert to showstopper status. Sprinkle a few extra mini peanut butter cups or a dusting of cocoa powder if you’re feeling extra fancy; this is your peanut butter-chocolate canvas!
Side Dishes
Balance the richness of the 1 bowl peanut butter cup dump cake delight devours time with something crisp—try a fresh fruit salad, sliced strawberries, or simple vanilla yogurt. These light sides lift the whole dessert experience without overpowering the main event.
Creative Ways to Present
Spoon warm hunks into little mason jars for a fun twist on trifle, or cut the cake into cubes and serve in parfait glasses layered with ice cream. If you’re entertaining, mini cupcake liners make adorable single servings—because who can resist a personalized treat?
Make Ahead and Storage
Storing Leftovers
Leftover Heavenly Peanut Butter Cup Dump Cake! keeps remarkably well! Simply cover the baking dish tightly with foil or plastic wrap and store it in the refrigerator for up to 4 days. The flavors develop even more after a night in the fridge, if you can resist eating it all at once!
Freezing
If you want to stash some away, slice the cooled cake, wrap individual portions tightly in plastic wrap and place them in an airtight container or freezer bag. It’ll stay fresh for up to 2 months—ideal for satisfying midnight cravings or easy entertaining.
Reheating
To enjoy that ultra-gooey texture again, simply microwave slices for 20-30 seconds or warm them in a low oven until just heated through. Those peanut butter cups and chocolate chips will melt right back into bliss—no effort, all reward.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! If you love little peanut pieces and extra texture, crunchy peanut butter is a fun swap that adds a new dimension to your Heavenly Peanut Butter Cup Dump Cake!
What kind of milk works best?
Whole milk will give you the richest results, but skim, low-fat, or even non-dairy milks like almond or oat work beautifully too. Choose what you love or have on hand.
How do I know when the cake is done?
Look for the edges to pull away from the pan and the top to be set. A toothpick inserted in the center should come out mostly clean, with maybe a bit of melted chocolate for good measure!
Can I make this recipe gluten-free?
Yes! Use your favorite gluten-free chocolate cake mix and double-check your peanut butter cups and chips for gluten-free labels. The result is just as delicious and deeply chocolatey.
Can I skip the mini peanut butter cups?
Of course, but you’ll be missing out on the signature gooey, melty pockets that make the Heavenly Peanut Butter Cup Dump Cake! so decadent. Try swapping in peanut butter chips or extra chocolate chips if needed!
