Peanut Butter Cup Dump Cake Recipe – Cozy, chocolaty, and impossibly simple

Introduction

The kitchen smells like warm chocolate and peanut butter, and the soft hum of the oven feels like a hug.

Quick Recipe Snapshot

• Servings: 8–10
• Prep time: 10 minutes
• Cook time: 25 minutes
• Total time: 35 minutes
• Skill level: Easy
• Taste: rich chocolate + creamy peanut butter

Warm confidence: follow the steps and you’ll have a tender, gooey cake with melty peanut-butter pockets.

Ingredients You’ll Need

• 1 (15.25 oz) box chocolate cake mix
• 1 (3.4 oz) box chocolate instant pudding mix
• 1 ¾ cups milk
• 1 (8 oz) package mini Reese’s PB Cups, chopped

Chef notes:

• Use real milk for creaminess.
• Chop PB cups roughly for pockets.
• Non-stick spray = easy release.

How to Make It

1. First, preheat the oven to 350°F and grease a 13×9-inch baking dish with non-stick spray. The dish should shine lightly so the cake slips out easily.
2. Next, in a large bowl, whisk the milk and chocolate instant pudding mix together until smooth and lump-free. You want a glossy, thick pour.
3. Then add the chocolate cake mix to the pudding. Stir firmly until a thick, luscious batter forms. It will feel heavy and rich.
4. Meanwhile, fold in the chopped mini Reese’s PB Cups so they scatter evenly. Expect little bursts of orange-and-brown chocolate throughout the batter.
5. After that, scrape the batter into the prepared pan and spread it with a spatula until level. Smooth the top so slices bake uniformly.
6. Then bake for about 25 minutes, or until a toothpick placed near the center comes out clean or with a few moist crumbs. The edges will pull away slightly and the top will look set.
7. Finally, remove the pan and let the cake cool for 10–15 minutes before slicing. Serve warm for gooey pockets, or cool to room temperature for firmer slices.

Also, for a chocolate twist while baking, try my take on an apple butter cake for another cozy bake.

Kitchen Tips (From My Kitchen)

1. Time-saver: Chop PB cups in a zip-top bag with a rolling pin to save cleanup.
2. Common mistake + fix: If batter seems too dry, add 1–2 tablespoons more milk and stir until just combined.
3. Simple variation: Stir in a teaspoon of instant espresso for deeper chocolate flavor.

Serving Ideas

• Weeknight treat: Warm slice with a scoop of vanilla ice cream.
• Birthday dessert: Top with whipped cream and extra chopped PB cups.
• Holiday potluck: Cut into squares and garnish with sea salt flakes.
• Brunch sweet: Serve alongside coffee and fresh berries.
• For a retro duet, pair with a slice of butter pecan cake loaf at dessert buffet.

Optional garnish: extra mini PB cups, sea salt, or a drizzle of warmed chocolate.

Storing & Leftovers

• Fridge: Store covered for 3–4 days.
• Freezer: Wrap tightly and freeze up to 2 months.
• Reheat: Warm single slices in a microwave 12–20 seconds to keep pockets gooey.
  Leftover idea: Turn chilled slices into a decadent ice cream sandwich.

FAQs

A: Yes. Bake it a day ahead, then cool and cover. Rewarm briefly before serving for best texture.

Q: Can I substitute the mini PB cups?
A: You can use chopped full-size peanut butter cups or peanut butter chips, but chopped mini Reese’s give the best melt pockets for this Peanut Butter Cup Dump Cake.

Q: How do I know it’s done?
A: The toothpick should come out with a few moist crumbs. Also, the top will look set and the edges will pull away slightly from the pan.

Q: Can I freeze it?
A: Yes, freeze in airtight wrap. Thaw in the fridge overnight and warm gently.
