  • Chocolate cake mix: The foundation of moist, rich chocolate flavor and a tender crumb.
  • Eggs, oil, water: As called for on the cake mix box, these activate and bind the batter.
  • Peanut butter chips: Add creamy peanut butter pockets that melt beautifully inside the cake.
  • Chopped Reese’s Peanut Butter Cups: Burst of sweet, salty, melty peanut butter chocolate on top and throughout.
  • Chocolate chips: Another layer of melty chocolate to heighten the fudgy texture.
  • Sweetened condensed milk: Drizzled on top to infuse the cake with extra richness and gooey sweetness.
  • Whipped cream or vanilla ice cream: Optional but highly recommended for serving to cool and complement the warm cake’s intense flavors.

How to Make Reese’s Peanut Butter Cup Chocolate Cake {Crockpot} Recipe

Step 1: Prepare the Crockpot

Start by spraying your crockpot with nonstick cooking spray or lining it with a slow-cooker liner for easy cleanup. This setup ensures your cake won’t stick to the sides while it slowly bakes into perfectly gooey decadence.

Step 2: Mix the Cake Batter

Prepare the chocolate cake batter according to the package directions using the eggs, oil, and water. Make sure to stir everything until smooth to create the perfect base for the peanut butter and chocolate chips.

Step 3: Add Peanut Butter and Chocolate Chips

Fold in the peanut butter chips and chocolate chips directly into the batter. This step is where the magic begins as these morsels will melt within the cake, creating pockets of luscious flavor that transform every bite.

Step 4: Pour Batter and Add Reese’s Peanut Butter Cups

Pour the batter into your prepared crockpot, spreading it out evenly. Then sprinkle the chopped Reese’s Peanut Butter Cups over the top to ensure each serving boasts those irresistible peanut butter chunk surprises.

Step 5: Drizzle Sweetened Condensed Milk

Gently drizzle the sweetened condensed milk over the cake batter and peanut butter pieces. This step adds a creamy sweetness that seeps into the cake as it slow-cooks, giving that sought-after gooey texture and rich flavor.

Step 6: Cook Low and Slow

Cover your crockpot and cook on LOW for 2½ to 3 hours. You want the edges of the cake to be set while leaving the center just a bit gooey. Resist the urge to overcook – the fudgy center is what takes this cake from ordinary to extraordinary.

Step 7: Rest and Serve

Once done, turn off the heat and allow the cake to rest for 15 minutes before serving. This resting time helps the cake firm up slightly while keeping that luscious melt-in-your-mouth texture. Serve warm with a generous dollop of whipped cream or a scoop of vanilla ice cream for an unforgettable finish.

Garnishes

For serving, keep it simple yet indulgent by adding fresh whipped cream or vanilla ice cream atop each warm slice. A sprinkle of crushed peanut butter cups or a drizzle of chocolate syrup can boost the visual appeal and add even more flavor layers for your guests.

Side Dishes

This cake is a stand-alone superstar, but pairing it with light, fresh berries or a fruit salad cuts through the richness beautifully. A cup of strong coffee or bold black tea also pairs wonderfully with the deep chocolate and peanut butter flavors.

Creative Ways to Present

Turn your Reese’s Peanut Butter Cup Chocolate Cake {Crockpot} Recipe into an experience by serving it in rustic ramekins or individual slow cooker liners right out of the crockpot. For parties, consider layering slices with whipped cream and chopped nuts in a trifle dish, turning it into a decadent peanut butter chocolate trifle everyone will rave about.

Make Ahead and Storage

Storing Leftovers

Leftover cake keeps well when covered tightly in the refrigerator for up to three days. The rich flavors only deepen as it rests, and you can enjoy a slice as a decadent snack or dessert anytime.

Freezing

To freeze, wrap the cake tightly in plastic wrap and then in foil or an airtight container. Freeze for up to 2 months. Thaw overnight in the refrigerator, then warm gently before serving to revive that perfectly gooey texture.

Reheating

Reheat leftovers in the microwave in short bursts or in a warm oven until just heated through. Avoid overheating to keep the center soft and fudgy rather than dense or dry.

FAQs

Can I use homemade chocolate cake batter for this recipe?

Absolutely! While this recipe uses a box mix for convenience, homemade chocolate cake batter will also work beautifully and give you full control over ingredients.

What if I don’t have peanut butter chips?

If you can’t find peanut butter chips, you can substitute mini peanut butter cups chopped into bits or even swirl in some natural peanut butter into the batter for a similar effect.

How do I know when the cake is done?

The edges should be set and beginning to pull away from the sides, while the center still looks slightly gooey and soft. Use a toothpick to check – it should come out with moist crumbs but not raw batter.

Can I make this in a regular oven instead of a crockpot?

Yes, you can bake this cake in an oven at 350°F (175°C) for about 30-40 minutes. Just keep an eye on it to avoid overbaking, and consider adjusting the condensed milk drizzle accordingly.

Is this recipe suitable for vegetarians?

Yes, this Reese’s Peanut Butter Cup Chocolate Cake {Crockpot} Recipe is vegetarian-friendly, as it contains no meat or gelatin products.
