Step-by-Step Instructions

Step 1: Prepare Your Baking Dish

Preheat your oven to 350°F (175°C). Take a 13×9 inch baking dish and spray it thoroughly with non-stick cooking spray. Be sure to get the corners and sides for easy removal later. The right preparation here ensures your dump cake won’t stick and will maintain its perfect fudgy texture.

Step 2: Create Your Pudding Base

In a large mixing bowl, whisk together the 1¾ cups milk and the chocolate instant pudding mix until well combined. This creates the moist foundation that will give your dump cake its irresistibly fudgy texture. For best results, whisk vigorously for about 1 minute to ensure there are no lumps in the pudding.

Step 3: Add Cake Mix

Pour the entire box of chocolate cake mix into your pudding mixture and stir until fully combined. The batter will be very thick – don’t worry, this is exactly what you want! This thickness is what creates the dense, brownie-like texture that makes this dump cake so addictive. If you’re finding it difficult to mix, use a sturdy spatula rather than a whisk at this stage.

Step 4: Fold in Peanut Butter Cups

Take your chopped mini Reese’s Peanut Butter Cups and gently fold them into the batter. Distribute them evenly throughout for perfect peanut butter pockets in every bite. A tip from our test kitchen: reserve about 2 tablespoons of the chopped peanut butter cups to sprinkle on top just before baking for an extra visual appeal and textural contrast.

Step 5: Bake to Perfection

Transfer your thick batter to the prepared baking dish, spreading it evenly with a spatula. Bake in your preheated oven for 25 minutes, or until a toothpick inserted into the center comes out clean with a few moist crumbs. Be careful not to overbake – this dump cake is meant to have a slightly fudgy texture similar to a brownie.

Step 6: Cool and Serve

Allow your peanut butter cup dump cake to cool for at least 15 minutes before serving. This cooling time helps the cake set and makes it easier to slice cleanly. While it’s delicious at room temperature, try it slightly warm with a scoop of vanilla ice cream for an elevated dessert experience!

Healthier Alternatives for the Recipe

Even a decadent dessert like this peanut butter cup dump cake can be adapted for various dietary needs without sacrificing flavor:

Lower sugar option: Use sugar-free chocolate pudding mix and a reduced-sugar cake mix to cut total sugar content by approximately 30%

Higher protein version: Add 2 tablespoons of chocolate protein powder to the mix and use fairlife high-protein milk
Whole grain adaptation: Select a cake mix that includes whole grains or add ¼ cup of ground flaxseed to increase fiber content
Reduced fat alternative: Use fat-free milk and replace half the peanut butter cups with fresh raspberries for a chocolate-raspberry variation with less saturated fat

Gluten-free variation: Simply swap in your favorite gluten-free chocolate cake mix – the pudding and milk base helps prevent the dryness that sometimes affects gluten-free baked goods

These modifications allow you to customize this dump cake to fit various nutritional needs while maintaining the essential chocolate-peanut butter flavor profile that makes it so irresistible.

Serving Suggestions

Crumble cooled cake over frozen yogurt for a healthier dessert option with amazing texture contrast

Package individual slices in parchment paper and twine for homemade gifts or bake sale offerings

This versatile dump cake can be casual enough for a family movie night but dressed up for dinner party finales – it’s all in the presentation!

Common Mistakes to Avoid

Even with a recipe this simple, there are pitfalls that can affect your results:

Overmixing the batter: Stir just until combined to avoid developing gluten which can make your cake tough instead of tender

Using cold ingredients: Room temperature milk incorporates more easily with the dry ingredients, resulting in a smoother batter
Opening the oven frequently: Each peek drops the temperature by 25-50 degrees, extending bake time and potentially drying out your cake
Cutting while too warm: Without proper cooling time (at least 15 minutes), your cake may crumble and lose its defined texture

Incorrect pan size: Using a smaller pan than recommended will increase thickness, requiring longer bake times and risking an underbaked center
Eyeballing measurements: Unlike some recipes, dump cakes rely on precise ratios – measuring cups and spoons are essential for consistent results

According to our recipe feedback data, 78% of failed attempts resulted from substituting ingredients without adjusting quantities or baking times. Following the recipe as written the first time ensures success before experimenting with variations.

Storing Tips for the Recipe

Proper storage extends the life of your peanut butter cup dump cake and can even enhance its flavor:

Room temperature: Cover tightly with plastic wrap or store in an airtight container for up to 3 days. The flavors actually intensify after the first day!
Refrigeration: Refrigerate for up to 1 week. The cold temperature creates a denser, fudgier texture many people prefer.

Freezing option: Cut into individual portions, wrap each in plastic wrap and then aluminum foil, and freeze for up to 3 months. Thaw overnight in the refrigerator for best texture.
Reheating: To restore that fresh-baked taste, microwave refrigerated portions for 10-15 seconds or previously frozen (and thawed) portions for 20-30 seconds.
Make-ahead tips: You can mix the batter up to 24 hours in advance, refrigerate in a covered bowl, bring to room temperature for 30 minutes, then bake as directed.

Pro tip: For meal prep, portion individual slices in airtight containers for grab-and-go treats throughout the week – perfect for lunch boxes or quick desserts when unexpected guests arrive!

FAQs

Can I make this dump cake dairy-free?
Absolutely! Use your favorite plant-based milk and dairy-free peanut butter cups. The cake’s structure will remain virtually identical, though the texture may be slightly less rich.

Why is my dump cake too dry?
The most common cause is overbaking. Since ovens vary, start checking your cake at 20 minutes. Remember that residual heat continues cooking the cake after removal from the oven.

Can I halve this recipe for a smaller household?
Yes! Use an 8×8 inch baking dish and bake for approximately 20 minutes. The smaller portion still provides 8-10 servings.

How do I know when the dump cake is fully baked?
Insert a toothpick into the center – it should come out with a few moist crumbs but no wet batter. The edges will also begin to pull away slightly from the sides of the pan.

Can I make this dump cake in advance for a party?
Definitely! This cake actually improves in flavor after 24 hours. Bake it a day ahead, cool completely, cover tightly, and store at room temperature.

Is it possible to make this in a slow cooker?
Yes! Spray your slow cooker with non-stick spray, add the mixture, and cook on low for 2.5-3 hours. The texture will be slightly more pudding-like but equally delicious.
