Expert Tips for the Perfect Dump Cake

Making the ultimate Peanut Butter Cup Dump Cake is easy. Follow these tips to ensure your dessert impresses every time:

  • Do Not Overmix: Mix the cake mix, peanut butter, and melted butter until just combined. Overmixing can make the cake dense.
  • Even Layers Are Key: Spread each ingredient evenly. This guarantees a perfect blend of flavors and textures in every bite.
  • Check the Cake Early: Oven temps vary. Check your cake a bit before the time’s up. A toothpick should come out clean or with a few crumbs.
  • Let It Cool: Cool the cake slightly before serving. This sets the layers and makes cutting easier. Serving it warm enhances the flavors.
  • Customize Your Toppings: Feel free to get creative. Add caramel drizzle or sea salt on top for extra flavor.
  • Store Properly: Cover leftovers with plastic wrap or in an airtight container. Store at room temperature for a day or refrigerate for up to 5 days. Reheat in the microwave for a few seconds if needed.
  • Serve with Ice Cream: Vanilla ice cream with warm cake offers a delightful contrast. It’s an indulgent treat.

These simple adjustments can elevate your dump cake from good to great, ensuring a delicious outcome every time.


What is the biggest mistake to avoid when making a dump cake?

The most significant mistake is overmixing the batter or disturbing the layers once they’re assembled. Dump cakes rely on the simplicity of layering ingredients without stirring them together. This ensures the right texture and flavor distribution.

Is dump cake supposed to be gooey?

Yes, dump cakes are meant to have a gooey, moist texture. The milk poured over the mix and the melting chips contribute to this unique texture. If you prefer a firmer cake, you can slightly reduce the amount of milk or bake it a bit longer, but the gooeyness is part of the charm.

Can you leave a dump cake out overnight?

It’s generally safe to leave the dump cake out at room temperature overnight, especially if your kitchen is cool. However, for longer storage, it’s best to cover it and refrigerate it to maintain freshness and prevent spoilage.

Do dump cakes taste good?

Absolutely! Despite their simplicity, dump cakes are delicious. They offer a rich, comforting flavor with minimal effort. The combination of ingredients like in the Peanut Butter Cup Dump Cake ensures a tasty dessert that’s both easy to make and satisfying.

Can I use a different cake mix or add-ins?

Yes, dump cakes are incredibly versatile. Feel free to experiment with different cake mix flavors or add-ins based on your preferences. For example, using a vanilla cake mix instead of chocolate could offer a new flavor profile. Just keep the proportions similar to ensure the cake sets properly.

How can I make my dump cake less sweet?

If you find the cake too sweet, consider using less sugar in the cake mix (if made from scratch) or choosing add-ins that are less sweet, such as dark chocolate chips instead of semi-sweet or peanut butter chips. Another option is to serve the cake with unsweetened whipped cream or a dollop of sour cream to balance the sweetness.

  • Whipped Cream: A dollop of whipped cream on top of each serving adds a light, creamy texture that complements the dense, rich cake.
  • Chocolate or Peanut Butter Drizzle: Enhance the flavors by drizzling melted chocolate or peanut butter over the top before serving.

Indulge in the rich, gooey goodness of our Peanut Butter Cup Dump Cake. It’s the perfect blend of chocolate and peanut butter in an easy-to-make dessert that everyone will love.


  • 1 box (15.25 ounces) chocolate cake mix: This serves as the effortless foundation of our cake.
  • 1 cup creamy peanut butter: For that rich, peanut buttery goodness that melds perfectly with chocolate.
  • 1 1/2 cups milk: This helps to moisten the cake mix, creating a perfectly tender texture.
  • 1/2 cup unsalted butter, melted: Adds richness and depth to the cake’s flavor profile.
  • 1 cup semi-sweet chocolate chips: For those pockets of melty chocolate that elevate every bite.
  • 1 cup peanut butter chips: To intensify the peanut butter flavor throughout the cake.
  • 1 1/2 cups coarsely chopped peanut butter cups (approximately 12 standard-sized cups): The pièce de résistance adds texture and an extra layer of indulgence.


  1. Preheat Your Oven: Begin by heating your oven to 350°F (175°C). This ensures your cake cooks evenly and rises perfectly.
  2. Prepare the Baking Dish: Grease a 9×13-inch baking dish. A light coating of butter or non-stick spray will prevent sticking and make serving easier.
  3. Mix the Base: In a large mixing bowl, combine the chocolate cake mix, creamy peanut butter, and melted unsalted butter. Stir until the mixture becomes crumbly and well combined. This forms the rich, flavorful base of your cake.
  4. Layer the Cake: Spread the cake mixture evenly into the bottom of your greased baking dish. This layering technique is key to achieving the perfect dump cake texture.
  5. Add the Milk: Pour the milk evenly over the cake mixture. Do not mix. The milk will seep into the cake mix during baking, creating a moist and tender crumb.
  6. Sprinkle the Chips: Evenly distribute the semi-sweet chocolate chips and peanut butter chips over the milk layer. These chips add delightful bursts of flavor to every bite.
  7. Top with Peanut Butter Cups: Scatter the coarsely chopped peanut butter cups over the top. This not only adds to the flavor but also gives the cake a visually appealing finish.
  8. Bake to Perfection: Place the baking dish in the preheated oven and bake for 40-45 minutes, or until the cake is set and the top is golden brown. The baking time may vary slightly depending on your oven, so keep an eye on it as it nears completion.
  9. Cool and Serve: Remove the cake from the oven and let it cool slightly before serving. This dessert can be enjoyed warm or at room temperature. For an extra treat, serve with a scoop of vanilla ice cream.


  • For a less sweet version, consider using dark chocolate chips instead of semi-sweet.
  • The cake can be stored at room temperature for up to 24 hours or refrigerated for longer freshness.
  • Feel free to customize with your favorite toppings like caramel drizzle or a sprinkle of sea salt for an extra flavor boost.
