Just layer and bake. Peanut Butter Cup Dump Cake takes the classic concept and supercharges it with rich peanut butter flavor and the indulgence of everyone’s favorite candy.

Instructions for Making Peanut Butter Cup Dump Cake

Now let’s get to the delicious part. Here’s how you make magic — no mixers, no stress:

1. Preheat Your Equipment:
   Preheat your oven to 350°F (175°C). Grease your 9×13-inch baking dish lightly.
2. Combine Ingredients:
   No need to mix! Just have everything ready — chopped peanut butter cups, measured peanut butter, and melted butter.
3. Prepare Your Cooking Vessel:
   Pour the sweetened condensed milk into the greased baking dish and spread it out evenly.

   Scoop and serve straight from the pan — warm, gooey, and irresistible. Trust me, it’s worth every bite.

Texture & Flavor Secrets

This cake delivers the ultimate comfort texture — gooey melted pockets of chocolate, swirls of nutty peanut butter, and that crisp, buttery top layer. Every bite is a contrast between soft and crunchy, sweet and salty, warm and melty.

Cooking Tips & Tricks

Keep these in your back pocket for the perfect bake:

• Use an offset spatula to spread ingredients evenly.
• Don’t stir after layering — that’s the dump cake rule!
• Let cool slightly before serving so it firms up just enough.
• Add chopped peanuts for crunch if you love texture contrast.

What to Avoid

A few simple missteps can sabotage this sweet masterpiece:

• Using cold butter — it won’t soak into the cake mix properly.
• Stirring the cake mix — you’ll lose the distinct layered effect.
• Overbaking — leads to dry, crumbly texture.
• Under-buttering — results in powdery top spots.
