What is a peanut butter dump cake?

A peanut butter dump cake is a simple, layered dessert where ingredients like cake mix, peanut butter, and sweetened condensed milk are “dumped” into a baking dish and baked. It’s quick, easy, and incredibly delicious.

Can I use a different cake mix?

Yes! Yellow, spice, or chocolate cake mix works well. Each option gives a slightly different flavor but keeps the dessert moist and flavorful.

Can I make this gluten-free or dairy-free?

Yes. Use a gluten-free cake mix and substitute butter with a dairy-free alternative. You can also choose dairy-free chocolate chips.

How long does it keep?

Store in an airtight container at room temperature for 2–3 days or refrigerate up to a week. Reheat slightly before serving.

Absolutely! Whipped cream, chocolate drizzle, or extra chopped peanuts make this dessert even more indulgent.
