Ingredients

Why this recipe works

The slow cooker creates a unique texture that you can't get from an oven. The gentle, moist heat bakes the edges of the cake mix into a golden crust while the center remains soft and gooey.

This dual texture is the hallmark of a great dump cake—crispy edges, tender center, and a rich, creamy base from the sweetened condensed milk. The cake mix absorbs the milk mixture slowly, creating a dense, fudgy layer that's studded with melted white chocolate chips and bright sprinkles.

The dump-and-go method is foolproof. Because you don't stir the cake mix into the milk, the layers stay distinct. The dry mix forms a barrier that traps steam, which helps the cake cook evenly and keeps the center moist. The butter pats melt into the dry mix, creating a rich, buttery topping that crisps up at the edges. This hands-off approach means less cleanup and more time to enjoy the party.

Notes and substitutions

Use a 6-quart slow cooker for this recipe. A smaller cooker may cause the cake to overflow, while a larger one may cook it too quickly. The cake mix should be the classic Funfetti variety with rainbow sprinkles already mixed in. If you can't find it, use yellow cake mix and add extra sprinkles to the dry mix. White chocolate chips are key; they melt into creamy pockets that complement the vanilla flavor. For a richer version, use whole milk instead of low-fat.

The butter pats are important—they add richness and help the top crisp. Cut the butter into small pieces and scatter them evenly over the cake mix. Don't skip the sweetened condensed milk; it creates the creamy, pudding-like base that makes this dessert so indulgent.

If you prefer a less sweet dessert, use semi-sweet chocolate chips instead of white chocolate. The cake is best served warm, straight from the slow cooker, but it also tastes great at room temperature.

• Funfetti cake mix: Use yellow cake mix and add 1/4 cup rainbow sprinkles to the dry mix.
• white chocolate chips: Semi-sweet chocolate chips or butterscotch chips work well.
• milk: Any milk, including oat or almond milk, can be used.
