Crockpot Churro Dulce de Leche Dump Cake

This Crockpot cinnamon churro dulce de leche cake is addictive! It's the easiest dessert you'll make all year: just spread caramel, dump on cake mix, sprinkle cinnamon sugar, dot with butter, and let the slow cooker do the rest.

In 2 1/2 hours you get a bubbling, buttery, crunchy-topped cake that tastes like a churro met a caramel sundae. Serve it warm with cold vanilla ice cream for the ultimate contrast.

A dump cake is the genius dessert that layers fruit or caramel with cake mix and butter, then bakes into a cobble-like treat. This version trades fruit for rich dulce de leche, and adds a cinnamon-sugar crust that crisps up like the outside of a churro.

The slow cooker keeps everything moist and tender, while the top turns golden and crunchy. It's a hands-off dessert that feels special enough for company but simple enough for a weeknight.

Ingredients

Why this recipe works

The slow cooker creates a steamy environment that gently bakes the cake mix into a soft, pudding-like cake while the butter and caramel meld together.

The cinnamon sugar on top caramelizes slightly, forming a crunchy, churro-like crust that contrasts with the gooey center. This method requires no mixing, no bowls, and no oven, so it's virtually foolproof.

Using cold butter pats instead of melted butter ensures the fat melts slowly, creating pockets of steam that lift the cake mix into a tender crumb. The dulce de leche at the bottom stays thick and saucy, bubbling up through the cake as it cooks. The result is a dessert with distinct layers of flavor and texture, all achieved with minimal effort.

Notes and substitutions

Spiced yellow cake mix already contains cinnamon and nutmeg, which complements the dulce de leche beautifully. If you only have plain yellow cake mix, add a teaspoon of cinnamon and a pinch of nutmeg to the dry mix before sprinkling.

Dulce de leche is sold in cans or jars near the ice cream toppings; it's thicker than caramel sauce and holds up better in the slow cooker.

Salted butter adds a savory note that balances the sweetness, but unsalted butter works too—just add a pinch of salt to the cinnamon sugar. A 6-quart slow cooker is ideal for this recipe; a smaller one will work but may cook faster, so check earlier. Serve the cake warm, straight from the slow cooker, for the best texture.
