This slow cooker 3-ingredient mint mojito dump cake is the kind of easy summer dessert that feels a little unexpected in the best way. It has that bright lime-and-mint flavor inspired by a classic mojito, but in a warm, buttery cake form that practically makes itself. It is perfect for busy days, cookouts, or when you need a low-effort dessert that still gets people asking for the recipe.
Serve this warm with vanilla ice cream, whipped cream, or a spoonful of lightly sweetened whipped topping to balance the citrusy mint flavor. For summer parties, I like to set it out with fresh lime wedges, extra chopped mint, and iced tea or sparkling lemonade so everyone can dress up their bowl a little and keep the whole dessert table feeling fresh and seasonal.
Slow Cooker 3-Ingredient Mint Mojito Dump Cake
Servings: 8
Ingredients
1 box white cake mix, about 15.25 ounces
1 can lime pie filling or key lime pie filling, about 21 ounces
1/2 cup mint mojito-style soda or lemon-lime soda with 1 tablespoon finely chopped fresh mint
Directions
1. Lightly coat the inside of a 4- to 6-quart slow cooker with nonstick spray or a thin layer of butter. Spread the lime pie filling evenly across the bottom.
2. Sprinkle the dry cake mix evenly over the filling, covering it from edge to edge without stirring.
3. Slowly pour the mint soda all over the top, then scatter the chopped fresh mint over everything. Do not mix; the layers will bake into a soft, cobbler-like cake.
4. Cover and cook on high for 2 to 2 1/2 hours or on low for 4 hours, until the top looks set and lightly golden around the edges and the filling is bubbling.
5. Turn off the slow cooker and let the cake rest uncovered for 10 to 15 minutes before serving. Spoon into bowls and top with extra mint or lime zest if you like.
Variations & Tips
Make it extra minty: If you want a stronger mojito-style flavor, add a little more finely chopped mint to the soda before pouring it over the cake mix. Let it sit for a minute so the mint flavor has time to infuse.
Use key lime for a sharper citrus flavor: Regular lime filling works well, but key lime filling gives the dessert a brighter, tangier finish that tastes especially good with whipped cream or vanilla ice cream.
Keep the topping from getting soggy: If your slow cooker runs hot and creates a lot of condensation, place a clean paper towel under the lid during the last 30 minutes of cooking to catch extra moisture. That helps the top stay more cake-like instead of overly wet.
Easy party serving tip: This dessert is best served warm straight from the slow cooker, which makes it ideal for potlucks and backyard dinners. I like to keep a small spoon nearby with bowls of mint, lime zest, and whipped cream so everyone can customize their serving.
