This slow cooker 3-ingredient limoncello spritz dump cake is the kind of easy summer dessert that feels a little special without making extra work for the cook. It has that sunny lemon flavor people love at backyard parties, and the slow cooker keeps things simple while the cake turns soft, buttery, and syrupy underneath a golden top. It is especially handy for holidays, potlucks, and family cookouts when the oven is already busy and you want a dessert that practically makes itself.
Serve this cake warm straight from the slow cooker with a scoop of vanilla ice cream or a dollop of whipped cream to balance the bright lemon flavor. For a summer party spread, it also goes nicely with fresh berries, iced tea, lemonade, or even a cold sparkling water with lemon slices. If you are setting out a buffet, keep small bowls and spoons nearby so guests can help themselves.
Slow Cooker 3-Ingredient Limoncello Spritz Dump Cake
Servings: 8
Ingredients
1 box lemon cake mix, about 13.25 to 15.25 ounces
1 can lemon pie filling, 21 ounces
1 cup lemon-lime soda or prosecco-style lemon spritz soda
Directions
1. Lightly grease the inside of a 5- to 6-quart slow cooker. Spread the lemon pie filling evenly across the bottom.
2. Sprinkle the dry lemon cake mix evenly over the pie filling, covering the surface from edge to edge.
3. Slowly pour the lemon-lime soda over the top as evenly as possible. Do not stir. Cover with the lid.
4. Cook on high for 2 to 2 1/2 hours, or until the top looks set and lightly golden around the edges and the cake is bubbling underneath. Let it rest uncovered for 10 to 15 minutes before serving.
5. Spoon the warm cake into bowls and serve as is, or top with whipped cream or vanilla ice cream if you like.
Variations & Tips
Berry boost: Scatter 1 to 1 1/2 cups fresh blueberries or raspberries over the lemon pie filling before adding the cake mix. It gives the dessert a pretty red, white, and blue look that is especially nice for summer holidays.
Extra lemon flavor: For a stronger citrus taste, add 1 to 2 teaspoons finely grated lemon zest over the pie filling before layering the cake mix. That little touch makes the whole dessert smell wonderful.
Keep the layers intact: Resist the urge to stir after adding the soda. Dump cakes bake best when the layers stay mostly separate, which helps create that soft pudding-like bottom and lightly crisp top.
Slow cooker tip: Every slow cooker runs a little differently, so start checking near the 2-hour mark. If the top still looks very wet, give it a bit more time. If condensation is making the surface too damp, lay a clean kitchen towel under the lid for the last 20 minutes to catch extra moisture.
Make it party-friendly: Set the slow cooker to warm for serving and offer toppings in little bowls. Vanilla ice cream, whipped cream, crushed shortbread cookies, or fresh strawberries let everyone build their own dessert bowl.
