This 4-ingredient slow cooker summer raspberry dessert is the kind of easy treat busy families love, especially when you want something sweet without heating up the kitchen. Frozen raspberries melt down into a bright, jammy layer under a soft cake-like topping, giving you a cozy dessert that feels a little like a cobbler and a little like a dump cake. It is a simple, old-fashioned style recipe that is perfect for potlucks, Sunday dinners, or those nights when you want to make something special with almost no fuss.
Serve this warm with a scoop of vanilla ice cream or a dollop of whipped cream for a classic pairing. If you want to make it feel extra summery, add a few fresh raspberries on top or serve it alongside iced tea, lemonade, or hot coffee after dinner. For a fuller dessert table, it also goes nicely with simple butter cookies or a bowl of mixed fresh berries.
4-Ingredient Slow Cooker Summer Raspberry Dessert
Servings: 8
Ingredients
4 cups frozen raspberries
Directions
1. Lightly grease the inside of your slow cooker with butter or nonstick spray. Pour the frozen raspberries into the bottom and spread them into an even layer. Sprinkle the granulated sugar evenly over the berries.
2. Sprinkle the dry yellow cake mix evenly over the raspberries, covering the fruit as completely as you can without stirring.
3. Drizzle the melted butter as evenly as possible over the cake mix. Do not stir. Cover with the lid and cook on high for 2 to 2 1/2 hours, or until the fruit is bubbling around the edges and the top looks set.
4. Turn off the slow cooker and let the dessert rest uncovered for about 15 minutes so the topping can firm up a bit. Spoon into bowls and serve warm.
Variations & Tips
For a sweeter dessert: If your raspberries are especially tart, you can increase the sugar to 1/4 cup. This is a nice trick when serving kids or anyone who prefers a sweeter berry dessert.
Try a different cake mix: White cake mix or butter cake mix both work well here and give a slightly different flavor while keeping the recipe just as easy.
Add a little richness: A spoonful of whipped cream or a scoop of vanilla ice cream makes this dessert feel extra special for guests and balances the tart berry flavor beautifully.
Don’t stir the layers: It may seem unusual, but keeping the raspberries, cake mix, and butter in layers helps create the best texture. Stirring can make the topping gummy instead of soft and cobbler-like.
Watch your slow cooker: Slow cookers can run a little differently from one kitchen to another, so start checking near the 2-hour mark. You want bubbling fruit and a topping that looks set, not wet in the center.
