When late-summer fruit cravings hit but the day is already packed, this simple slow cooker blackberry dessert is exactly the kind of recipe that saves dinner. It turns a bag of frozen blackberries and just a few pantry staples into a warm, jammy cobbler-style treat with almost no effort. I love recipes like this on busy weeknights because you can dump everything in, walk away, and come back to something that tastes like you spent a lot more time on it.
This dessert is especially good served warm with a scoop of vanilla ice cream or a spoonful of whipped cream on top. If you want to round it out for a casual gathering, pair it with hot coffee after dinner or serve smaller portions alongside grilled late-summer meals like burgers, chicken, or corn on the cob for an easy finish.
4-Ingredient Slow Cooker Blackberry Dump Dessert
Servings: 6 to 8
Ingredients
4 cups frozen blackberries
Directions
1. Lightly coat the inside of your slow cooker with nonstick spray or a little butter. Pour the frozen blackberries into the bottom and spread them into an even layer.
2. Sprinkle the sugar evenly over the blackberries. Then scatter the dry yellow cake mix over the top so the berries are fully covered.
3. Drizzle the melted butter as evenly as possible over the cake mix. Cover and cook on high for 2 to 2 1/2 hours, or on low for 4 hours, until the fruit is bubbling and the topping is set.
4. Turn off the slow cooker and let the dessert rest for 10 to 15 minutes before serving. Spoon it into bowls and serve warm on its own or with vanilla ice cream.
Variations & Tips
Add citrus: A little fresh lemon zest over the berries can brighten the blackberry flavor and make the whole dessert taste even more summery. This is a great move if your berries are especially sweet.
Make it extra cozy: Stir 1/2 teaspoon cinnamon into the cake mix before adding it to the slow cooker if you want a warmer, slightly spiced dessert that feels perfect going into early fall.
Watch the moisture: Frozen fruit can vary a bit, so if your dessert looks extra juicy near the end of cooking, prop the lid open slightly for the last 20 to 30 minutes to help some steam escape and thicken the filling.
Easy serving tip: This dessert is soft and spoonable rather than sliceable, so plan to serve it like a cobbler. If you're making it for company, set out bowls, ice cream, and whipped cream and let everyone build their own.
