Some desserts earn a regular spot in the rotation simply because they make life easier, and this one definitely does. It leans on a few store-bought staples, comes together right in the slow cooker, and gives you that cozy homemade-dessert feeling with almost no effort. I love recipes like this on busy weekdays or when the grandkids are coming over, because you can set it up in minutes and let the crock do the work while the kitchen starts to smell amazing.
This sweet, buttery dessert is especially good served warm with a scoop of vanilla ice cream or a dollop of whipped cream on top. If you want to make it feel a little extra, add a few fresh blueberries and a bit of lemon zest before serving. For drinks, coffee, hot tea, or even a glass of cold milk all pair really nicely with the bright lemon flavor and jammy berries.
Slow Cooker 4-Ingredient Lemon Blueberry Dump Cake
Servings: 8
Ingredients
2 bags (12 ounces each) frozen blueberries
1/2 cup sugar
1 box dry lemon cake mix
1 stick butter, melted
Directions
1. Lightly coat the inside of the slow cooker insert with nonstick spray or a little butter if desired for easier cleanup. Pour the frozen blueberries into the bottom and spread them into an even layer. Sprinkle the sugar evenly over the berries.
2. Sprinkle the dry lemon cake mix evenly over the top of the blueberries and sugar, covering the fruit as completely as possible. Do not stir.
3. Drizzle the melted butter as evenly as you can over the dry cake mix. Try to cover most of the surface so the topping cooks up buttery and lightly golden. Place the lid on the slow cooker.
4. Cook on high for 2 to 2 1/2 hours or on low for 4 to 5 hours, until the blueberry filling is bubbling around the edges and the top is set. If you want the topping a little less wet, lay a paper towel under the lid for the last 30 minutes to catch extra condensation.
5. Turn off the slow cooker and let the dump cake rest for about 15 to 20 minutes before serving. Spoon into bowls or dessert plates and serve warm.
Variations & Tips
Add crunch: Sprinkle a small handful of sliced almonds or chopped pecans over the buttered cake mix before cooking if you want a little texture on top.
Make it extra lemony: Add a teaspoon of finely grated lemon zest over the blueberry layer before the cake mix goes on. It gives the whole dessert a brighter citrus flavor without adding extra work.
Use mixed berries: Swap one bag of blueberries for frozen blackberries or a berry blend for a slightly different flavor and color. Just keep the total fruit amount about the same so the texture stays balanced.
Watch for dry spots: If you notice patches of dry cake mix partway through cooking, drizzle over a little extra melted butter. Slow cookers can heat differently, so this quick fix helps the topping cook more evenly.
Plan ahead: Leftovers keep well in the refrigerator for up to 3 days. I like to scoop individual portions into containers so dessert is already handled for the next night.
