This slow cooker 4-ingredient peach dump cake is one of those cozy, no-fuss desserts that feels like a hug in a bowl. Dump cakes have been potluck favorites in the Midwest for years because they’re simple, budget-friendly, and taste like something Grandma might have made on a Sunday afternoon. Using canned peaches means you can have that juicy, summery flavor any time of year—no peeling, slicing, or fussing. This is the kind of dessert you throw together on a busy morning, let it bubble away in the slow cooker, and then serve warm after dinner while everyone is still gathered around the table. It’s especially nice when you want something homemade but don’t have the time (or energy) for a complicated recipe.
This peach dump cake is wonderful served warm right out of the slow cooker, scooped into bowls. A big spoonful of vanilla ice cream or a dollop of whipped cream on top makes it feel extra special, especially for family movie nights or Sunday dinners. If you like a little contrast, serve it with a side of fresh berries or sliced strawberries for some brightness. For a more comforting, stick-to-your-ribs kind of dessert, pair it with a simple cup of coffee or hot tea for the adults and cold milk for the kids. It also makes a fun dessert for potlucks—just bring the slow cooker along and let everyone serve themselves.

Slow Cooker 4-Ingredient Peach Dump Cake

Ingredients
2 (29-ounce) cans sliced peaches in heavy syrup, undrained
1 (15.25-ounce) box yellow cake mix (dry mix only)
1/2 cup (1 stick) unsalted butter, melted
1 teaspoon ground cinnamon (optional but recommended)
Directions
Lightly grease the inside of a 6-quart slow cooker with nonstick cooking spray or a thin layer of butter to help prevent sticking.
Pour both cans of sliced peaches with all their syrup into the bottom of the slow cooker. Spread them out evenly so the peaches cover the bottom.
Sprinkle the dry yellow cake mix evenly over the peaches. Try to cover all the fruit, but don’t stir—this is what gives that classic dump cake texture.
In a small bowl or measuring cup, stir the ground cinnamon into the melted butter (if using). Slowly drizzle the melted butter mixture evenly over the dry cake mix, trying to moisten as much of the surface as you can.
Cover the slow cooker with the lid and cook on HIGH for 2.5–3 hours, or on LOW for 4–5 hours, until the top is set and looks like a soft, golden cobbler and the edges are bubbly.
Turn off the slow cooker and let the dessert sit, uncovered, for about 10–15 minutes to thicken slightly. Serve warm, scooped into bowls, with ice cream or whipped cream if you’d like.

 

Variations & Tips
• Extra-fruity: Add a small can of drained pineapple tidbits or an extra cup of frozen peaches on top of the canned peaches for more fruit and a little tang. • Spice it up: Swap the plain cinnamon for 1–2 teaspoons of apple pie spice or pumpkin pie spice for a cozy, fall-inspired flavor. This is especially nice if you’re serving it around the holidays. • Lighter sweetness: Use peaches in juice instead of heavy syrup and cut the butter down to 6 tablespoons. The texture will be a bit less rich but still satisfying. • Crunchy topping: If your family likes texture, sprinkle 1/2 cup chopped pecans or walnuts over the dry cake mix before adding the butter. Older kids often enjoy the crunch, while you can leave a nut-free section for younger or picky eaters. • For picky eaters: If anyone in your house doesn’t like visible peach slices, you can roughly chop the peaches in the can with kitchen scissors before dumping them in the slow cooker. The fruit will blend into more of a jammy layer, which some kids prefer. • Different cake mix: Try a white cake mix for a lighter flavor, or a spice cake mix if your family loves warm spices. Chocolate cake mix changes the flavor completely, but it can be fun for kids who are skeptical of fruit desserts. • Make-ahead tip: You can assemble everything in the slow cooker insert (without turning it on), cover, and refrigerate for a few hours earlier in the day. When you’re ready, pop the insert into the slow cooker base and start cooking so dessert is ready right after dinner.
