Slow Cooker 3-Ingredient Sweet Potato Cobbler

There are some desserts that feel like autumn in a bowl, and this Slow Cooker 3-Ingredient Sweet Potato Cobbler is exactly that. It takes the cozy, old-fashioned comfort of a classic sweet potato cobbler and makes it almost effortless—just canned sweet potatoes, a box of spice cake mix, and melted butter, all simmering together into something warm, sweet, and deeply satisfying.

What I love most about this recipe is how the sweet potatoes turn soft and jammy as they cook, while the cake mix and butter bake into a golden, tender topping that soaks up all that syrupy goodness. It comes out more like a spoonable cobbler than a crisp, which makes it even more comforting. Serve it warm with a scoop of vanilla ice cream, and watch it disappear.

Why You’ll Love This Recipe

This dessert is the definition of hands-off comfort food. With just three main ingredients, it is budget-friendly, forgiving, and perfect for busy holidays or potlucks when you want something warm without a lot of fuss.

The flavors are pure autumn. Warm spice, buttery sweetness, and tender sweet potatoes come together in a way that feels both nostalgic and indulgent.

It is also wonderfully versatile. You can dress it up with pecans, marshmallows, or a caramel drizzle, or keep it simple and let the sweet potatoes shine.

Ingredients

2 cans (29 ounces each) sweet potatoes or yams in syrup, undrained
1 box (15.25 ounces) spice cake mix
½ cup unsalted butter, melted

Optional: chopped pecans, mini marshmallows, or a drizzle of caramel sauce for topping.

Directions

Lightly grease the inside of a 4- to 6-quart slow cooker.
Pour the sweet potatoes with their syrup into the bottom of the slow cooker and spread them into an even layer.
Sprinkle the dry spice cake mix evenly over the sweet potatoes. Do not stir.
Drizzle the melted butter evenly over the top of the cake mix.
Cover and cook on LOW for 3 to 4 hours, or on HIGH for 1½ to 2 hours, until the topping is set and the sweet potatoes are bubbly underneath.
If using marshmallows or pecans, sprinkle them over the top during the last 20 minutes of cooking.
Let rest for 10 minutes before serving.

Variations

Pecan Praline Cobbler: Sprinkle ½ cup chopped pecans over the topping before cooking.
Marshmallow Topped: Add 1 cup mini marshmallows during the last 20 minutes for a gooey finish.
Caramel Drizzle: Warm ¼ cup caramel sauce and drizzle over each serving.
Brown Sugar Boost: Sprinkle ¼ cup packed brown sugar over the sweet potatoes before adding the cake mix.
Butter Pecan Version: Use a butter pecan cake mix for a richer flavor.
Individual Servings: Divide the layers among ramekins and bake at 350°F for 25 to 30 minutes.

Expert Tips

Don’t stir the layers: Leaving them undisturbed lets the topping bake into a tender crust while the sweet potatoes create a syrupy base.
Use spice cake mix: It brings the warm cinnamon and nutmeg flavor without any extra measuring.
Watch the moisture: If the cobbler looks too wet, leave the lid slightly ajar for the last 20 minutes.
Rest before serving: The juices thicken as it sits, giving you a syrupy, spoonable dessert.
Serve warm: This cobbler is best enjoyed warm, when the topping is soft and the sweet potatoes are gooey.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a 325°F oven with a splash of water to loosen. This cobbler does not freeze well, as the topping can become mushy upon thawing.

Frequently Asked Questions

Can I use fresh sweet potatoes?Yes, but you will need to cook them first and add about 1 cup of liquid or syrup for the cobbler to work.
Can I use a different cake mix?Yes. Yellow, butter pecan, or vanilla cake mix all work well.
Why is my cobbler dry? The cake mix may have absorbed too much liquid. Add a splash of water or melted butter and cook for another 15 minutes.
Can I make this in the oven? Yes. Bake at 350°F for 35 to 40 minutes until the topping is golden.
Can I double this recipe? Yes. Use a 6- to 8-quart slow cooker and add 30 to 45 minutes to the cook time.
