Servings

Ingredients

2 15-ounce cans sweet potatoes in light syrup, drained
1/2 cup salted butter melted
1 14-ounce can sweetened condensed milk
1 tablespoon vanilla extract
1 tablespoon pumpkin pie spice
1 2-layer size spice cake mix or yellow cake mix
1/2 cup salted butter cold and cut into small pieces
1/2 cup chopped pecans optional
Whipped cream or vanilla ice cream for serving (optional)

Instructions

Preheat the Oven and Prepare the Pan:

Preheat the oven to 350°F (180°C). Grease a 9x13-inch baking dish thoroughly with butter or nonstick spray and set aside.

Prepare the Sweet Potato Base:

In a large mixing bowl, combine the drained sweet potatoes, melted butter, sweetened condensed milk, vanilla extract, and pumpkin pie spice. Using an electric mixer on medium speed, beat the ingredients together until mostly smooth, allowing for a few small chunks of sweet potato to remain.

Assemble the Cake:

Spread the sweet potato mixture evenly into the prepared baking dish. Sprinkle the dry cake mix evenly over the sweet potato layer without stirring. Distribute the cold butter pieces evenly over the top of the cake mix. If using, scatter the chopped pecans over the surface.

Bake:

Transfer the dish to the preheated oven and bake for approximately 45 minutes, or until the top is golden brown and the filling is set.

Cool and Serve:

Allow the cake to cool in the pan for at least 20 minutes before serving. Top with whipped cream or a scoop of vanilla ice cream if desired.

Notes

To prepare a gluten-free version of this Sweet Potato Dump Cake, substitute the regular cake mix with a certified gluten-free yellow or spice cake mix. Verify that all other ingredients, particularly the sweetened condensed milk and flavorings, are labeled gluten-free to ensure the dish remains safe for those with gluten sensitivities.
