Ingredients
Here’s what you will need for the most delicious Sweet Potato Dump Cake:
- 2 cans (29 ounces each) sweet potatoes in light syrup, drained: Look for quality brands like Libby’s for the best flavor.
- 1 can (12 ounces) evaporated milk: This adds creaminess. Avoid substitutes like almond milk for a rich texture.
- 3/4 cup (150 g) light brown sugar, packed: This gives your cake its sweet contrast and moisture.
- 3 large eggs, room temperature: Room temperature eggs blend better and provide a fluffier texture.
- 2 teaspoons vanilla extract: Pure vanilla extract is preferable over the imitation for a more aromatic flavor.
- 2 teaspoons pumpkin pie spice: A warm spice blend that elevates the sweet potatoes beautifully.
- 1 package (15.25 ounces) yellow cake mix: You can use your favorite brand or even a gluten-free option if needed.
- 1 cup (113 g) chopped pecans, plus more for topping (optional): I love to use Diamond nuts for their fresh crunch.
- 3/4 cup (1 1/2 sticks / 170 g) unsalted butter, melted: Using unsalted ensures you control the saltiness of your cake.
- Whipped cream for topping: A heavenly touch before serving!
Prep Notes: Make sure your butter is melted and slightly cooled before mixing. Room temperature eggs emulsify better in the batter, contributing to the cake’s tenderness.

Step-by-Step Instructions
Preheat your oven to 350 degrees F (175 degrees C). I find that this step is crucial in achieving that perfectly baked cake.
Prepare the baking dish: Spray a 9×13-inch baking dish with nonstick spray to ensure easy removal after baking.
Mash the Sweet Potatoes: In a large bowl, mash the sweet potatoes until smooth. The aroma will instantly make your kitchen feel homey!
Combine the Mixture: Add the evaporated milk, brown sugar, eggs, vanilla extract, and pumpkin pie spice to the bowl. Stir until well combined—a wooden spoon works wonders here!
Pour into the baking dish: Spread the sweet potato mixture evenly in the prepared dish.
Sprinkle the Cake Mix: Carefully dust the yellow cake mix over the sweet potato layer in an even manner.
Top with Pecans: Sprinkle chopped pecans over the cake mix for that lovely crunch.
Butter the Topping: Slice the melted butter into small pats and distribute it evenly over the top of the cake mix.
Bake: Place in the preheated oven and bake for 85-90 minutes, or until the top is golden brown and set. To check for doneness, insert a toothpick into the center; it should come out clean.
Cool and Serve: Allow the cake to cool for about 15 minutes before serving. Top each slice with a dollop of whipped cream and additional pecans if desired.
Chef’s Tips:
- Don’t rush the cooling process! Giving it time will enhance the flavors.
- Make sure the oven is fully preheated before baking; this ensures a good rise.
Be mindful of potential pitfalls; overmixing can lead to a dense cake, so stir gently.

Expert Tips & Tricks
Storage Recommendations: Once cooled, store leftovers in an airtight container. It keeps well for up to four days in the refrigerator.
