Ingredients

Always use the highest quality ingredients for the best results. Here’s what you need to make a delectable Sweet Potato Dump Cake:

2 cans (29 ounces each) sweet potatoes in light syrup, drained (I love using Libby’s for its rich flavor)
1 can (12 ounces) evaporated milk
3/4 cup (150 g) light brown sugar, packed
3 large eggs, room temperature (take them out a bit earlier for an even texture)
2 teaspoons vanilla extract
2 teaspoons pumpkin pie spice (or make your own blend for a personal touch)
1 package (15.25 ounces) yellow cake mix (Duncan Hines or Betty Crocker work great)
1 cup (113 g) chopped pecans, plus more for topping (optional if you’re nut-free)
3/4 cup (1 1/2 sticks / 170 g) unsalted butter, cut into pats
Whipped cream, for topping (because what’s a dessert without a little decadence?)

Prep Notes

It’s important to let the butter come to room temperature; it mixes better and creates a more uniform texture.
Feel free to substitute sweet potatoes with fresh ones, just boil and mash them first; you’ll need about 3 cups.

Step-by-Step Instructions

Preheat and Prep: Preheat your oven to 350 degrees F. Spray a 9×13-inch baking dish with nonstick spray (trust me, you don’t want this cake to stick!).
Mash the Sweet Potatoes: In a large bowl, add your drained sweet potatoes and mash them until smooth. No need for perfection—some lumps add to the rustic charm!
Mix Wet Ingredients: To the mashed sweet potatoes, add the evaporated milk, brown sugar, eggs, vanilla extract, and pumpkin pie spice. Stir until everything is well combined and creamy.
Pour and Layer: Pour this luscious sweet potato mixture into your prepared baking dish, spreading it evenly.
Cake Mix Layer: Now, sprinkle the cake mix evenly over the top. Don’t mix it in—this is where the “dump” magic happens!
Nutty Topping: Top the cake mixture with chopped pecans for that wonderful crunch.
Butter Patting: Slice your room-temperature butter into small wedges (about 16), placing them evenly on top of the pecans. This will melt and create that delicious golden-brown crust.
Bake Away: Pop the dish in the oven and bake for 85-90 minutes. Look for a golden brown top; a toothpick inserted in the center should come out clean (add a few more minutes if it’s still wet).
Cooldown: Remove the cake from the oven and let it cool for at least 15 minutes. It’s hard to resist, I know, but giving it time to set will make serving easier.
Serve and Enjoy: Serve warm topped with a dollop of whipped cream and extra pecans for that final touch of decadence!

Expert Tips & Tricks

1. Storing Leftovers: Store any leftover cake in an airtight container in the fridge for up to 5 days. It can be served cold, but I prefer it warmed up!

2. Make Ahead: You can prepare the sweet potato mixture ahead of time and store it in the fridge for a day. Just add the cake mix and pecans right before baking.

3. Troubleshooting: If your cake is too dry, it may have baked too long; next time, check it at 80 minutes. Conversely, if it’s too moist and sinks, ensure your sweet potatoes are well-drained.

4. Serving Size: This recipe typically yields around 12-15 generous servings. Perfect for gatherings, but be prepared for people asking for seconds!

Serving Suggestions

Pair this Sweet Potato Dump Cake with a scoop of vanilla ice cream or serve alongside caramel sauce for a delightful contrast. Presentation-wise, a sprinkle of cinnamon or extra pecans on top boosts aesthetics! It’s perfect for Thanksgiving, rustic family gatherings, or even as a cozy treat on a chilly afternoon.

Variations & Substitutions

Flavor Combinations: Try swapping out sweet potatoes for canned pumpkin for a delicious change or mix in chocolate chips for a festive twist.
Dietary Adaptations: To make it gluten-free, look for a gluten-free yellow cake mix. For a dairy-free option, use coconut milk in place of evaporated milk and a dairy-free butter substitute.
Seasonal Variations: During the fall, incorporate spices like nutmeg or allspice, or use fresh cranberries for a tartness that balances the sweetness perfectly.
