  • Total Time: 1 hour 20 minutes
  • Yield: 6 servings

Ingredients

3 medium sweet potatoes

1/4 cup softened butter

1/4 cup light brown sugar

1/4 cup milk

1 egg

1/2 teaspoon vanilla extract

For the topping:

1/4 cup light brown sugar

1/4 cup chopped pecans

1 tablespoon all-purpose flour

1 tablespoon softened butter

Instructions

  1. Rinse the sweet potatoes and place them in a pot with water covering by about 1 inch. Bring to a boil, reduce heat, and simmer for 40–45 minutes until very tender.
  2. Remove sweet potatoes and let them cool enough to handle. Slice open to speed cooling.
  3. Preheat oven to 350°F and butter a baking dish.
  4. Peel the sweet potatoes, mash them in a bowl, then add butter, brown sugar, milk, egg, and vanilla.
  5. Beat the mixture with an electric mixer at medium speed until smooth.
  6. Spread evenly into the buttered baking dish.
  7. In a small bowl, combine brown sugar, pecans, flour, and butter. Mix with a fork until crumbly.
  8. Sprinkle topping evenly over the sweet potato mixture.
  9. Bake for 30 minutes at 350°F until golden and bubbly.

Notes

Swap pecans with walnuts, almonds, or shredded coconut for variety.

Add mini marshmallows on top for a sweeter version.

Prepare the base ahead and store the topping separately to assemble later.

Store leftovers in the fridge up to 4 days or freeze up to 3 months.

Bake uncovered to keep the topping crunchy.
