Ingredients
To ensure you achieve that perfect blend of flavor and texture, here’s what you’ll need:
- 4 large sweet potatoes (about 2 pounds)–packed with antioxidants and vitamin A.
- 1/2 cup unsalted butter–provides smoothness and richness.
- 1/2 cup brown sugar–deepens the flavor with its molasses content.
- 1/4 cup milk–for creaminess. Use almond milk for a dairy-free option.
- 1 teaspoon vanilla extract–adds aromatic depth.
- 1/2 teaspoon ground cinnamon–complements the sweetness.
- 1/4 teaspoon ground nutmeg–for a warm, spicy kick.

Ingredient Science: Sweet potatoes are a fantastic source of complex carbohydrates, making this a filling addition to your meal. Combining the natural sugars of sweet potatoes with brown sugar gives the dish a deeper flavor profile without overwhelming sweetness. The dash of salt is crucial, enhancing overall flavor by balancing sweetness.
