Preheat your oven to 375°F (190°C) and prepare baking sheets with parchment paper.

Cream together softened butter, granulated sugar, and brown sugar in a mixing bowl for 3-5 minutes until light and fluffy.

Mix in the egg and vanilla, then fold in the mashed sweet potato until smooth.

Whisk together flour, baking soda, cinnamon, nutmeg, and salt in a separate bowl.

Gradually add the dry mixture to the wet ingredients, mixing on low speed until just combined.

Fold in chocolate chips until evenly distributed throughout the dough.

Scoop rounded spoonfuls of dough onto prepared baking sheets, leaving space for spreading.

Bake for 10-12 minutes until edges turn golden and centers are slightly soft.
