1. Prepare the Crust:

1. Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. In a large bowl, cream together the butter and honey until smooth. Add the mashed sweet potato, egg, and vanilla extract, mixing well.
3. In a separate bowl, whisk together the flour, baking powder, cinnamon, nutmeg, and salt.
4. Gradually add the dry ingredients to the wet mixture, stirring until just combined.
5. Drop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them about 2 inches apart.
6. Bake for 12-15 minutes or until the edges are lightly golden. Let cool on the baking sheet for 5 minutes before transferring to a wire rack.
