Grab a medium-sized bowl and whisk together your oats, flour, cinnamon, baking soda, nutmeg, and salt until everything's evenly mixed. Set this bowl aside for now.
02 -
In a larger bowl, beat the softened butter with the brown sugar using a hand mixer or wooden spoon until you get a smooth, creamy mixture.
03 -
Crack in the egg, then add your mashed sweet potato and vanilla extract. Mix everything together until well blended and no streaks remain.
04 -
Pour your dry ingredient mixture into the wet ingredients and stir gently until just combined. Fold in the chocolate chips throughout the dough.
05 -
Cover your bowl with plastic wrap and pop it in the fridge for at least an hour. This helps the cookies hold their shape when baking. You can even leave it overnight if you're planning ahead.
06 -
Heat your oven to 350°F (or 160°C if using a fan oven). Line three baking trays with parchment paper or silicone mats.
07 -
Using a small cookie scoop (about 1½ to 2 tablespoons), drop balls of dough onto your prepared trays, spacing them about 2 inches apart. If you like, press a few extra chocolate chips on top of each cookie for a prettier finish. Bake for 9 to 11 minutes until they puff up and turn light golden around the edges.

Let the cookies rest on the baking sheet for about 5 minutes, then carefully move them to a cooling rack to finish cooling completely.
