Preheat the oven at 350°F.
Combine butter and sugar until light colored and fluffy (this can take about 10 minutes in a stand mixer on low to medium speed).
Mix in one egg and vanilla essence.
In a separate bowl, mix dry ingredients like flour, baking soda, salt, cinnamon and nutmeg powder.
Reduce the speed in the stand mixer and add the dry ingredients to the batter.
Incorporate fully.
Stop the mixer.
Fold the chocolate chips into the batter.
Place a tablespoon of the batter onto a baking tray.
Repeat placing others two inches apart in either direction (I do six small cookies per tray).
Bake for 10 to 12 minutes.
Repeat for other baking trays.
Remove each batch from the oven.
Place on a cooling rack to cool down (or leave for 5 minutes, then turn over and allow the steam to dissipate to prevent softening of the cookies).
Serve immediately or store in the fridge or freeze.
