Cream together butter and sugar until light and fluffy.
Add in egg and vanilla and mix until combined.
In a separate bowl combine dry ingredients and mix to combine.
Slowly add flour mixture to butter mixture, mixing well between each addition.
The dough should not be sticky and should not be crumbly. If it is sticky, mix in flour one tablespoon at a time until it becomes not sticky. If the mixture is crumbly, mix in water one teaspoon at a time until the dough holds together.
Mix cinnamon, nutmeg and sugar together and place in a shallow bowl.
Scoop balls of dough about the size of a walnut. Roll each ball in the cinnamon sugar mixture, then place on a cookie sheet lined with a silicone liner or parchment paper.
Bake at 350 degrees F for 12-15 minutes or until the center is just set.
Let cool 2 minutes then place on a wire rack to finish cooling.
