In large bowl, combine flours, xanthan gum, sea salt + baking powder. Set aside.
In a mixer or using a hand mixer, combine butter + coconut sugar until light and fluffy.
Then add in egg + vanilla extract. Once it is combined, gradually add in dry mixture until a dough forms.
On ungreased cookie trays, roll dough into small balls and use finger or fork to flatten. You can also create shapes if you wish! Option to add just sprinkles at this time or leave them plain.
Bake for about 6 to 8 minutes until edges of cookies are golden brown. Let them cool on wire rack.
Once cooled (about 10 - 15 minutes), cover with icing + sprinkles and enjoy!
Keep in an airtight container for up to 2 weeks.
