Preheat oven to 375°F. Line two cookie sheets with parchment paper.
In a large mixing bowl, mix together the butter, coconut sugar, and vanilla extract.
Add the rest of the ingredients and stir until combined. You should be able to handle the dough without it sticking to your hands. Divide the dough in half.
Prepare two pieces of waxed parchment paper and sprinkle tapioca flour on one piece. Place half of the dough on the floured wax paper and flatten the dough slightly.
Using a rolling pin, roll out the dough until it is a little over an 1/8 of an inch thick. Peel pack the top layer of wax paper and use cookie cutters to make the cookies.
Transfer the cookies to the cookie sheets with a metal spatula. Continue the process until all the dough is used up.
Bake standard size cookies for 7-8 minutes. Allow them to cool before frosting.
Frosting
Beat together all of the frosting ingredients. Add more coconut milk if the frosting is not smooth enough. Enjoy frosting the cookies!
