Gluten-Free Chocolate Crinkle Cookies

In a large bowl, whisk the flour, cocoa powder, baking powder, baking soda, and salt. Set aside. In a separate bowl, add the butter and sugar and beat with a hand mixer for 1-2 minutes until fluffy. Then, add the eggs and vanilla and beat again. Slowly mix in the dry ingredients. Cover and refrigerate the dough for at least 2 hours. Preheat oven to 350°F. Line a baking sheet with parchment paper. Roll a little over a tablespoon-size of dough in the confectioners sugar. Bake for 11-12 minutes and let cool on the baking sheet for about 2-3 minutes.
