Step 1

Cream together the butter and sugar. Add the eggs and beat again. Whisk together the flour, starch, xanthan, baking soda, cream of tartar and salt. Add the dry ingredients to the wet ingredients and mix to combine. Chill the dough in the refrigerator for at least 1 hour.

Step 2

Preheat oven 400°F. Combine ¼ cup sugar and cinnamon in a small bowl. Scoop the dough into balls and roll in the cinnamon sugar mixture. Place on a silpat or parchment lined baking sheet. Bake for 8 minutes and remove from the oven before the cookies are browned. They should be slightly puffy and crinkled on top. (If you prefer crispy cookies, let cook them a minute or two longer.)

Step 3

Allow them to cool on the baking sheet for 1-2 minutes and then remove to a wire cooling rack. Alternate using two baking sheets to allow each baking sheet to cool completely between batches. Enjoy!
