Gluten-Free Spicy Hot Chocolate Cookies

In small bowl, whisk together white rice flour, potato starch, cocoa, ground chipotle, baking powder, salt, and xanthan gum. In bowl of stand mixer fitted with paddle attachment, cream together butter and granulated sugar on medium speed until thick paste forms, about 30 seconds. Stop mixer. Scrape down bottom and sides of bowl.

Add egg. Cream on medium speed until light and thoroughly combined, about 30 seconds. Stop mixer.

Add dry ingredients.

Mix on medium-low speed until dough forms, about 2 minutes. Dough will be dry. If after two minutes, dough does not form, add one teaspoon milk.

Turn dough out onto floured work surface. Pat into a disk. Wrap tightly with plastic wrap. Chill two hours or overnight.

Adjust oven rack to middle position. Preheat oven to 350°F. Line rimmed baking sheet with parchment paper. Dust work surface lightly with white rice flour.

Roll dough out to 1/8-inch thickness.

Cut into shapes. Use a cookie spatula and transfer dough to prepared baking pan. Space cookies 1-inch apart on pan.

Bake until cookies are aromatic and firm, about 12 minutes for 3-inch cookies.

Remove pan from oven. Allow cookies to cool on pan for 1 minute before transferring to wire rack. Gather scrapes of dough. Re-roll and repeat until all dough is used. Store cooled cookies in an airtight container for up to one week.
