These gluten free snickerdoodle sandwich cookies pair soft, chewy cinnamon sugar cookies with creamy cinnamon cream cheese frosting. A fun twist on a classic cookie, perfect for holiday baking or sharing with friends!
In a large bowl, beat the butter and sugar for 2–3 minutes, until light and fluffy. Beat in the egg and vanilla, scraping down the bowl as needed.
In a separate bowl, whisk together the gluten free flour, almond flour, cream of tartar, cinnamon, baking soda and salt.
Add to the butter mixture and mix just until combined. Cover and refrigerate for 30 minutes.
While the dough chills, preheat the oven to 350°F and line two baking sheets with parchment paper.
In a small bowl, stir together the sugar and cinnamon for the coating.
Divide the dough into 16 equal portions, about 2 Tablespoons each. Roll into balls, coat generously in cinnamon sugar and place 8 on each baking sheet, about 3 inches apart. Gently press each ball into a thick disk, about ½ inch tall.
Bake for 12–14 minutes, until the edges are set but the centers still look slightly soft. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Once the cookies are cool, make the frosting: beat the cream cheese and butter in a bowl until smooth. Add the powdered sugar, vanilla, cinnamon and salt, then beat until light and creamy.
Pair up cookies of similar size. Spread or pipe frosting onto the flat side of 8 cookies, then top with the remaining cookies, flat sides down. Start with about 2 Tablespoons of frosting per sandwich and add more as desired.
Notes
Gluten free flour: I only tested this with Bob's Red Mill gluten free 1 to 1 all purpose flour. Any 1 to 1 blend that contains xanthan gum should work, but I haven't tried other brands.
Measuring: For best results, weigh the flours. Gluten free dough is sensitive to too much or too little flour.
Chilling: Don't skip the 30 minute chill. It keeps the cookies thick and makes the dough easier to roll.
Storage: Store assembled cookies in an airtight container in the fridge for up to 4 days. Don't leave them at room temperature for more than 2 hours.
Make ahead: Unfrosted cookies can be frozen for up to 3 months. Thaw, then frost and sandwich.
