These Valentine heart sugar cookies are made with no-chill, no-spread cookie dough that makes delicious cookie sandwiches paired with raspberry buttercream.
Make the cookie dough. Place flour, both sugars, salt, baking soda, and cream of tartar in a food processor and process just until mixed.
Roll the dough to ¼ inch thickness. Cut 16 cookies using a 3 ½ inch heart shaped cookie cutter. Cut a smaller heart in half of the cookies using a 2 inch heart-shaped cookie cutter.
