Mix together well the remainder ½ cup sugar, cinnamon, and cardamom.
Roll the 1-inch ball in the sugar, cinnamon, and cardamom mixture.
Space about 2 inches apart on the cookie sheet and bake (one sheet at a time) until the cookies are golden brown at the edges, about 8 to 9 minutes.
Remove the sheet from the oven and let it cool off until the cookies are firm. Transfer to a cookie rack.
Let the cookie sheet cool off completely between batches, or the cookies will cook too fast.
Notes
PRO TIPS
Do not overbake the snickerdoodle. They will still need to be soft when they cool as they continue to harden once they are out of the oven.
Once you have added the dry ingredients to the wet ingredients, do not overmix. Overmixing the flour will cause the gluten to overdevelop and give you a flat, hard cookie.
If you use only one cookie sheet, let it cool off completely before adding another batch of cookies. The heat of the sheet will start the baking process and render a flat cookie.
