Using a rubber spatula, scrape down the sides of the bowl. Add flour, cornstarch, baking soda, and salt. Turn the hand mixer to a low speed and combine the ingredients until a soft dough forms.
Cover the bowl with plastic wrap and place in the refrigerator for 2 hours.
Once the dough has been chilled for 2 hours, remove from the refrigerator and preheat the oven to 350 degrees F. Line a baking sheet with parchment paper and set aside.
Place the balls on the parchment paper lined cookie sheet, at least 1 inch apart.
Using a fork, make a criss cross pattern pressing down lightly into the cookie dough.
Sprinkle with green or red sugar.
Red & Green Sanding Sugar
Bake in the oven at 350 degrees F for 9-11 minutes. Make sure not to overcook these cookies, they should not brown on the edges at all. You want them to be soft, and they should look a bit undercooked when you pull them out of the oven.
Let cookies cool on the baking sheet for 5 minutes before removing to a wire rack to continue cooling.
Notes
Storage :
Store: Keep cookies in an airtight container at room temperature for 5-7 days.
Reheat: Microwave for 5-10 seconds if you like them warm and soft.
Freeze: Store baked cookies in a freezer-safe container for up to 3 months. Thaw at room temp before serving.
Make Ahead: Dough can be prepared 2-3 days in advance and kept in the fridge, or frozen for up to 3 months.
Tips:
Soften butter and cream cheese fully before mixing to avoid lumps.
Remove cookies slightly underbaked; they’ll firm up as they cool.
Use a cookie scoop for even sizes and perfectly round cookies.
Line pans with parchment or silicone mats for easy cleanup.
