Decorated gluten-free sugar cookies are fast and easy to make using a food processor to mix the cookie dough.
- 1 1/2 cups flour (all-purpose gluten-free)
- 1/2 cup tapioca flour (OR potato starch)
- 1 cup powdered sugar (gluten-free)
- 1 teaspoon guar gum (OR xanthan gum)
- 1 teaspoon cream of tartar
- 1/8 teaspoon salt
- 1 cup butter (cold, cut into small pieces)
- 1 egg
- 1 tablespoon milk (OR canned coconut milk)
- 1 teaspoon vanilla extract (OR lemon extract, if you like lemony sugar cookies)
- 1 tablespoon lemon peel (freshly grated)
- 4 cups sugar (gluten-free, powdered)
- 2 tablespoons milk (OR canned coconut milk)
- 1 teaspoon honey (OR corn syrup)
- Optional: Food coloring
Preheat oven to 350 F / 176 C
Line baking sheets with parchment paper, Silpat mats or lightly grease with vegetable shortening.
Put all dry cookie ingredients in a food processor and pulse about 3 times to thoroughly blend. If you aren't using a food processor place the ingredients in a large mixing bowl and whisk until thoroughly combined.
Add pieces of butter and pulse about 10 times. If using an electric mixing beat on high for about 1 minute.
Add egg, 1 tablespoon of milk, lemon extract and peel and pulse about 5 times. The mixture should form a sticky, stiff dough. If the dough is too dry, gradually drizzle in more milk. You don't want the dough too sticky or it will be harder to roll out.
Wrap the dough in waxed paper and refrigerate for at least 2 hours or overnight before rolling and cutting out cookies.
Lightly flour a large sheet of waxed paper with sweet rice flour and roll the dough to about 1/8-inch thickness. Try to roll the dough evenly so cookies will bake evenly.
Use your favorite cookie cutters and dip in rice flour for easier cutting.
If the dough softens too much while cutting the cookies, place the dough on the waxed paper on a baking sheet and freeze it for several minutes and then continue.
Bake in a preheated oven for about 12 minutes or just until the edges of the cookies turn golden brown.
While cookies are baking prepare sugar cookie icing by whisking all icing ingredients until smooth. The goal is to add just enough milk for a spreadable consistency. Add milk gradually. If the icing gets too thin, add more powdered sugar, 1 teaspoon at a time. To decorate with different colors, divide the icing between bowls and add a few drops of food coloring, one at a time until you get the color you want. Stir until smooth.
Cool cookies completely before decorating with prepared icing.
Store in an air-tight container or wrap tightly and freeze for a make-ahead holiday convenience.
