Start by adding the butter (room temp), powdered sugar, almond extract, and vanilla extract to the bowl of your stand mixer. Turn the mixer on low for about 10 seconds and then increase the speed to medium low.
Allow it to mix for 2 minutes and then increase the speed to medium/high for an additional minute. Turn off the mixer and scrape the sides of the bowl.
Preheat the oven to 325ºF.
Add the xanthan gum, flour, tapioca starch, and salt with the mixer on low. Blend on medium low for 1 minute and then scrape the sides. Turn the mixer on for an additional minute on medium low.
Use a cookie scooper (I recommend a small size scooper) to get a ball of dough, roll it in your hands and slightly flatten it. Then drop it in your desired color of Watkins decorating sugar.
Place it on a baking sheet lined with parchment paper and bake them about 14-16 minutes. The tops should be firm and a little bit of slight cracking is ok.
