From GlutenFreeGirl.com "GLUTEN-FREE SPRITZ COOKIES, adapted from America’s Test Kitchen Let this be a warning to you: the recipe that comes with the kitchen tools you need to make that recipe? They generally stink. I know that now because I made a big batch of spritz cookies based on the recipe that came with the spritz press I just acquired. It was dry, stiff, and tasteless. And it all went into the trash bin. Danny and I persisted, however. We didn’t want you to miss these buttery, slightly sweet lovely treats. If you’ve made spritz cookies before, and you have a spritz press already, pull it out. It’s not too late to make these little cookies. And, if like me, you have never made these before, and you don’t quite get the hang of the different disks and how to press them down on the baking sheet firmly, you can have little squiggles of cookies that look like piles of noodles! “Pasta cheese!” Lu shouted when she saw these, then ate one. That was pretty great."

Preparing to bake. Preheat the oven to 375°. Line a baking sheet with parchment paper or a Silpat. Combining the dry ingredients. Add the flour, xanthan gum, guar gum, and salt to a bowl. Whisk them together to combine and aerate the flour. Set aside. Combining the wet ingredients. In another bowl, whisk together the egg yolk, yogurt, and vanilla extract. Set aside. Creaming the butter and sugar. In the bowl of a stand mixer, mix the butter and sugar until they are light and fluffy, about 3 minutes. Stop the mixer and scrape down the sides of the bowl. With the mixer running again, add the egg-yogurt-vanilla mixture and beat until it is incorporated into the butter and sugar, about 30 seconds. Slowly, a bit at a time, add the dry ingredients. Mix until the ingredients are combined and form a dough around the paddle. Turn off the mixer and scrape down the sides of the bowl to combine with the dough and make sure there are no pockets of flour left. The dough should be pliable without being too soft, yet not too stiff. Baking the spritz cookies. If you have a spritz cookie press, fill the press with the dough. If the dough feels soft in your hands, refrigerate the cookie press for 15 minutes. Use the directions for your particular cookie press to find the best way to shape the cookies. If you don’t have a spritz cookie press, you can press the dough through a pastry bag, using the tip of your choice. Put the cookies on the baking sheet, leaving two inches between them, until the sheet is comfortably full. Bake until the cookies are light golden brown and set, about 12 to 15 minutes, rotating the baking sheet halfway through. Allow the cookies to cool for 10 minutes, then transfer them to a cooling rack. Eat when there is not a smidge of warmth to the cookies.
