Incredible Gluten Free Butter Cookies

• 1 cup glutinous-rice flour
• 2/3 cup cornstarch
• 1 1/3 cups almond flour
• 1/4 cup teff flour
• 1 1/3 cups light cane sugar
• 1/2 cup coconut flour
• 200 g butter
• 2 teaspoons vanilla sugar
• 1/4 teaspoon salt
• 2 teaspoons xanthan gum
• 4 egg yolks

1. Preheat oven to 350 degrees
2. In a large bowl sift rice flour, corn starch, almond flour and teff.
3. Grind coconut flour TOGETHER with cane sugar until fine, add to flour mixture.
4. Add xanthan gum, salt and vanilla sugar and mix all ingredients well, using a wire whisk.
5. Cut in butter and egg yolks and knead until you have a nice supple dough. At first it may seem the dough won't come together, but don't panick: it will ;-).
6. Shape cookies the way you prefer.
7. If dough is a bit too stiff for using a cookie press add a little cold water (no more than one tbsp at a time!)
8. Place cookies on a greased cookie sheet or silpat leaving 1/2 inch in between.
9. Bake for 15-20 minutes, remove from oven when they start to smell real good and just turned slightly golden.
