Add all ingredients to a Vitamix blender. Mix well on setting 3 until mixture forms a ball.
Place dough ball in parchment paper and let sit in the refrigerator for about 45 minutes. This allows the dough to firm up so it's easier to work with.
Pre-heat oven to 350°F/180°C.
Sprinkle table top or large cutting board with 1-2 tbsp (or more as needed) tapioca flour.
Remove dough from refrigerator and place on dusted cutting board. Dust rolling pin and start rolling out dough until it's very thin - about 1/8 inch thick (or about the thickness of 2 pennies stacked together).
Use cookie cutters to cut out shapes. Keep dusting surface and rolling pin as needed.
Line a baking sheet with parchment paper. Place cookies on top - about 2 inches apart.
Bake for 6-8 minutes - or until the edges of the cookie are browned and center is firm.
Let cool on a wire rack for at least 10 minutes. Use your favorite frosting to decorate as desired.
