Prepare Cookie Dough
Preheat oven to 350F while you prepare your dough. Prepare 1 or 2 baking sheets lined with parchment paper or a silicon baking mat.
Combine cashew butter, cane sugar, maple syrup, vanilla extract and flax egg and cream until smooth, using a spatula.
Sift in oat flour, almond flour, spice mix, baking soda, cream of tartar and salt, and stir again until a dough forms. Dough should be slightly sticky but workable. You can refrigerate it for 10-15 minutes to help it firm up if needed.
Prepare sugar spice mix
In a small bowl, whisk together cane sugar, cinnamon and chai spice mix until evenly incorporated.
Bake cookies
Scoop dough using a cookie scoop or tablespoon and roll into balls. Gently roll the ball in the sugar spice mix to coat, then gently press into cookie shapes on your baking mat. Give cookies at least 1 1/2" space between each other as they will spread just a bit.
Bake cookies for 10-13 minutes, until edges are golden brown. Cookies will firm up once removed from the oven, so if you prefer a chewy cookie, pull them out around the 10-11 minute mark. If you prefer a crispier cookie, feel free to bake for additional time as needed.
Let cool for at least 10 minutes before gently removing from the baking tray (so they don't fall apart) and enjoy!
