Set oven to 350F
Whisk the egg and sugar together until well blended. Beat in the baking soda and cashew butter and then fold in the chips.
I use a 1 1/2 inch cookie scoop to scoop out balls of dough. Space them 2 inches apart on a parchment lined baking sheet.
Flatten the balls of dough just slightly with your fingers or a spreading knife.
Bake for about 12-13 minutes. The cookies will puff up and just barely begin to get golden on the edges. They will look soft and a little under done, but will firm up as they cool.
Cool the cookies for a few minutes on the pan, then transfer to a rack.
