7. To make keto royal icing, combine 1 cup powdered erythritol sweetener, egg whites, cream of tartar, and salt in a small bowl. Whisk until smooth. Remove 1/3 of the icing into a smaller bowl and add remaining 1/4 cup powdered erythritol. Whisk until slightly thicker than original icing mixture. Use the first batch of icing to flood the inside of the cookies with icing and the second thicker batch to outline the cookie. Add icing batches to two separate piping bags. Using the thicker icing, pipe the borders of your cutout cookie. Then using the thinner icing, flood the inside of the outline.
