In a medium bowl, whisk together the almond flour, coconut flour, vanilla protein, baking powder, and salt.
In a separate bowl, beat the butter and stevia until creamy.
Add in the egg, egg yolk, and vanilla extract and blend until creamy.
Slowly add the remaining dry ingredients to the mixture and blend until you have a smooth and firm dough.
Wrap dough in plastic wrap and leave in the fridge for 30 min.
Preheat oven to 325°F and line a baking sheet with parchment paper.
Remove dough from fridge and roll out to 1/4″ thick.
Note: If the dough has warmed, place the cookie sheet in the fridge for another 10 minutes. If the dough is too sticky, oil the rolling pin before rolling out.
Cut dough into desired shapes and place cookies 1" apart on parchment paper.
Bake until the cookies are beginning to brown around the edges (approximately 10-15 minutes).
Remove cookies from oven and place and allow to cool before frosting.
While the cookies are cooling, mix coconut butter and protein powder in a small bowl and then add to piping bag.
Decorate cooking as desired.
