How to make
Mix all the products, except the biscuit, in a bowl and mix well until a homogeneous mixture is obtained.
Crumble part of the biscuit into the mixture and mix again.
From the resulting mixture, we form a cookie in a plate on baking paper and crush the rest of the biscuit.
Bake the cookie in the microwave for 1-2 minutes or until done (if desired the cookie can be baked in the oven).
Enjoy the protein cookie while it's still warm with a cup of coffee!
*If necessary, add more flour/milk depending on the consistency obtained.
