Preheat the oven to 350 degrees F.
Place parchment paper on a baking pan.
In a mixing bowl, combine the egg, Erythritol, almond flour, and vanilla extract, stirring until just mixed.
Gently fold in the cool whip to form a sticky and soft dough.
Spoon the cookie dough onto the tray.
Add crushed nuts or chocolate chips to the cookies.
Bake in the oven for 10 to 12 minutes or until the edges are golden brown.
