In a large bowl cream together the butter, ⅓ cup erythritol and vanilla until well combined.
Slowly add the almond flour and mix together with a rubber spatula.
Using your hands knead the dough until moist enough to form 1 inch balls.
Combine the pork rind crumbs and the erythritol.
Roll each cookie dough ball through the pork rind mixture and place on a parchment lined baking sheet.
Bake at 350°F for 12 minutes. Cookies should be lightly golden on the outside. (Refer to the detailed video instructions below if further clarification is needed)

Notes
Pro Tip: continue to knead the dough with your hands until it becomes moist enough to roll into cookie dough balls. It may appear crumbly at first, kneading for about a minute will bring it together.
