Process the almonds and sweetener in the food processor for 5 minutes, scraping down the sides occasionally. Add the egg whites. Process until it comes together and is about the consistency of peanut butter.
Put the pine nuts in a shallow bowl. Drop tablespoons of the dough into the pine nuts. Roll the balls of dough around covering them with nuts. Place on a parchment lined baking sheet.
Bake for 20-25 minutes until slightly golden. Cool completely and dust with finely ground sweetener, if desired.
