Preheat oven to 350°F. Line two baking sheets with parchment paper or silpat mats. Mix almond butter, sugar, flour, and egg in a bowl until smooth dough batter forms. Stir in almonds if using.
Take 2 tablespoons of dough and combine into a smooth ball. Place on cookie sheet. Repeat with remaining dough, spacing balls about 2 inches apart. Bake for 10 minutes. Let cookies cool on cookie sheet before removing. (Note: cookies do spread a lot but they should still remain cookies. If for some reason yours are coming out completely flat, you can try refrigerating the dough for 30 minutes before baking. I did not refrigerate the dough and just baked as is.)
