Pre-heat oven to 350 degrees. Prepare baking sheets with non-stick cooking spray or parchment paper.

In a stand mixer, beat sugar and butter until smooth.

Beat in egg whites (or 1 egg), vanilla and chickpeas. Mix to your liking for the chickpea consistency.

In a separate bowl, mix together: flour, oats, baking soda and salt.

Add the dry ingredients to the butter mixture and mix on low speed until a thick dough forms.

Add the chocolate chips, and other optional ingredients.

Drop the dough by rounded tablespoons onto baking sheets leaving some space between each cookie.

Using a fork, or the palm of your hand, gently flatten the tops of each dough ball.

Bake for 11-13 minutes, or until golden brown. Do NOT overbake.

Transfer to wire rack and cool
