Preheat oven to 350 degrees F.

Place all the ingredients EXCEPT for chocolate chunks into a mixing bowl.

Beat until well combined, about 1-3 minutes. Mixture should look like a thick, glossy frosting. I recommend using a stand mixture or beaters because this can be a thick batter. Start by adding in 3 egg whites. If the batter is too thick, feel free to add in a 4th egg white. It should resemble brownie-like batter consistency.

Stir in chocolate until combined.

Scoop cookie dough onto a parchment lined sheet pan. I used a 2” cookie scoop for this step.

These cookies spread quite a bit, so I wouldn’t recommend putting more than 6 cookies on one pan at a time.

Bake cookies for 11-13 minutes or until tops are cracked and shiny.

Let cookies cool completely before removing them from pan, about 5-10 minutes. Enjoy!
