To make the chaffles, whip the egg whites with a fork until frothy. Blend in the almond flour and sour cream. Mix well then add the 1/2 cup shredded mozzarella.
Cook the chaffles in a mini waffle maker using half the mixture. Cook until golden brown then set aside.
Top each chaffle with 2 tbsp pizza sauce, 2 tbsp of shredded mozzarella cheese, and all your favorite toppings.
Bake on a sheet pan in a preheated 375-F oven for 5-7 minutes, then turn the broiler on for 2 minutes to get the tops golden brown and bubbly.
Serve!
Notes
Recipe Card Tips
Spread the cheese evenly across the waffle iron before closing the lid, for a more even chaffle.
Skip the salt in the batter. The cheese already provides plenty on its own.
Don't force a sticking lid. Give it another minute before trying to open it again.
The nutritional info includes the chaffles, sauce, and cheese. It does not account for all your toppings. Add the macros for your toppings separately.
