Whisk the dry ingredients in a large bowl. Add vinegar and egg whites to the dry ingredients, and combine well. Add boiling water and beat with a hand mixer for about 30 seconds or until the mixture resembles playdough. Shape dough into 6 separate buns and place on a parchment-lined baking tray.
Bake 50 to 60 minutes. If you hear a hollow sound by tapping the tops, the keto buns are done.
The Culinary Chase’s Note: To make hamburger buns, divide the dough into 4 and cook for the same length of time. Enjoy!
