Preheat oven to 400º Fahrenheit. Line a baking sheet with parchment paper.
In a medium mixing bowl, whisk together the almond flour, ground flax seeds, xanthan gum, baking powder, salt.
Cut the butter into the dry ingredients using a pastry blender. Mixture should appear mealy.
In a small bowl, whisk together the sour cream and the egg white. Stir this mixture into the dry ingredients.
Transfer mixture to a piece of parchment paper. Shape into a disk about 1/2 inch thick. Cut into desired shapes and place each biscuit onto the prepared baking sheet, allowing at least 2 inches between biscuits.
Bake biscuits in the preheated oven for about 10-12 minutes. Larger shapes will take longer.
