Step 1: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone mat.
Step 2: Separate the egg whites from the yolks. In a large bowl, whip the egg whites with a hand mixer until stiff peaks form.
Step 3: In a separate medium bowl, mix the egg yolks and softened cream cheese until smooth and well combined.
Step 4: Stir the ground pork rind crumbs into the yolk and cream cheese mixture until a thick paste forms.
Step 5: Gently fold one-third of the whipped egg whites into the pork rind mixture to lighten it up.
Step 6: Carefully fold in the remaining egg whites, being careful not to deflate the mixture, until no white streaks remain.
Step 7: Scoop the batter onto the baking sheet in 6 equal rounds, smoothing the tops slightly with the back of a spoon.
Step 8: Bake for 18-20 minutes or until the buns are golden brown and spring back when lightly touched.
Step 9: Remove from the oven and allow to cool completely on the pan before attempting to remove or slice.
