Gather all your ingredients. Preheat oven to 340°F (170°C). Line a baking sheet with parchment paper.

Separate the egg yolks from the whites. Add the egg whites and cream of tartar to a clean bowl.

Beat the egg whites until soft peaks form, then gradually add the protein powder while continuing to beat until stiff, glossy peaks form.

Gently fold in the grated parmesan cheese and diced chives into the egg white mixture using a spatula until just combined.

Spoon mounds of the mixture (about 1 tablespoon each) onto the prepared baking sheet, leaving some space between them.

Bake for 5 minutes at 340°F (170°C), then reduce the oven temperature to 140°F (60°C) and bake for an additional 40-45 minutes until crispy. Cool completely before serving.
