Preheat oven to 350 and line baking sheet with a silicone baking mat. Use parchment paper instead if you don't have a baking mat.
In a small bowl, whisk together the coconut flour, onion powder, and xanthan gum. Set aside.
In a large microwaveable bowl, melt the cheese on high until it's completely melted and can be easily stirred.
Stir in the coconut flour mixture into the melted cheese with a rubber spatula until combined and a soft dough forms
Place the dough on the silicone mat and divide it into 3-4 equal portions. Roll the portions into logs about 6-8 inches long. Use scissors (makes it so easy!) to cut each log into 1" pieces.
Scatter the pieces over the silicone baking mat and bake 8-10 minutes until golden and firm.
Serve in Keto Gnocchi Soup or store in the fridge for up to 2 weeks.
