Place the mozzarella and cream cheese into a microwave safe bowl. Heat the mixture for 30 seconds at a time until well blended and smooth.
Add the cheese dough to a mixing bowl with the almond flour, xanthan gum, garlic powder, baking powder, egg white and salt. Blend until a smooth dough has formed.
Chill the dough for 30 minutes.
Preheat the oven to 350°F.
Roll the dough out to about ¼ of an inch thick between two pieces of parchment paper.
Use a pizza cutter to cut out strips from the dough.
Wrap the strips of dough around the brie cheese to form the mummy design.
Place on a parchment-lined baking sheet and bake for 20-25 minutes until the brie has melted.
Place two pieces of mini pepperoni on the front of the mummy face to form its eyes.
Cut two slices of black olive, and place them over the pepperoni on the front of the brie mummy.
Notes
Fathead dough can become sticky and challenging to work with as it warms up. Since you're wrapping it around the brie like mummy bandages, you want it to remain pliable but not overly sticky. To achieve this, keep the fathead dough cold until you're ready to use it.Work efficiently to cover it completely once you start wrapping the brie with the fathead dough. The quicker you can wrap it up, the better the dough will stay cold and manageable.To achieve a beautiful, golden-brown crust on your mummy baked brie, apply an egg wash before baking. Beat an egg and brush it over the fathead dough. This will give your mummy bandages a glossy finish and a rich color when they come out of the oven.
