Line a baking tray with parchment paper or use a silicone mat.
Mix shredded cheeses and chili powder in a medium bowl.
Then spoon about a tablespoon onto the silicone mat in a round shape. The chips should be about 2 inches wide and not too thick, so they can crisp up better. Leave at least an inch in between chips as they will melt into a larger shape.
Bake for 4-5 minutes until the edges are a golden brown. The center will be bubbly, but will crisp up when cooled. Be careful with the cheese chips in the oven as they do burn easily.
