Cut the cheese slices into small, equal squares and place them on the baking pan in a single layer, with 2 inches of space between each square to allow them to expand while baking.
Line the baking pan with parchment paper to prevent the cheese crackers from sticking to the pan.
Bake the cheese crackers in a preheated oven at 350°F for 15 minutes. Do not increase the temperature or over bake the cheese crackers, or they will become burnt and taste bitter.
