How to prevent cookies from burning?
How do you make cookies that don't burn?
Always cook at the lowest cooking time suggested. if a recipe says “Bake for 10 to 12 minutes”, bake for 10 minutes.

Line baking sheets with parchment paper. Not only will this help minimize the risk of burning, but you won't have to clean up the pans; just toss the paper, let the pans cool, then put them away.
