Did you know you can bake cookies in a muffin tin?
Theoretically. If, for example, your five year old scrubbed your (only, nonstick) cookie sheet with steel wool and you didn't want to buy a new one.
You could still make lovely, thick cookies. There wouldn't be any complaints. They even make perfect circles.
They boys and I made pumpkin cookies this way, over the weekend. We replaced/reduced the 1-1/2 cups of sugar with 1/2 cup of honey (and used olive oil instead of butter since we didn't have any) and they were soft, with just enough sweetness. Actually, by the time we drizzled them with cinnamon glaze, you didn't miss the sugar at all.
