How do I make jumbo cookies from a basic cookie recipe?
For jumbo cookies, prepare the dough as directed. Use a larger cookie scoop (3 to 4 tablespoons) to scoop the dough onto the cookie sheet, leaving about 3 inches between the mounds of dough (you might want to try a few to start with to see what size you like and to see how much they spread). Bake at a lower temperature (usually 350°F) for a few minutes more per batch (usually about 13 to 15 minutes). Again, you can check this by baking a few to start with.
