You can make larger whoopie pies if you prefer a more heartier or substantial dessert. When portioning out the batter onto your baking sheet, use a larger amount for each cookie portion. Instead of a smaller scoop, use a larger cookie scoop or spoon to create bigger rounds of batter. Since the larger-sized pies will take longer to bake, increase the baking time accordingly. Keep an eye on them and check for doneness by gently pressing the tops; they should spring back when they're ready. I love to play with different sizes!
