Chocolate Chip Cookie Wafers Yield: Makes about 8–10 wafers 1 batch Cookie Dough Frosting 1. Preheat oven to 350°F. Take half of the frosting and make 1 tablespoon–sized balls on a parchment-lined baking sheet. Bake for 10–12 minutes, until they start to brown. They will spread out and become very flat and wafer like. 2. Remove from oven and cool completely. These are very thin wafer cookies, so be gentle when handling them. Spread remaining Cookie Dough Frosting on top once cool.
