1. Playing Around
Whopper-Size Whoopie Pies. If you use a large cookie scoop (one with a capacity of 3 tablespoons) to portion out the dough, you can make 6 really big pies (12 cookies; 6 pies). These bake best when you use an insulated baking sheet or stack two sheets one on top of the other. Line the (top) sheet with parchment paper or a silicone baking mat and bake the cookies for 15 to 17 minutes.
The unfilled cookies can be kept covered at room temperature for up to 1 day. Once filled, they can be kept covered in the refrigerator for a day or two, but they’re really best the day they’re made.
