Try to make the dough balls the same size.Once baked, you’ll want both the top and the bottom of each whoopie pie to match. A cookie scoop will help you portion the batter perfectly.
Let them cool.Adding cream cheese frosting to warm pumpkin cookies would be a disaster! Be sure that the cookies are completely cool before adding the filling.
To Store:Store your pumpkin whoopie pies in an airtight container in the refrigerator. If kept this way, they will stay fresh for 4-5 days. After that, they will start to dry out. Let the whoopie pies sit at room temperature for a bit before eating so that the frosting can soften.
To Freeze:They freeze quite well. It’s best to wrap each whoopie pie individually with plastic wrap, then place the wrapped cookies in a zipper bag or freezer container. Store in the freezer for up to 6 months. Let frozen whoopie pies thaw on the counter for 30 minutes before enjoying.
