wire rack, allowing them to cool completely before sandwiching together.

5. While the sponges are cooking, you can make the filling. Using the electric

whisk or freestanding mixer with the paddle attachment, mix together the
butter and the icing sugar on a low speed until well blended. Add the
marshmallow fluff, and lightly mix it in, then increase the speed to high and
continue mixing until light and fluffy. Place in the fridge and leave for about
30 minutes to firm up slightly.

6. To assemble the whoopie pies, take one of the sponges and spread about 1
tablespoon of the filling over the flat side, adding a little more if needed. Then

stick another sponge, with the flat side facing down, on the filling to make a
sandwich. Repeat with the remaining sponges and filling.
