For a richer flavor, use dark cocoa powder. Ensure the butter is properly softened for both the cake and filling to achieve the best texture. Don't overbake the cookies; they should be soft and slightly underdone. For easier handling, chill the filling for about 30 minutes before assembling the whoopie pies. Whoopie pies can be stored in the refrigerator for up to 3 days.

Feb 12, 2025The filling was a bit too sweet for my taste, so I reduced the confectioners' sugar by 1/4 cup and it was perfect.
