Whoopie, let's celebrate a birthday. Betty Crocker SuperMoist party rainbow chip cake mix and plenty of sprinkles make this classic dessert into a party-worthy dish.
These whoopie pies can be made in advance and refrigerated. Be sure to remove them from the refrigerator about 15 minutes before serving.
To save time, substitute a container of Betty Crocker® Rich & Creamy cream cheese frosting or Betty Crocker® Whipped fluffy white frosting for the filling. If you do this, the whoopie pies don’t need to be stored in the refrigerator.
