Whoopie pies are a popular baked item in many Amish communities. You can make a simple version using boxed cake mix, spoon onto a baking sheet to make tops and bottoms and when cool, use vanilla or chocolate frosting for the center, like a sandwich. Add food coloring to white cake mix if you want a pink or green whoppie pie for Easter or spring. Marshmallow cream can also be used as a filling.
