A DELICIOUSLY EASY HANDHELD DESSERT

I'm going to give y'all the cheaters version to making whoopie pies (if you don't already make them this way yourself). Making baked goods totally from scratch is always wonderful if you have time, but honestly, making whoopie pies can be a bit tedious!. So I've tried to make this recipe easy to follow and to use tips to create perfect whoopie pies!

FREQUENTLY ASKED QUESTIONS:

What are Whoopie Pies?

They are basically individual handheld cake sandwiches with a cream filling. They are usually chocolate but you can find them in other flavors.

What is Whoopie Pie filling made of?

There are several ways to make the filling. Some use a shortening base filling which is the more traditional way. Others use a marshmallow based filling (like the one I am sharing here).

Why are whoopie pies called 'Whoopie'?

There are two competing theories. One is that they are named after a 1920's musical called "Whoopee!" where chocolate pies were thrown out to the audience during a song called "Makin' Whoopee". The other theory is that they were invented by Amish women who packed them into their husbands lunches and when the men opened their lunch pails, they would shout "Whoopie!"

What is the difference between a Moon Pie and a Whoopie Pie?

The only similarity is that they both are dessert sandwiches with cream filling. That is where the similarity ends. Moon Pies are more like cream-filled cookies. Whoopie Pies are more like cream-filled cakes.

How do I store leftovers?

Leftover whoopie pies should be individually wrapped in plastic wrap and stored in the refrigerator for up to 3 days. They can also be frozen. Individually wrap each whoopie pie in plastic wrap. Then wrap again in aluminum foil (to prevent freezer burn). They can be stored in the freezer for up to 3 months.

Once cookies are cooled, spread filling (about 2 tablespoons - you want a thick filling) on flat side of one cookie.

Cook's Tip: Marshmallow fluff can be a bit sticky to work with. Spray your measuring cups with nonstick spray to help it come out easier. Also, when you are spooning the filling onto the cakes, do the same thing. Just spray your spoon with nonstick spray and it will slide right out.
