Whoopie Pies...

Here's a Favorite...
Maybe I should keep it "Top Secret", but the world deserves to know...Cake part:
1 cup shortening
2 cups sugar
2 eggs YOLKS (don't toss the whites!)
1 cup soured milk (1 cup milk + 1 tablespoon vinegar or lemon juice)
1 cup HOT water + 2 teaspoons baking soda (soda dissolved in water)
1 teaspoon vanilla
4 cups flour
1 cup cocoa
1/2 teaspoon salt
Cream the shortening and sugar. Add the yolks one at a time, and mix until well incorporated. Add the milk mixture, cocoa, and flour. Add the soda/water mixture while mixing. Drop by teaspoonfuls (I like to use my Pampered Chef cookie dough scoop) onto a greased cookie sheet and bake at 400 for 8-10 minutes. Let cool.

Creme:
2 egg WHITES (see, they come into play...)
2 teaspoons vanilla
1 1/2 cups shortening
4 tablespoons flour
4 tablespoons milk
dash of salt
Powdered Sugar

Cream all together and add the powdered sugar until the creme reaches a thick, but spreadable, consistency. (I usually use about a pound, sometimes more...)
Match up your cooled cookie halves, and spread creme on one side, place its mate on the other (kinda like an Oreo... but better!). Finish for all! I love to eat more than one at a time well chilled with milk and even stash some in the freezer for those unforgettable PMS days... they make a great breakfast treat too :).
Enjoy!
