For Cookie Part: Beat shortening fluffy. Add sugar & beat. Add eggs & vanilla beat. Add molasses & beat. Sift all dry together & slowly adding a bit at a time beat dry into shortening batter. Chill dough
Roll dough into balls the size of walnuts. Dip in an egg wash of 1 egg beaten with 1 tablespoon of water. Dip every other dough ball into the crumb topping that I will give directions for later in the recipe.Place cookie balls on sheet with egg washed & dipped sides facing up.
Bake at 350 degrees for 10 to 12 minutes until puffed up & lightly brown ! Remove from sheets & let cool completely before filling
To make Shoofly Pie Goo : Mix the flour, brown sugar, shortening & salt together cutting it in for a crumb mixture , use a fork or pastry cutter. Remove 3/4 Cup & set this aside for your crumb topping to dip the cookie dough balls. Now take remaining crumbs mix & put into a deep saucepan, add the one egg beaten, the molasses & vanilla. Dissolve the baking soda in the hot water. Stir into the mixture in the saucepan. Whisk & cook over medium heat whisking the entire time. This will look like foamy coffee, keep stirring, MAGIC HAPPENS & SUDDENLY you will have a nice thick bubbly molasses goo ! Stir until all is thick & no longer watery. Remove from heat & chill. This will be the gooey bottom in the center of your whoopie pies.
White Fluffy Filling : Cream egg whites, vanilla, flour,salt, milk & 2 cups of the powdered sugar. Beat well. Add 2 cups more of the powdered sugar & the shortening & beat until fluffy. If you want this a little stiffer add more powdered sugar. If it gets to stiff just add a little more milk. This never fails & everyone likes their filling a different texture. In Whoopie Pies there is NO WRONG ! Play with it until you get it the way you like! Chill
Now take a cookie half that does not have crumbs, this is the bottom half of your whoopie pie. Smear about 1 & 1/2 to 2 teaspoons of the goo on the flat side of the cookie. Now take the cookie half that has crumbs ( this will be the top half of your whoopie pies.) Smear the flat side with a dollop of the Fluffy white filling. Place the Whoopie Pie halves together. You now have one big fat DELICIOUS Shoofly Whoopie Pie! Continue until all are filled. Store in an airtight container with wax paper between the layers. Refrigerate or freeze. Thaw before serving ! This makes about 44 Whoopie Pies! ENJOY this is my very own recipe . Check it out on my Recipe Blog at : recipesforjudysfoodies.blogspot.com
