Whoopie Pies

For the cake, cream together sugar and shortening. Add lightly beaten egg yolks until well mixed. Mix in dry ingredients, alternating with milk/vanilla mixture. Pipe or spoon in circles on parchment paper and bake at 375 degrees for 8 minutes.

For the filling, in a saucepan on medium heat, melt marshmallows and corn syrup until a liquid mixture is achieved. Cream with shortening in a mixer on medium speed. Slowly add powdered sugar and salt, mix well. Finally add egg whites and beat on high speed 2 minutes. Add more powdered sugar if needed. Pipe between two whoopie pie cakes.
