I got this recipe in 1984 from my friend Diane Bell. My note on the recipe reads “treat city.” That sums it up nicely. Originally, the recipe was for full round Whoopie Pies but I found the size overwhelming. These Half Moon Pies are just right for me but if you want to make just six full Whoopie Pies instead of the 12 Half Moon Pies, go for it!
For the cookie/cakes:
½ cup butter, softened
1 cup brown sugar
2 egg yolks
1 teaspoon vanilla extract
2 cups unbleached all purpose flour
½ cup cocoa
1 teaspoon baking soda
½ teaspoon salt
1 cup buttermilk
For the filling:
12 Tablespoons unsalted butter
1½ cups icing sugar
Pinch salt
1½ teaspoons vanilla
2½ cups marshmallow fluff
