Giant Whoopie Pie Cake

In the past when I’ve used my grandmother’s whoopie pie recipe to make a giant whoopie pie cake, the filling was too soft and the cake top sort of slid off to the side shortly after assembly.  This time I tried a different frosting recipe, and it worked much better!

This filling recipe is the same filling used in Nellie Moody Jones’s Molasses Whoopie Pies.  I made a double batch to generously fill the giant whoopie pie cake shown above, though a single batch would probably be enough!

Whoopie Pie Filling

1/2 c. vegetable shortening

4 tbsp. Marshmallow Fluff

1 c. confectioners’ sugar

milk, as needed to achieve spreadable consistency.

Combine all ingredients and beat thoroughly using just enough milk to make the frosting spreadable.

    Have you found any vegetable shortening that is healthful?
    What I have seen is not.

    It’s so great to see someone who knows what a REAL whoopie pie is! I grew up on these and miss them so much now that I live in Florida. And seeing “Memere” on the cake makes me a little homesick – i miss my Memere and her whoopies! thanks for this sweet reminder of the good old days… i’ll have to make this soon. 🙂
