I want to make Boston cream whoopie pies and I'm wondering if anyone has done this and can share a recipe.
I assumed I could use any recipe and bake as whoopie pies, assembling with the custard filling and chocolate ganache topping. My concern is with the cake part of the recipe. Anyone have any guesses as to whether a standard sponge cake batter will bake up into the characteristic whoopie pie cake mounds when spooned onto a parchment-lined baking sheet? Would I be better off using a yellow cake recipe instead?
