Whoopie Pies for Pi Day!

Whoopie Pies are a classic childhood treat.

Happy Pi Day! The week 5 recipe in the 52 Week New Recipe Challenge is whoopie pies. In celebration of Pi Day I made whoopie pies to send into my son’s math class. I’d never made them before so I went looking on-line and found this recipe. Many I found had a marshmallow filling and I wanted a buttercream filling. I’m not a fan of marshmallow filling and I wanted something not so sweet.

I found the recipe in an unlikely place. A site I never thought to look. The Reynolds Kitchens website. These whoopie pies were a hit with the kids. A keeper for sure.

  • In a medium bowl, sift together flour and cocoa powder. Beat in as much of the flour mixture then stir in remaining with wooden spoon if it gets difficult. (I was able to beat in all of the flour with the mixer.)

Beat in cooled milk mixture, one large spoonful at a time, into the mixture. Beating on high for one minute or until filling is smooth and fluffy.
