Keto Whoopie Pies! This is such an easy recipe and such a fun one too! These low-carb whoopie pies are an American favorite that is perfect for birthday parties, special occasions, or just a random sweet treat.

You’d think they would be hard to make but it’s really simple — you’ll start by making the soft chocolate cookies then whipping up the quick buttercream to stuff them with. You could also add any flavorings you wish to the filling, salted caramel anyone?
