Ever had a go at making your own whoppie pies? The traditional American baked good looks impressive but they’re much easier to make than you’d think. They’re made of two layers of chocolate cake, sandwiched together with a tasty filling. Rich Chocolate always tastes great next to refreshing mint and these chocolate whoopie pies taste fantastic with the creamy buttercream with a hint of peppermint, giving them an extra cool kick.
