The first whoopie pie was a tangy chocolate cake, with a dreamy vanilla, marshmallow filling. But that was in the 1920s. In 1935, Little Debbie came along with her iconic oatmeal cream pies. The coffee trend of the 2000s then brought us espresso pies. It's now 2017 and we're all about rainbows: rainbow bagels, rainbow spaghetti, and of course, rainbow whoopie pies. Here's how to make these whimsical rainbow pastries.

    In a large bowl, beat together 1/4 cup butter and sugar until light and fluffy.

    #SpoonTip: We ideally want the butter to be room temperature, but it's fine to soften the butter by heating it up in the microwave on high in 10 second increments.
