Fillings and Frostings

Frostings and fillings can make or break a dessert—and when it comes to treats like Whoopie pies, they’re the heart of it. Whether you’re sandwiching soft chocolate cakes or spreading something sweet between layers of a rustic sheet cake, a good filling ties it all together. This recipe uses simple, everyday ingredients—no shortening, no artificial flavorings—just real butter, cream, sugar, and a touch of vanilla. It’s smooth, sweet, and sturdy enough to hold its shape, but soft enough to melt into every bite. Perfect for Whoopie pies, cookies, cakes, or anything else that needs a little extra love in the middle.
