Description

These Confetti Whoopie Pies are a playful, handheld twist on sprinkle-flecked birthday cake. Start with a box of our Confetti Cake & Cupcake Mix and transform it into soft cookies sandwiched with fluffy marshmallow cream filling. The classic vanilla aroma and colorful sprinkles make them irresistibly festive for kids' birthday parties and grown-up celebrations alike. Bonus: They're easy to transport, can be made ahead, and stay fresh for up to three days.
