Why You’ll Love This Frosting (Besides the Obvious)

This isn’t your average buttercream frosting. It’s the marshmallow frosting that shows up fashionably late and still steals the spotlight:

• Pipes like a pro—perfect for cupcakes, cookie sandwiches, and layer cakes that need a little lift.
• Silky smooth texture thanks to whipped butter and marshmallow fluff. It’s like a hug for your taste buds.
• Make-ahead friendly and still fluffy hours later. It’s the frosting that doesn’t ghost you.
• Kid-approved and adult-adored. Sweet, soft, and gone in seconds.

Ingredients

• ½ cup unsalted butter, room temperature (soft, not sad)
• 7 oz Marshmallow Fluff (the real MVP)
• 1 cup powdered sugar
• 1 ¼ tsp pure vanilla extract

Directions

1. Cream the base: Beat butter and powdered sugar until it’s light, fluffy, and looks photo-ready.
2. Add the magic: Gently fold in marshmallow fluff and vanilla. No overmixing—this isn’t CrossFit.
3. Frost and serve: Pipe onto cupcakes, cakes, or cookies. Or eat it straight from the bowl—no judgment here.
