What You’ll Need

Here’s everything you need to make this soft and fluffy strawberry marshmallow frosting:

• Unsalted butter, softened – 1 cup (226 g)
• Marshmallow crème (marshmallow fluff) – 1 cup (240 g)
• Powdered sugar (confectioners’ sugar) – 2½ cups (300 g)
• Strawberry puree (fresh or frozen, blended smooth) – ¼ cup (60 ml)
• Vanilla extract – 1 teaspoon (5 ml)

How to Make Strawberry Marshmallow Frosting

Follow these simple steps to make perfectly fluffy strawberry marshmallow frosting:

1. Beat the butter
   Add the softened butter to a large mixing bowl and beat it for 2–3 minutes until it looks pale, smooth, and creamy.
2. Add the marshmallow crème
   Spoon in the marshmallow crème and beat again until the mixture looks light, fluffy, and fully combined.
3. Mix in the powdered sugar
   Add the powdered sugar gradually, ½ cup at a time, beating on low speed first, then increasing to medium until smooth and lump-free.
4. Add strawberry flavor
   Pour in the strawberry puree, vanilla extract, and salt. Beat until the frosting turns soft pink and the strawberry flavor blends evenly.
5. Adjust texture and taste
   If the frosting feels too soft, add a little more powdered sugar. If you want a stronger strawberry flavor, mix in freeze-dried strawberry powder.
6. Finish and fluff
   Beat the frosting for one final minute until it looks airy, fluffy, and ready to spread or pipe.

💡 Tip: Chill the frosting for 10–15 minutes if you want it slightly firmer for piping.

TIPS & VARIATIONS

Here are my favorite tips and easy ways to customize this strawberry marshmallow frosting:

Helpful Tips

• Use room-temperature butter so the frosting turns smooth and fluffy without lumps.
• If your strawberry puree feels watery, simmer it for a few minutes and let it cool to concentrate the flavor.
• Beat the frosting well at the end to trap air and create that light, cloud-like texture.

Easy Variations

• Extra strawberry flavor: Add freeze-dried strawberry powder for a stronger taste without thinning the frosting.
• Chocolate-strawberry twist: Mix in 2 tablespoons (30 ml) of melted, cooled white chocolate for a dessert-style frosting.
• Dairy-free option: Use plant-based butter and vegan marshmallow crème for a dairy-free version.

Storage Tips

• Store leftover frosting in an airtight container in the refrigerator for up to 3 days.
• Let it sit at room temperature for 10–15 minutes, then re-whip before using.

SERVING IDEAS
