Why You’ll Love This Strawberry Marshmallow Frosting
- Sweet strawberry flavor: Strawberry preserves or freeze-dried strawberries add a fruity taste.
- Fluffy texture: Marshmallow cream creates a soft, airy consistency.
- Beautiful pink color: A naturally pretty frosting for special occasions.
- Easy to prepare: Simple ingredients come together without complicated techniques.
- Versatile: Delicious on cupcakes, layer cakes, cookies, and brownies.
Ingredients
- 1 jar (7 ounces) marshmallow creme: Gives the frosting its signature fluffy texture and marshmallow sweetness.
- ½ cup unsalted butter, softened: Adds richness and helps the frosting hold its shape.
- 1 cup powdered sugar: Sweetens and thickens the mixture.
- ¼ cup strawberry preserves: Provides strawberry flavor and a soft pink tint.
For a stronger strawberry flavor and brighter natural color, you can substitute finely ground freeze-dried strawberries for some or all of the preserves. Avoid adding too much liquid, which can make the frosting too soft.
How to Make Strawberry Marshmallow Frosting
Step 1: Beat the Butter
Place the softened butter in a large mixing bowl. Beat with an electric mixer for 2–3 minutes, until pale and creamy.
Scrape down the sides of the bowl to ensure the butter is evenly whipped.
Step 2: Add the Powdered Sugar
Add the powdered sugar gradually, mixing on low speed at first to prevent it from scattering.
Once incorporated, increase the mixer speed and beat until the mixture is smooth and fluffy.
Step 3: Mix in the Marshmallow Creme
Add the marshmallow creme and beat on medium speed until fully combined.
The mixture should look glossy, light, and creamy. Scrape the bowl as needed to incorporate all the ingredients evenly.
Step 4: Add the Strawberry Preserves
Add the strawberry preserves and beat briefly until the frosting turns a soft pink color.
If the preserves contain large pieces of fruit, stir them well first or strain them for a smoother frosting. Add the preserves gradually so the frosting does not become too loose.
Step 5: Adjust the Consistency
If the frosting is too soft, add a little more powdered sugar, one tablespoon at a time. If it is too thick, mix in a small amount of strawberry preserves, taking care not to add too much liquid.
For easier piping, refrigerate the frosting for 15–20 minutes before using.
Step 6: Frost Your Desserts
Spread the frosting over completely cooled cakes or cupcakes with a spatula, or transfer it to a piping bag for decorative swirls.
For the best results, avoid frosting warm baked goods, as heat can soften the butter and marshmallow creme.
Tips for the Best Strawberry Marshmallow Frosting
Use softened butter, not melted butter. Softened butter whips properly and helps the frosting maintain its structure.
Add strawberry flavor gradually. Too much preserve can make the frosting runny. Start with the recommended amount and adjust carefully.
Use smooth preserves for piping. Large fruit pieces can clog piping tips, so strain the preserves if you want neat decorations.
Let the cake cool completely. Warm cake can cause the frosting to melt or slide.
Chill if needed. A short time in the refrigerator helps the frosting firm up, especially in a warm kitchen.
Easy Variations
Fresh Strawberry Marshmallow Frosting
For a stronger fresh-strawberry flavor, use finely ground freeze-dried strawberries or a small amount of thick strawberry reduction. Fresh strawberries contain considerable moisture, so avoid adding them directly in large quantities.
Strawberry Chocolate Frosting
Spread the frosting over chocolate cupcakes or brownies for a delicious chocolate-and-strawberry combination.
Vanilla Strawberry Frosting
Add ½ teaspoon vanilla extract for a softer, bakery-style flavor.
Extra-Pink Frosting
Use a small amount of pink food coloring if you want a more vibrant shade without adding extra strawberry liquid.
Strawberry Cream Cheese Marshmallow Frosting
For a tangier variation, replace part of the butter with softened cream cheese. This will change the consistency and make refrigeration especially important.
What to Serve with Strawberry Marshmallow Frosting
This frosting pairs beautifully with:
- Vanilla cupcakes
- White or yellow cake
- Chocolate cake
- Brownies
- Sugar cookies
- Strawberry cupcakes
- Graham cracker sandwiches
- Mini dessert cakes
For a simple dessert, spread a thin layer between two graham crackers and chill briefly for an easy sweet sandwich.
How to Store Strawberry Marshmallow Frosting
Because this frosting contains butter and fruit preserves, store it in an airtight container in the refrigerator for up to 4 days.
Before using refrigerated frosting, let it soften slightly at room temperature and beat it briefly until smooth. If it becomes too soft, refrigerate it again for a short time before piping.
For food safety, do not leave frosted desserts at room temperature for more than 2 hours, especially in warm weather.
Freezing is possible, although the texture may change slightly after thawing. Store in a freezer-safe container for up to 1 month for best quality. Thaw overnight in the refrigerator, then beat briefly before using.
Frequently Asked Questions
Can I use fresh strawberries?
Fresh strawberries can add flavor, but their moisture may make the frosting too soft. For a more reliable result, use thick strawberry preserves or finely ground freeze-dried strawberries.
Is this frosting suitable for piping?
Yes, for simple swirls and borders. If you want firm, detailed decorations, chill the frosting before piping and adjust the consistency with small amounts of powdered sugar if necessary.
Can I make this frosting ahead of time?
Yes. Prepare it up to 4 days ahead and refrigerate it in an airtight container. Let it soften slightly and beat briefly before using.
Why is my strawberry frosting too runny?
The preserves may contain too much liquid, or the butter may have become too warm. Add powdered sugar a tablespoon at a time and chill the frosting until it firms up.
Can I use strawberry jam instead of preserves?
Yes. Smooth strawberry jam works well. If it contains large fruit pieces, strain it first for a smoother finish.
Is marshmallow creme the same as marshmallows?
No. Marshmallow creme is a soft, spreadable confection that blends easily into frosting. Regular marshmallows have a firmer structure and are not a direct substitute in this recipe.
