Why You’ll Love This Frosting
Strawberry Marshmallow Frosting stands out for several reasons:
- Light and fluffy texture – almost like whipped clouds
- Naturally flavored with real strawberries
- Less heavy than butter-based frostings
- Perfect for decorating or spreading
Ingredients You’ll Need
To make this frosting, gather the following:
- 1 cup fresh strawberries (hulled and chopped)
- 3/4 cup granulated sugar
- 2 large egg whites
- 1/4 teaspoon cream of tartar
- 1 teaspoon vanilla extract
- Pinch of salt
Step 1: Prepare the Strawberry Puree
Start by placing the chopped strawberries in a small saucepan over medium heat.
- Cook for about 5–7 minutes, stirring occasionally
- Mash the strawberries as they soften
- Continue cooking until the mixture thickens slightly
Once done, strain the mixture to remove seeds if you prefer a smoother frosting. Let the puree cool completely before using.
Step 2: Set Up a Double Boiler
Fill a saucepan with a few inches of water and bring it to a gentle simmer. Place a heatproof bowl on top, ensuring it doesn’t touch the water.
In the bowl, combine:
- Egg whites
- Sugar
- Cream of tartar
- Pinch of salt
Step 3: Heat and Whisk
Whisk the mixture constantly over the simmering water.
- Continue until the sugar fully dissolves
- The mixture should feel smooth (no graininess when rubbed between fingers)
- This usually takes about 3–5 minutes
This step ensures the frosting is safe and stable.
