Tips & Substitutions

To achieve the best texture, ensure your egg whites are at room temperature before beating them to stiff peaks. If you're short on marshmallows, consider using a marshmallow fluff as a substitute, adjusting the sugar and water accordingly. For added flavor, a splash of vanilla extract can elevate this frosting. This white marshmallow frosting is also great for topping Tunnel Cake or other desserts.

Store any leftover frosting in an airtight container in the refrigerator for up to 3 days. When ready to use, let it come to room temperature and gently rewhip it to restore its texture. Avoid freezing the frosting as it may change consistency upon thawing.

Frequently Asked Questions

Can I use powdered sugar instead of granulated sugar?

Using powdered sugar instead of granulated sugar is not recommended for this recipe, as the texture and stability of the frosting may be affected. Granulated sugar helps create the syrup needed for the right consistency, while powdered sugar would create a different texture.

What can I substitute for egg whites?

If you're looking for an egg-free option, you can use aquafaba, the liquid from canned chickpeas, as a substitute for egg whites. Use about 3 tablespoons of aquafaba to replace each egg white. Just whip it until stiff peaks form, similar to egg whites.

How can I make this frosting more stable for warm weather?

To make your frosting more stable in warm weather, consider adding a tablespoon of cornstarch to the sugar mixture before boiling. This can help absorb moisture and maintain the frosting's structure. Additionally, serving your frosted treats chilled can help keep them firm.
