How to Make Marshmallow Icing with Marshmallows: The Ultimate Guide
Marshmallow icing, made directly from marshmallows, is a delightfully fluffy and sweet topping that’s surprisingly easy to create. This guide provides a step-by-step process to make delicious marshmallow icing by melting marshmallows with a few simple ingredients, offering a smoother and more flavorful alternative to powdered sugar-based frostings and perfect for cakes, cupcakes, and more.
What is Marshmallow Icing?
Marshmallow icing is a frosting made primarily from melted marshmallows. It’s characterized by its light, airy texture and intensely sweet marshmallow flavor. Unlike traditional buttercream, it uses marshmallows as its base, creating a unique and appealing alternative for decorating desserts. Its relatively simple preparation makes it an accessible option for both novice and experienced bakers.
The Allure of Marshmallow Icing: Benefits and Applications
Why choose marshmallow icing over other types? Here are some key advantages:
- Unique Flavor: The distinct marshmallow taste is a crowd-pleaser, especially for those who love sweet treats.
- Ease of Preparation: It requires fewer ingredients and steps than many other frostings.
- Smooth Texture: When made correctly, it results in a smooth and even texture, ideal for decorating.
- Versatility: While primarily used on cakes and cupcakes, it can also be used to top cookies, brownies, and even pies.
- Kid-Friendly: The familiar marshmallow flavor makes it a hit with children.
Assembling Your Ingredients: A Checklist
Before you begin, gather these essential ingredients:
- Marshmallows: The foundation of the icing; use fresh, standard-size marshmallows.
- Butter: Unsalted butter, softened, adds richness and helps create a smooth texture.
- Milk or Cream: Adds moisture and helps the marshmallows melt evenly. Cream will result in a richer flavor.
- Vanilla Extract: Enhances the marshmallow flavor and adds depth.
- Salt: Just a pinch helps balance the sweetness.
Step-by-Step Guide to Marshmallow Icing Perfection
Follow these steps for perfect marshmallow icing:
- Melt the Marshmallows: In a double boiler or a heatproof bowl set over a simmering pot of water (avoiding direct contact), combine the marshmallows, butter, and milk/cream.
- Stir Constantly: Stir the mixture continuously until the marshmallows are completely melted and smooth. This prevents burning and ensures a consistent texture.
- Remove from Heat: Once melted and smooth, remove the bowl from the heat.
- Add Vanilla and Salt: Stir in the vanilla extract and a pinch of salt.
- Cool Slightly: Allow the icing to cool slightly before using. This will help it thicken and become more manageable.
- Frost Your Dessert: Use a spatula or piping bag to frost your cake, cupcakes, or other desserts.
Troubleshooting: Common Mistakes and How to Avoid Them
Making marshmallow icing is simple, but some pitfalls can affect the outcome. Here’s how to avoid them:
- Burning the Marshmallows: Use a double boiler or low heat to prevent burning.
- Lumpy Icing: Stir constantly and ensure the marshmallows are fully melted.
- Icing That’s Too Thin: Allow the icing to cool slightly before using; this will thicken it. If it’s still too thin, add a tiny bit of powdered sugar, one tablespoon at a time, until the desired consistency is achieved.
- Icing That’s Too Thick: Add a tiny bit more milk/cream, one teaspoon at a time, until you reach the desired consistency.
Storage and Shelf Life
Marshmallow icing is best used fresh. However, leftover icing can be stored in an airtight container in the refrigerator for up to three days. Before using, allow it to come to room temperature and rewhip it to restore its fluffy texture. Note: Refrigerated icing may lose some of its original smoothness.
Recipe Variations: Adding Your Personal Touch
Consider these variations to customize your marshmallow icing:
- Chocolate Marshmallow Icing: Add melted chocolate or cocoa powder to the melted marshmallow mixture.
- Peanut Butter Marshmallow Icing: Stir in peanut butter for a nutty flavor.
- Coffee Marshmallow Icing: Add a teaspoon of instant coffee powder to the mixture.
- Colored Marshmallow Icing: Add food coloring to achieve your desired hue. Gel food coloring is preferred to avoid changing the consistency of the icing.

Frequently Asked Questions
Can I use mini marshmallows instead of regular marshmallows?
Yes, you can! Mini marshmallows melt more quickly and evenly than larger ones, potentially leading to a smoother icing. However, ensure you use the same weight of marshmallows as indicated in the recipe, not just the same volume.
What type of milk or cream is best for marshmallow icing?
Whole milk or heavy cream will both work well. Using heavy cream will result in a richer and creamier icing. If you want a lighter version, opt for whole milk. Avoid using skim milk, as it may not provide enough richness.
How can I prevent my marshmallow icing from being too sticky?
Ensuring the correct ratio of ingredients is crucial. Adding too much liquid can make the icing sticky. Also, allowing the icing to cool sufficiently before applying will help it set properly and reduce stickiness.
My marshmallow icing is grainy. What did I do wrong?
Grainy icing usually results from the sugar in the marshmallows not dissolving completely. This often happens if the heat is too high or if the mixture isn’t stirred constantly during melting. Make sure to use a low heat and stir until the marshmallows are completely melted and smooth.
Can I use marshmallow fluff instead of marshmallows?
While marshmallow fluff can be used, it will result in a different texture. Marshmallow fluff is already very smooth and light, so the resulting icing will be even lighter and less stable than icing made with regular marshmallows. You may need to adjust the liquid content to achieve the desired consistency.
How long does marshmallow icing last on a cake or cupcakes?
Marshmallow icing is best consumed within 24-48 hours of application. It can become sticky if exposed to humidity for extended periods. If storing frosted desserts, keep them in an airtight container in a cool, dry place.
Can I pipe marshmallow icing?
Yes, you can pipe marshmallow icing, but it may not hold its shape as well as buttercream. For best results, make sure the icing has cooled slightly and is thick enough to hold its form. Use larger piping tips for simpler designs.
How do I fix marshmallow icing that has separated?
If your marshmallow icing has separated, gently reheat it over a double boiler while stirring constantly. This can help to re-emulsify the mixture. Avoid overheating, as this can worsen the separation. A tiny whisk is helpful.
Can I add food coloring to marshmallow icing?
Yes, you can add food coloring. Gel food coloring is preferred because it adds color without altering the consistency of the icing as much as liquid food coloring. Add the color gradually until you achieve your desired shade.
Is there a vegan alternative to marshmallow icing?
Yes! Vegan marshmallows are available at many grocery stores. Use a recipe for vegan marshmallow icing, swapping the butter for a vegan butter substitute and using a plant-based milk or cream alternative.
Can I add extracts other than vanilla?
Absolutely! Experiment with other extracts like almond, peppermint, or lemon to create unique flavor profiles. Just remember that a little extract goes a long way, so add it gradually and taste as you go.
Why does my marshmallow icing look dull?
Marshmallow icing can sometimes appear dull. To enhance its shine, try adding a small amount of corn syrup to the melted marshmallow mixture. This will give it a glossier finish. Don’t add too much, or it will become sticky.
