Best Substitutes for Marshmallows
Marshmallows bring three key things to recipes: sweetness, binding power from gelatin, and that distinctive chewy-soft texture. Regular marshmallows are about 80% sugar, 2% gelatin, and the rest is water and corn syrup. When melted, they create a sticky syrup that holds ingredients together in treats like Rice Krispie bars. The gelatin gives them stretch and chew. In baking, they puff up at 350F and caramelize at 425F. The challenge with substitutes is matching both the binding strength and the texture without making things too sweet or too dense.
Best Overall Substitute
Marshmallow fluff at a 1:1 ratio by volume. It has the same base ingredients as regular marshmallows but in spreadable form, so it melts smoothly without the extra step of breaking down solid pieces. Works perfectly in no-bake treats and gives identical binding power.
All Substitutes
Marshmallow fluff
1:1 by volumeFluff is essentially pre-melted marshmallows with corn syrup added for smoothness. It contains the same gelatin and sugar ratios as regular marshmallows but spreads at room temperature. When heated, it behaves exactly like melted marshmallows. The binding power is identical because the gelatin content matches. No texture difference in finished treats.
Vegan marshmallows
1:1 by count or volumeThese use agar or carrageenan instead of animal gelatin for structure. The binding power is about 90% as strong as regular marshmallows, so treats might be slightly less chewy. They melt at the same temperature (around 160F) but can be stickier when hot. Sugar content matches regular marshmallows at roughly 80%. Texture in finished recipes is nearly identical.
Corn syrup and powdered sugar paste
3 tablespoons corn syrup + 1/4 cup powdered sugar per 1 cup marshmallowsMix corn syrup and powdered sugar into a thick paste that mimics marshmallow's binding properties. The corn syrup provides stickiness while powdered sugar adds bulk and sweetness. This mixture melts smoothly and hardens when cooled, just like melted marshmallows. Binding strength is about 75% of regular marshmallows. Add 1 teaspoon vanilla for flavor depth.
Coconut flakes (toasted)
1/2 cup coconut flakes per 1 cup marshmallowsToasted coconut provides sweetness and chewy texture but zero binding power. Toast flakes in a 325F oven for 8-10 minutes until golden. The natural oils create slight stickiness when warm. This works only in recipes where you want texture and sweetness but don't need the ingredients to stick together firmly. Adds coconut flavor that wasn't there before.
Honey and gelatin mixture
1/4 cup honey + 1 packet unflavored gelatin per 1 cup marshmallowsSprinkle gelatin over 2 tablespoons cold water, let bloom for 5 minutes, then heat honey to 180F and whisk in bloomed gelatin until dissolved. This creates a marshmallow-like syrup with identical binding power. The honey adds deeper flavor than corn syrup. Binding strength matches regular marshmallows exactly because gelatin content is the same. Sets firm when cooled.
White chocolate chips
3/4 cup white chocolate chips per 1 cup marshmallowsWhite chocolate melts at 115F and hardens when cooled, providing decent binding power. The cocoa butter content (about 30%) gives richness that marshmallows lack. Sweetness level is similar but flavor is distinctly vanilla-chocolate instead of neutral. Binding power is about 60% of marshmallows, so add 2 tablespoons corn syrup to improve stickiness. Works best when melted first.
Sweetened condensed milk
1/3 cup condensed milk per 1 cup marshmallowsCondensed milk is 45% sugar and provides sticky binding when heated to 200F for 3-4 minutes. The milk proteins help bind ingredients together, though not as strongly as gelatin. Creates creamy texture rather than chewy. Binding power is about 50% of marshmallows, so combine with 1 tablespoon corn syrup for better hold. Adds dairy flavor.
Agave nectar and agar powder
1/4 cup agave + 1 teaspoon agar powder per 1 cup marshmallowsWhisk agar powder into 3 tablespoons cold water, bring to a boil for 2 minutes, then stir in agave nectar. Agar sets at room temperature and provides plant-based binding similar to gelatin. Agave adds sweetness with lower glycemic impact than corn syrup. Binding strength reaches about 80% of regular marshmallows. Sets firmer than gelatin when cooled.
Fruit leather pieces
1/2 cup chopped fruit leather per 1 cup marshmallowsCut fruit leather into small pieces to mimic marshmallow chunks. Provides chewy texture and natural fruit sweetness but zero binding power. Works only as a textural substitute in recipes that don't rely on marshmallow's binding properties. The pectin content gives slight stickiness when warmed. Choose neutral flavors like apple or pear to avoid overpowering other ingredients.
How to Adjust Your Recipe
When substituting in binding recipes like Rice Krispie treats, heat your substitute to 170F before mixing with cereal to ensure proper coating. If using a substitute with less binding power (like white chocolate or condensed milk), add 1-2 tablespoons corn syrup or honey to improve hold. For s'mores, only marshmallow fluff or vegan marshmallows will give that authentic gooey stretch when heated. In baking applications, reduce other liquids by 2 tablespoons when using liquid substitutes like condensed milk or honey mixtures. Most substitutes work better when chopped into small pieces rather than used whole.
When Not to Substitute
Campfire roasting requires actual marshmallows because only they have the right balance of sugar and gelatin to caramelize properly on a stick without melting off. Classic s'mores need the specific texture that comes from heating solid marshmallows until the outside sets while the inside stays gooey. Professional candy making often requires the exact binding properties of gelatin-based marshmallows. Hot chocolate toppers need something that floats and slowly dissolves, which most substitutes can't replicate.
Frequently Asked Questions
Can I make my own marshmallows as a substitute?
Yes, but it takes 3 hours total time. Bloom 3 packets unflavored gelatin in 1/2 cup cold water, then heat 1/2 cup water with 1.5 cups sugar to 240F. Pour hot syrup into bloomed gelatin while beating with a mixer for 12-15 minutes until thick and cool. Pour into an 8x8 pan dusted with powdered sugar and let set for 2 hours before cutting.
How much marshmallow fluff equals one regular marshmallow?
One large marshmallow equals about 1 tablespoon of fluff. A standard 10-ounce jar of fluff replaces about 40 large marshmallows or 4 cups of mini marshmallows. For recipes calling for a specific number of marshmallows, measure the fluff by volume rather than trying to count equivalents.
Do vegan marshmallows melt the same way as regular ones?
Vegan marshmallows melt at 160F, identical to regular marshmallows, but they can be stickier when hot. They provide about 90% of the binding power. In Rice Krispie treats, use the same melting technique but press the mixture into the pan while still warm since vegan versions set up faster as they cool.
What happens if I use too much substitute in a recipe?
Too much sweet substitute (like condensed milk or honey mixture) makes treats overly sweet and can prevent proper setting. Excess binding agents create gummy, dense textures. Start with 75% of the recommended substitute amount, test the consistency, then add more if needed. Most substitutes are more concentrated than marshmallows.
Can I use marshmallow substitutes for roasting over a fire?
Only vegan marshmallows work for campfire roasting. Fluff and liquid substitutes will melt off the stick. Solid substitutes like white chocolate chips burn at high heat rather than caramelizing. For outdoor s'mores, stick with actual marshmallows (regular or vegan) or use marshmallow fluff in indoor broiler s'mores instead.
