Quick Answer
Yes, you can use marshmallow fluff instead of mini marshmallows in most recipes. Marshmallow fluff and mini marshmallows have a very similar texture and sweetness. The main difference is that marshmallow fluff is a syrupy puree while mini marshmallows maintain their shape.
Marshmallow fluff can be swapped in at an equal volume to mini marshmallows in recipes where marshmallows are stirred in, like in dessert dips, hot chocolate, and rice krispie treats. For recipes where marshmallows are supposed to hold their shape and toasted, like in s’mores, it’s best to use mini marshmallows. Marshmallow fluff will melt too quickly when exposed to high heat.
Marshmallow Fluff Overview
Marshmallow fluff, sometimes called marshmallow creme, is a sweetened marshmallow puree. It’s made by whipping gelatin, sugar, water, and vanilla extract into a smooth, spreadable consistency. The first marshmallow fluff products debuted around 1917 and it became especially popular in New England.
Marshmallow fluff has a soft, fluffy texture thanks to all the tiny air bubbles beaten into it. It’s sticky, smooth, and rich with a distinct vanilla flavor. You can eat marshmallow fluff straight from the jar or use it in recipes as a substitute for marshmallows. It comes in 7-8 oz jars and larger family-size containers.
Some of the most popular name brand marshmallow fluffs include:
- Kraft Jet-Puffed Marshmallow Fluff
- Durkee Marshmallow Fluff
- Polar Fluff
- Snowflake Marshmallow Fluff
You can also find generic and store brand versions. Marshmallow fluff is widely available in the baking aisle of grocery stores, especially in the Northeastern United States.
Marshmallow Fluff Nutrition
Marshmallow fluff is high in sugar and doesn’t offer much in the way of nutrition. A 2 tablespoon serving contains:
- Calories: 100
- Fat: 0g
- Carbs: 25g
- Protein: 0g
As you can see, most of the calories come from carbohydrates in the form of sugar. The calorie count quickly adds up when eating marshmallow fluff by the spoonful or in baked goods. It’s best enjoyed occasionally as a sweet treat.
Comparing Marshmallow Fluff to Mini Marshmallows
Marshmallow fluff and mini marshmallows are made with the same basic ingredients – sugar, gelatin, water, and vanilla. Here’s how they compare:
Texture
Marshmallow fluff has an ultra smooth, pudding-like consistency that easily spreads and incorporates into batters. Mini marshmallows have more structure and “chew”. They hold their shape when mixed into recipes.
Sweetness
Marshmallow fluff and mini marshmallows have an equally sweet flavor. Sugar is the main ingredient in both.
Uses
Marshmallow fluff and mini marshmallows can be used interchangeably in recipes where maintaining structure isn’t important. For example, Rice Krispie treats, rocky road fudge, and dessert dips.
Mini marshmallows are better for recipes where the marshmallows are toasted orneed to hold shape, like s’mores, candied yams, or crispy treats. The mini marshmallows won’t melt into a puddle of goo.
Convenience
Marshmallow fluff requires no prep – just open the jar and you’re ready to use it. Mini marshmallows may need to be chopped or cut smaller depending on the recipe.
| Characteristic | Marshmallow Fluff | Mini Marshmallows |
|---|---|---|
| Texture | Smooth, pudding-like | Structured, chewy |
| Sweetness | Very sweet | Very sweet |
| Uses | Stirred into batters, frostings, dips | Toasting, holding shape, mix-ins |
| Convenience | Ready to use from the jar | May need chopping |
Substituting Marshmallow Fluff in Recipes
When swapping marshmallow fluff for mini marshmallows, the most direct substitution is:
1 cup mini marshmallows = 1 cup marshmallow fluff
Since fluff is pureed, it doesn’t take up as much volume in a measuring cup as loose mini marshmallows. So when substituting, it’s fine to firmly pack the fluff into the measuring cup to achieve the right amount.
Here are some tips for getting the best results when using marshmallow fluff in place of mini marshmallows:
- For recipes where marshmallows are melted or stirred in, fluff and mini marshmallows can be used interchangeably. Examples include rocky road fudge, sweet potato casserole, and hot chocolate.
- In baked goods like rice krispie treats and dessert bars, marshmallow fluff may affect texture slightly but will still work well. You may need to adjust cook times.
- For s’mores, candied yams, crispy treats, or other recipes where marshmallows are toasted or browned, stick with mini marshmallows. Fluff will melt too quickly under high heat.
- Since marshmallow fluff is pureed, it incorporates more easily into batters and frostings without over-mixing.
- If a recipe calls for cutting mini marshmallows in half or into pieces, you can skip this step when using fluff.
- Reduce other liquids slightly in the recipe to account for the syrupy texture of marshmallow fluff.
- Add a pinch of salt to balance out the sweetness, if needed.
Always taste the dish as you go to ensure the flavor and texture are right with the substitution. Keep in mind marshmallow fluff contains salt and vanilla flavoring so you may need to adjust seasoning.

Storing Leftover Marshmallow Fluff
Marshmallow fluff lasts for 1 to 3 months unopened at room temperature. Once opened, it will keep for a month or longer refrigerated. To help it keep its fluffiness:
- Transfer unused marshmallow fluff to an airtight container before refrigerating.
- Press plastic wrap directly on the surface before sealing to prevent dry skin from forming.
- If fluff hardens in the fridge, let it sit at room temp to soften before using.
- Fluff may thin out slightly upon thawing but regains its texture once whipped.
- Re-fluff in a stand mixer if needed.
- Stir in a tablespoon of powdered sugar to thicken fluff back up.
Properly stored, marshmallow fluff maintains optimal flavor and texture for weeks in the refrigerator. It can also be frozen for longer term storage. Thaw overnight in the fridge before using.
Conclusion
Marshmallow fluff can be used in place of mini marshmallows in most recipes, especially where marshmallows are stirred into a batter or sauce. Its creamy, whipped texture allows it to seamlessly blend into all kinds of treats from fudge to cupcakes. Just don’t use it for recipes where the marshmallows need to toast.
When substituting marshmallow fluff for mini marshmallows, use an equal amount. You may need to adjust cooking times slightly in baked goods. Overall, marshmallow fluff makes a convenient, ready-to-use alternative in sweet and savory recipes calling for mini marshmallows.
