My sister and I made this the other day and it is SO delicious!  While it does take a little time, it’s very simple to make and tastes so much better than the store bought marshmallow fluff!

This recipe uses vanilla for flavoring, but I can’t wait to make it again and play with the flavorings by adding different extracts… next on my list to try is almond!

While there is corn syrup in this recipe… it is NOT the same product as that High Fructose Corn Syrup which most of us are trying to avoid.  I hope you enjoy this homemade marshmallow fluff recipe!

Did you make this recipe?


  • 3 large egg whites
  • 1/2 teaspoon cream of tartar
  • 2 tablespoons granulated sugar
  • 3/4 cup golden corn syrup
  • 2/3 cup granulated sugar
  • 1/2 teaspoon vanilla extract


  1. With a whisk attachment, beat the egg whites and cream of tartar until foamy.
  2. Add 2 tablespoons of sugar and beat until soft peaks form, set aside.
  3. Meanwhile, in a saucepan, add 1/3 cup water, corn syrup, and 2/3 cup sugar.
  4. Cook over medium heat while stirring until the mixture reaches firm ball stage (instructions below) or 248 degrees on a candy thermometer. This step will take about 15 minutes.
  5. Once the corn syrup mixture has reached firm ball stage, turn the mixer onto medium and in a slow steady stream, pour the corn syrup mixture into the beaten egg whites.
  6. Once all of the corn syrup mixture has been added, beat on high for 5 minutes.
  7. Add vanilla extract and beat on high 1 minute
  8. Store in a tightly sealed container

To test for firm ball stage:

  1. Fill a glass with cold water and drop a small spoonful of the mixture into the cold water. Remove the mixture from the cold water and it should hold its shape, but quickly flatten.

  1. I think I have a recipe very similar to this where you use honey…I think it was from a cookbook called “The Wheat Book.”

  2. Thank you so much for sharing!! xoxo I’ve been looking for this!! Thank you again

  3. Do you let the syrup mixture cool? Seems like pouring 248° syrup onto egg whites will just “cook” them.

    • I did not let the syrup cool. I just made sure I poured it very slowly in a thin stream.

      • Just be sure your mixer is on when you add the syrup. I make an Italian Meringue Buttercream that uses the same method.

    • Well, the syrup does cook the egg whites, but you pour it very slowly so it doesn’t make ‘chunky’ cooked eggs. It needs to ‘cook’ the eggs otherwise you would be eating raw eggs.

  4. Yes, this is basically Italian Meringue. You could also do a Swiss Meringue and it would taste very similar and give anyone with misgivings about the egg whites reaching a safe temperature peace of mind.

    • I asked my government-vet brother-in-law about salmonella from raw eggs. He says that salmonella poisoning comes from the egg shells and not inside the egg, so if you wash your eggs carefully before you use them, they should be safe.

    • Kristin: My grandmother makes a Swiss Meringue that I think seems to be about the same. (That IS when you use a hand mixer to beat the icing while it’s in a double boiler, correct?) Keeping the egg whites over the heat for a while makes me much less nervous about food safety!

  5. Is Karo ok to use for this?

  6. I would love to try this, but I am allergic to eggs. Is there anything that I can substitute for the egg whites??

    • Just google “Vegan marshmallow fluff recipe” There are some great ones and because it’s vegan no eggs! :)

    • Yes. I make a Crisco Frosting :
      In sauce pan combine :                                   5 heaping Tbsp. White flour
      1 cup Milk 
      Cook this on top of stove until it thickens. Make sure and keep stirred with a whisk all the time it’s cooking. When done it needs to be Stiff — not liquid—– let cool
      When cool , in mixing bowl add : 
      I whole Crisco stick 
      Mix with electric mixer real well
      Add : 1/12 granulated White Sugar 
      Beat this until not Grainy. When it has mixed really well add your cooled mixture. 
      Start slowly mixing and as it gets all mixed up turn your mixer on HIGH until well blended and fluffy add a cap of Vanilla Flavoring and make sure it’s Fluffy. It is now ready to be used between Chocolate cake layers . Hope you enjoy !!!!

  7. This is same recipe as divinity isn’t it?

  8. Is this a lot like marshmallow cream you buy? I’m wondering if it could be substituted for marshmallows in Rice Krispie treats.

  9. Can this be used to frost between cake layers and on top ?

    • Yes it can be used as frosting. Try flavoing it with any other extract you like. Peppermint, cherry, pineapple, whatever your heart desires! You can also color it! I add my coloring just before I add the hot syrup.

  10. Can this be made with Splenda or any other sweetener?

  11. About how much does this make and can it be doubled? I have six young kids plus I babysit a lot so we go through a jar of fluff fast. Making a big batch would make sense in my house.

  12. Hi! I’m living in Italy and I dearly mis USA style marshmallow. Can’t find corn syrup. Can I double the sugar or substitute honey? Had to buy creme of tartar at the pharmacy!

  13. How long does this keep stored in the refrigerator?

  14. ACtually, it is EXACTLY the same corn syrup as that “icky, evil, yuckerbooboos High Fructose Corn Syrup” you’ve all been brainwashed into believing “causes (insert dire disease here)”. But hey, who’s counting, right?

    • Corn syrup (Karo) is actually glucose. High Fructose Corn Syrup has undergone a chemical process converting some of the glucose into fructose (about 50/50).

      It is true that some brands of corn syrup may have HFCS added but if they do, it will be listed on the ingredients label.

  15. Take a jar of Marshmallow Cream, a container of Cool Whip and whip in a half of box of strawberry jello for a delicious fruit dip. I have been doing this for years.

    • That sounds good! I use a jar of marshmallow crime and a bar of cream cheese, stir together until smooth. Makes a great dip for strawberries – especially early in the season when they are not quite at their peak and need a little sweetening.

  16. How long does this recipe save? We are down in Australia and this is not easily accessed (as well as corn syrup) I’d like to be able to make some to have on hand. Thanks!!

  17. Hi Holly

    Thank you for sharing this recipe. What I am wanting to know is if I frost a cake with this fluff, will it dry hard if being served the next day? I am scared it will get hard or tacky.

    Thank yo so much

  18. how long will this last in a jar?

  19. Just put it in a pressure cooker with water 1/2 inch above the can and cook for 35 minutes. No fuss no clean up and no worrying about the water level etc… I even cook 2 cans at once without a problem.

  20. This is a recipe my Mo used to ice a very special cake she use to make. Bake a white cake, cool, then between the two layers fill with apricot jam. Ice with the fluff, then add coconut to top and sides….Never lasted longer then a day!

    • That sounds wonderful Patty! Thank you for sharing!

  21. Sounds really good. I’ve never made it and was wondering how you would use it.

  22. Just made this earlier today to use in a homemade chocolate peanut butter fudge recipe. Had absolutely no problem. It came out great! Tastes light and fluffy even though it is thick and sticky. Taste so much better than store bought and not as cloyingly sweet. Was easier making this than it was trying to get it in a mason jar lol!

  23. Hi Holly,

    I’m not familiar with golden corn syrup. Is this the same as a product such as Lyle’s golden syrup? Or is it just light Karo syrup? Thanks!

    • Light Karo is perfect in this recipe.

    • Lyle’s Golden is sugar cane syrup, tastes way better than corn syrup (more like liquid brown sugar) and often works as a superior tasting substitute for corn syrup. I would try it and see. Some US grocery stores are finally starting to carry it, but mostly I have seen it in Great Britain.

  24. I’m not rich enough to afford a stand mixer, can you use a hand beater?

  25. How long does this keep?

  26. How much does this recipe make ?

  27. Hi,

    Your recipe mentions 2 tablespoons of sugar & 2/3 cup of granulated sugar. Are they both the granulated sugar? Or 2 different types?


  28. There is “sugar” listed and “granulated sugar” what is the difference? Also what is golden syrup?

    • Each sugar refers to granulated sugar and corn syrup is the same as Karo syrup. Hope that helps.

  29. This is an excellent Recipe! However, my husband is allergic to corn, so I used Lyle’s Golden Syrup, which is a sugar cane syrup. Has a very rich flavor, about the same level of sweetness, a bit more expensive but works great and can be used to substitute for corn syrup in any recipe. If you wanted a flavor twist, use maple syrup.

  30. Could I substitute Maple syrup for the corn syrup – the real stuff, not pancake syrup?

  31. I plan to top hot cocoa with this recipe. Can’t wait! 

  32. Loved, loved this recipe,  It came out perfect all I can say is YUM!  Thank you for sharing it.
