Marshmallow Conversions

Marshmallow Conversion Chart... All my marshmallow questions ANSWERED!

All your Marshmallow Conversions questions answered in one place with a handy chart you can reference. Bookmark this marshmallow measurement list for future reference!

One of the most frequent questions I get on my site, whether it be on email, in the comments section or on facebook is about marshmallow equivalents. For example, “How many cups of minis is 10 ounces” or “How many regular marshmallows equal a 10 ounce bag of minis?”

Well, you know what? I’ve kind of wondered all that too. I use marshmallows a LOT here on this site…even claiming I have the PERFECT Rice Krispie Treat recipe. Yep, I did.

Anyhow, I do get stuck with some half-used bags of marshmallows from time to time…and without actually weighing them it’s always a guess on if I am actually measuring out enough.

Because let’s be real..marshmallows are hard to measure. One cup of minis to you might be an entirely different thing to me…there’s just so much airspace, you know?

Luckily in most recipes including marshmallows if you go up a few ounces or down a few it doesn’t really affect the outcome too much.

BUT with all that said I wanted to know all the sticky details.

So one day last week I bought ALL the marshmallows in their various sizes, consistencies etc, got my food scale and an arsenal of measuring cups ready and went to work.


It was a dirty job. Literally.

I am still chiseling Fluff off of my dining room table.


What I’ve found for marshmallow conversions is brands are all very consistent in the weights…so don’t worry too much about a Jet-Puffed regular weighing the same amount as a generic brand regular. It does for all intents and purposes.

Also Marshmallow Fluff and Marshmallow Creme are the same. Don’t let anyone tel you different. I might get some opposing views on this, but the only difference I could find was the brand name and the size jar it’s sold in, Creme generally coming in an 7 ounce container and Fluff in an 18 ounce.


Here’s a visual of my findings.

It’s all very scientific…


And this…


You can see by the chart below (and up top) that I have taken all variations of marshmallows and given you their weight and cup equivalents.

You certainly can’t sub in Fluff everywhere you need a melted marshmallow…the consistency is different.

But I have always wondered how much 7 ounces of Marshmallow Creme actually is.

AND let me tell you, once you scoop out the Fluff or Creme it settles and the whipped consistency loses a bit of volume. So all my measurements are after the Fluff settled.

So anyhow, I want you to PIN, bookmark, save, take a screenshot…whatever of this handy little chart. Since you and I are kindred spirits there are a lot of marshmallows in our future!

    So, ,,,,, how many REGULAR marshmallows equals one 7 oz. jar of marshmallow cream?

    How many MINI marshmallows equals one 7 oz. jar of marshmallow cream?

    I am making 2 grasshopper pies. Each pie takes 2 jars. So I need 4 for the 2 pies.

    However I only have 2 jars. BUT I have one bag of reg. marshmallows !

    Just tell me please – I’m exhausted and I still have Christmas wrapping to do. Thank You!

    The largest jar of “Fluff” that I have found is 16 oz which is 1 lb!! That said, this conversion table is still very AWESOME! It sounds like a science experiment my son would love! Anyway, thanks so much!!! 🙂

    I can’t figure out why there’s a 7 oz or a 13 oz jar of marshmallow cream?? I thought 7 and 7 were 14, but Kraft has a new math methodology.

  4. Can we get a 2.0 on thos that doves deeper into the why’s and how’s of measuring and subbing marshmallows? For example: Betty Crocker Grasshopper Pie recipe calls for 32 Large Marshmallows. So to sub that for fluff since we want a kosher recipe, I know it would be 8oz. Or should it be based on volume and instead use the 4 cups? Originally the marshmallows are to be melted, so would that completely change everything?

    Could all of this be solved by making one recipe using different options, or would multiple options be necessary? Why don’t kosher marshmallows melt?

    There’s too many questions in the world and not nearly enough hotels with full kitchens because I am absolutely not doing this kind of experimenting at home unless I have Dexter plastic wrap everything first.

    Also: I’m really looking forward to perusing your blog because I never would have thought to combine chocolate, marshmallows, and popcorn, and that is literally all I want right now.

    I think I love you right now! I’m trying to make marshmallow fondant and the recipe I was given calls for 10oz mini marshmallows…

    Theres a couple of problems with that-
    1- I’m Australian so 10oz means nothing to me.
    2- I’m in northern china, so I had enough trouble trying to find regular marshmallows, so forget mini marshmallows.
    3- I’ve failed at making the fondant 3 times already, and I’ve only got 2 small bags left (that I had to travel to the other side of the city to get)… and I really need it to decorate the princess castle cake that I’m making for tomorrow.

    I’ve printed this and attached it to my fondant recipe so I have it for next time.

    Thank you soooo much!

    If one cup of mini marshmallows weighs 2 oz. as stated in the first paragraph then a 10 oz. bag should have 5 cups of mini marshmallows. However the second paragraph states that a 10 oz. bag of mini marshmallows has 6 cups. Which is it?

    1. Shelly

      Marshmallows are difficult to measure in cups for sure. But the 10 ounce bag generally has between 5-6 cups minis depending on how much they are packed down.

        I don’t see my post, but noticed a few errors in copy pasting to my FB account, so I tried reposting, but it looks like it didn’t work. Gosh, I spose I’m making a mess if it…

        I agree the numbers are a bit ‘sticky’ from one package to another! I didn’t even catch the #s discrepancy in the 1st paragraphs, good eye, that’s typically my forte! 😀

        The 10 oz bag of regular marshmallows, anxiously waiting to be whipped into some seriously buttery crispy bars, says 5 mallows equal 1 serving, & there are ‘about’ 9 servings in the pkg, for a grand total of 45 – I’ve yet to count them.

        The recipe we’re looking at calls for 6 c of minis, which I believe was said here to be about 40 regular mallows (not 45 = 5×9). It sounds just about impossible for this 10 oz bag to create 6 c in the 1st place, but I am by no means any kind of mallow expert. 😛

        Hmm this pkg says – in a space separate from ITS recipe – that 38-40 regular mallows = 10 oz, & there are 42 in this particular bag. Well, 41, at last count, as my honey ate one & is likely eating another while I’m out of the kitchen!

        Anyway, as noted, the math is not what many of us grew up with. 😉

        Say! Did you take into account the colored mallows or special flavored ones?!? ahem… Lol

        LOVED reading your recipe & will probably search out your blog as well. 😀

    I am a vegetarian and do not use marshmallows because of the gelatin, however marshmallow cream doesn’t contain gelatin which allows me to make all of those old favorites like s’mores and popcorn balls! My question is how will it work for your Popcorn Cake recipe? Just gooier? I am planning on making it for our next family gathering.
    P.S. Thanks for the conversion chart, this will make my job much easier!!! 🙂

    Goodness, that was a lot of work! You deserve a medal or something. Haha, loved the comment about cute little marshmallow scientist. Now off to check out your perfect rice krispie treats, which I know I will eat the whole pan in one sitting. PS I always want to spell it marshmellow.

  9. I always find these food conversions posts to be some of the most helpful on the net. Must Pin Now!!! I remember reading one about eggs……and thinking to myself. “Duh, of course it makes a difference if you use a medium egg compared to an extra large egg.” I confess, sometimes I just chuck ingredients into the bowl or blender without even measuring all that well! I know, terrible.
