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.

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

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!

You have no idea how many times I have used this reference! It may be my favorite tool on the internet!

Thank you for this! Ive made rice krispy treats for years and up until very recently the recipe on the bag changed from “1 – 10 oz bag mini marshmallows ” to 5.5 cups mini marshmallows (at least thats what I have always remembered the recipe sayinglol). This threw me wayyy off and that is how I found your page. I also had an experience where I ended up with a 16 oz bag of mini marshmallows and they arrived all kinda stuck together (grocery delivery and very hot outside) so i went insane trying to figure out 5.5 cups… Read more »

You are an angel to have done all that mondo-sticky work to devise the chart of marshmallow equivalent measurements. Thank you so much, Shelly!

I have a dugecrecipe from 50 years ago (grandmas?). What think has happened is the actual marshmallow has become airier over the years and my fudge is so dense and heavy as a brick.

COULD this be because I need to supplement a few more marshmallows to the recipe to make up the added air. VS,. Actual ingredient of an old time marshmallow ?

Please let me know what anyone thinks….

Could someone tell me the calories in the JUMBO size. Bag, either individually (1) or the whole bag. Either size would be helpful.

Concerning mini mallow equivalents, your chart of is a bit confusing. You tell us that 1 cup = 2 oz., and that a 10 oz. bag contains 6 cups. I’ve not actually measured out a 10 oz. bag, but a mathematical equivalent shows that there are five 2 oz. portions in 10 oz. of minis. By using your equivalent of 2 oz. in a cup, that means there are 5 cups in a bag of minis, and I was happy and prepared to start melting my butter. Glancing at the rest of your equivalents, I saw that the chart showed… Read more »

You’re my Krispie Treat hero!! That “ Marshmallow conversion chart” is a true gift to the world! It’s like you read my and knew how confused and In need of help I was!! FYI… I stumbled across your website Bc the “cereal box” said 4 cups of mini’s BUT the “marshmallow bag” said 5 1/2 cups of minis. Very confusing and I’m making these for my new team member at my new job (really want them to be tasty / really want these people to like me, haha. I know, kinda pathetic of me, but it’s true). So I did… Read more »

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!
