Marshmallow Conversions

I can’t tell you how many times I’ve Googled “how many marshmallows in a cup” or “ how many mini marshmallows in a regular” or better yet, “is marshmallow crème and marshmallow fluff the same thing?”

It’s the type of stuff I know in the moment and then it just floats out of my head. So, I created this very quick cheat sheet as my own resource and I hope others find it helpful too.

If you need a quick peek, they are broken down into sections, but if you want a printable image, it is all the way at the bottom. Just keep scrolling.

Before we get started, let’s make sure we are on the same page. There are three generic sizes of marshmallows: mini, regular and jumbo.

One thing to keep in mind is that nearly any recipes that calls for marshmallows is forgiving in volume and size. Very few cannot be converted or will be ruined if you use too little or too much. Is there even such a thing as too much marshmallow?

Mini Marshmallows

Mini marshmallows are excellent to keep around the kitchen. They melt easier and faster because of their smaller size and can also easily be converted to recipes that require regular or jumbo.

Also use them for topping hot chocolate, sweet potatoes, decorating cookies and cupcakes and more. Who doesn’t want puffy little clouds?

10 ounce bag = 5 1/2 cups = 40 regular size
16 ounce bag = 8 ½ cups = 63 regular size
2 cups minis = 1 cup crème/fluff
50 minis = 1 cup
14 minis = 1 regular
56 minis = 1 jumbo

Regular Marshmallows

Regular size is the original size of marshmallow and probably what comes to mind is making s’mores. They are great for things that would require larger bites and toasting.

The regular size can also be cut into discs for decorating and into smaller squares for easier melting and distribution.

16 ounce bag = 8 cups = 64 marshmallows
8 regular = 1 cup
4 regular = ½ cup
1 regular = 14 minis
1 cup regular = ½ cup crème/fluff

Jumbo Marshmallows

Jumbos can be tricky to find and aren’t available everywhere. They are awesome for giant s’mores and more of a novelty item. Like regulars, they can be trimmed down should you need smaller portions.

24 ounce bag = 4 cups = 26 marshmallows
1 jumbo = 4 reg = 56 minis
1 jumbo = ¼ cup crème/fluff

Marshmallow Crème/Fluff

Crème and fluff are the same darn thing! And guess what, they are more like meringue than they are solid marshmallows. To make these at home would require egg whites, corn syrup, cream of tartar, sugar and vanilla. But you can also melt down marshmallows and it will work the same way.

Crème and fluff are great for dessert dips, pies, frosting and layer cakes. Also use them slathered onto a peanut sandwich for extra special events.

They can even be used in place of marshmallows for Rice Krispie treats and such, you’ll get a little more chewy/soft result. Loose rule is to double the amount of real marshmallows for the amount of fluff you need for regulars. You might need to slightly alter recipes to make it work.

7 ounces creme/fluff = heaping 1 ½ cups
18 ounces = 3 ½ cups
½ cup crème = 1 cup minis
½ cup crème = 1 cup reg
½ cup crème = 2 jumbos

Loose rule is to double the amount of real marshmallows for the amount of fluff you need for regulars.

Questions and Reviews

  1. What is the difference between dehydrated mini marshmallows and mini marshmallows? If a recipe calls for one, can you substitute it with the other and still use the same amount? For example, instead of using one cup of dehydrated ones, can you use one cup of the mini ones instead?

    1. The dehydrated ones are smaller and crunchy because they don’t have any moisture. They don’t melt, so they can’t be swapped, unfortunately.

    1. I’ve gotten mine at the regular grocery store (in a shaker, not a bag), but also seen them at the craft store.

  2. This is good information.
    Having an inexpensive kitchen scale is excellent.
    We use 7oz. of marshmallows in place of 7 oz. of marshmallow cream for fantasy fudge. Either regular or mini work. Mini melts faster. This is neater and quicker than using fluff.

    Make a habit of weighing your measured volume ingredients and noting the weight on your recipe for future use.
