Homemade Miette Marshmallows

May 4, 2015

Marshmallows are just magical. They’re transformed into soft pillow-y and chewy sweets from a simple list of ingredients: sugar, gelatin and egg whites. There’s also a world of difference between homemade and store-bought marshmallows and if you haven’t had homemade marshmallows, I’d get to making these immediately! However, marshmallows are deceptive in their simplicity as working with egg whites and hot sugary syrup can get tricky. I can attest to this as I’ve attempted to make marshmallows at home a couple times only to have the whole thing end in a sticky mess. So who better to walk me through all the detailed steps than Meg Ray, owner of Miette — one of my favorite bakeries to visit in San Francisco (Tip: Meg makes the best macarons in my opinion). Now with the weather warming up, I’m going to be giving these a go for s’mores!

Removing marshmallows




  • 1/2 cup (1 1/2 ounces) cornstarch
  • 1/2 cup (1 3/4 ounces) sifted powdered sugar
  • 6 gelatin sheets
  • 2 cups of cold water
  • 2 cups (14 ounces) granulated sugar
  • 1/2 cup of light corn syrup
  • 1/2 cup of water
  • 1/2 vanilla bean
  • 3 large eggs
  • 1 tablespoon vanilla extract
  • pinch of cream of tartar
  • 1/4 teaspoon kosher salt


  • Have ready a 9 by 13 inch pan lightly coated with cooking spray (or you can use small round silicone molds that Meg uses). In a small bowl, stir together the cornstarch and powdered sugar. Dust the bottom and sides of the pan with the cornstarch mixture. Tap off the excess and reserve.
  • In a medium bowl, submerge the gelatin sheets in 2 cups of cold water. Set aside to soften.
  • In a medium saucepan, combine the granulated sugar, corn syrup and 1/2 cup of water. Cut the vanilla bean in half lengthwise and scrape the seeds into the sugar. Clip a candy thermometer to the side of the pan. (Meg suggests this candy thermometer). Over medium-low heat, cook the mixture to 246 degrees F.
  • Meanwhile, in the bowl of a stand mixer fitted with a whisk attachment, combine the egg whites, vanilla extract, cream of tartar and salt. When the syrup reaches 230 degrees F, start to whisk the egg whites on low speed. When it reaches 246 degrees F, immediately remove the syrup from the heat and whisk in the softened gelatin until no lumps remain. Pour the syrup into a heat proof pitcher or something with a spout if necessary.
  • With the mixer still on low speed, pour in a small amount of the syrup, away from the whisk so that the hot syrup does not splash. Continue to add the syrup in a thin stream; when all the syrup has been added, raise the speed to medium high. Continue to whisk until the meringue has cooled to room temperature and stiff peaks form. Scrape it out into a prepared pan and smooth the top. Dust the top with some of the remaining cornstarch mixture. Cover the pan and allow the marshmallows to set for about 6 hours.
  • To cut, slip an offset spatula between the marshmallow and the sides of the pan. Invert the slab onto a cutting board dusted with the cornstarch mixture. Using a lightly oiled knife, cut the marshmallows into 1 1/2 inch squares. Dust the cut edges with the cornstarch mixture and store in an airtight container or bag for up to 5 days.

Thank you. These look awesome. I’m going to try these. Can you please give more information (specifics) on making/using the silicone molds (spray? Etc); your recipe is more about a traditional way, ie large pan; but not specific in the silicone molds process. Thank you very much.

do you have to spray silicone mold? what about the marshmallow hardening in the bag? thanks!

Also, quick clarification-the recipe calls for- 2 (14 ounces) granulated sugar. Can you tell me what is meant by that measurement please?

Hi! I love marshallows too! I want to use this recipe, however I cannot purchase sheets of gelatin locally. Can you suggest the amount of Knox Gelatin I would use instead?

Unfortunately, I’m not sure if you can use Knox gelatin– I’ve never tried it with that, but you can order gelatin sheets online!

I make marshmallows with same ingredients except I use 3 pkgs Knox gelatin. Comes out perfect. Making without egg whites (French Marshmallows) is easier and they set well. Also score with a ruler and marshmallow can be cut with good set of scissors.


This looks great! would you tell me the nutricional facts? I have some food-issues so I would love to know the nutricional table.


Hey Karen!
Thats a wonderful recipe, thanks for sharing.
I did have a quick question though – how easy or difficult was it to pipe the mixture into the silicon moulds?
So, if I was to make a batch and pipe them into the moulds instead of the one single pan, would the mixture not start becoming thick inside the piping bag? Also, did you spray oil the inside of the piping bag just so the mixture came out easily?


I’ve always wanted to make marshmallows. However, is it possible to use agar agar instead of the gelatin sheets? and if so, how much agar agar would one need for this recipe?


I recently made homemade marshmallows for the first time. I added coconut extract. My instructions did not call for egg whites but thy turned out super delicious! I found that I made too much to eat so I melted them down a couple days later and made rice crispy treats. It was so good. Next time I will add egg whites.

I was interested in knowing how long these last for? I was thinking about making some, but I dont have much of a sweet tooth and usually freeze my chocolate.. what would you suggest?

There is really nothing like a homemade marshmallow, I agree, they’re definitely like magic. I love the step-by-step tutorial!

I live homemade marshmallows, the first time I made them with egg whites and the second without. I definitely prefer the egg white version. Never thought about putting in molds.
