Ingredients & substitutions
To make this simple recipe, you'll need the following ingredients:
- Freeze dried strawberries: the flavor is concentrated in freeze-dried strawberries and there is no added moisture like in fresh strawberries making these ideal for using in this recipe. You'll need a food processor in which to finely grind the strawberries into a powder.
- Water
- Granulated sugar
- Light corn syrup: this helps give homemade marshmallows and homemade marshmallow fluff it's characteristic texture
- Egg whites: use fresh egg whites that have been separated from actual eggs instead of using carton egg whites. Those will not whip up as nicely, if at all. Be sure there is no little bits of egg yolk in the egg whites as this may prevent the egg whites from whipping
- Cream of tartar: this ingredient helps the egg whites whip up into stiff peaks and create that fluffy texture we are going for
- Salt
You will also need a stand electric mixer, a food processor and a candy thermometer to make this recipe.
Food Processor
Mini food processor is the ideal size for using in this recipe.
How to make homemade marshmallow cream
Step 1
To the bowl of a food processor, add the freeze-dried strawberries and grind to a fine powder. You should have about ½ cup. Set aside
Step 2
Place the water, sugar, and corn syrup in a small saucepan, stirring to combine. Warm over medium-high heat until the mixture reaches 240°F on a candy thermometer. This typically takes 10 to 15 minutes. Do not allow it to pass 240ºF
Candy Thermometer
A candy thermometer is necessary for this recipe to ensure the mixture reaches the appropriate temperature.
Step 3
While the sugar is heating, place the egg whites in the bowl of a stand mixer fitted with the whisk attachment. Complete this step as the sugar/corn syrup mixture is coming to temperature so the whipped egg whites are ready once the mixture reaches 240ºF.
Whisk on medium speed until the egg whites are foamy. Increase to high speed and add in the cream of tartar and salt. Continue to mix until soft peaks form.
Soft peaks barely hold their shape. The peaks flop over immediately when the beaters are lifted.
Add in finely ground freeze-dried strawberries and whisk on high speed again until well combined, stopping to scrape the whisk and sides of the bowl as needed
Step 4
Once the sugar mixture reaches 240°F, carefully remove it from the heat and let rest for about 20 seconds. With the mixer running on medium speed, very carefully and slowly stream the sugar mixture into the egg whites.
Turn the speed to high and continue to mix for 7 - 8 minutes, or until the outside of the mixing bowl returns to room temperature and the marshmallow mixture is thick and fluffy

That sounds perfect! Enjoy!!

This looks so delicious. I love freeze dried strawberries anyway. They have such a great flavor. I'm making this for the 4th of July BBQ. just in time too, Thank you for this awesome recipe.
Kimberlee Ho
Wonderful! Hope you love it!
Grace
This is a great idea! Thank you for sharing!!! My SO is from Maine so we were introduced to fluff long ago. I see some freeze dried blueberries so I need to try making this blueberry flavored. Any tips?
Grace
Kimberlee Ho
So happy you found this recipe! While I haven't tried it, I am going to make an educated guess that freeze-dried blueberries can be substituted in equal amounts for the freeze-dried strawberries. I hope you try it and love it!
Tim
Can this be made sugar free?
Kimberlee Ho
I don't know, I haven't tried to make it sugar free.
Blair
I made this! I followed it to the T using gram measurements - It came out perfect. Like a soft airy marshmallow cloud. Super simple and easy to follow directions. It took a little over 15 minutes to reach 240F, but definitely should use a candy thermometer. If you beat it for a shorter amount of time after adding the sugar syrup you’ve made Italian meringue which is just as delicious. What a great icing/filling/fluff to add to my baking. Thanks!
Kimberlee Ho
This is so helpful, thank you for sharing, Blair! I'm so glad you love this as much as I do 😀.
Blair
Oh I also used this as the filling for some chocolate whoopie pies 🤤 10/10 highly recommend!
Emmi
Is there any reason that using the fresh strawberry juice (strained) and used in place of the water (to make the simple syrup) wouldn’t work ?
For flavor and color.
Kimberlee Ho
I don't know the answer to that, but it's worth a try!
Jennifer Warren
The idea of a whoopie pie, with homemade strawberry marshmallow fluff? Lady, I hope you’re happy with yourself, cause you probably just killed me. (I’m kidding. Mostly. I’m probably mostly kidding lol.) “Thanks for the recipe” is probably what a normal person would say, so let’s go with that. (lol)
Kimberlee Ho
Haha I'm glad this recipe can elicit such a reaction! Enjoy! 😊
Mel Ang
Hi Kim, thank you so much for sharing your recipe. I would like to ask a few technical questions if I may,
1) is this frosting very soft that when piped onto a cookie, it´ll not allow me to stack the cookies in a jar?
2) if it is soft, is there a process to harden it?
I look forward to your answers.
King regards,
Mel
Kimberlee Ho
Hi Mel, yes the frosting is soft. It does not harden at room temperature so I wouldn't recommend stacking the cookies. I'm not sure how to harden it, I'm sorry!
