Have you ever tried homemade marshmallows? If not, they are not only easy but beyond anything you’ve ever had from the store! Soft, pillowy, and perfectly dreamy, a good homemade marshmallow is just pure bliss! I’ve made the vanilla ones several times, for both hot cocoa and s’mores. They’re always a hit, don’t worry that recipe will be shared soon. Today I’m sharing my fun “Valentine” version: strawberry heart marshmallows.
For this recipe, I wanted the pink on the marshmallows to be subtle since I was planning on covering the outside with freeze dried strawberries as well. To get the strawberry flavor, I used Dolce Flav Strawberry Extract.

I decided to lower the amounts so you’re not stuck with a bunch of marshmallows, but if you want more AND want them thicker, just double or triple the amount.

MARSHMALLOW BASICS
While making homemade marshmallows is a technical process, it’s honestly much easier than you think! Here’s a breakdown of the steps:
- Bloom the gelatin. Pour cold water over the gelatin in a large mixing bowl and mix it on low for about 30 seconds. This process is called blooming the unflavored gelatine. Essentially, you’re softening the unflavored gelatine, giving it a head start to easily dissolve into the marshmallow mixture. This ensures a smooth texture.
- Making the sugar syrup mixture. To make the sugar syrup, whisk and heat corn syrup, sugar, water, flavoring/extract of choice, a pinch of salt, and in this case the strawberry powder, in a medium saucepan over medium-high heat. Bring to a boil and let it boil for about 1 minute.
- Mix it all together. Use an electric mixer (I use my stand mixer, but if all you have is a hand mixer, use that). Slowly (and carefully!) drizzle the sugar syrup mixture into the mixing bowl with the mixer on low speed. Once all is added, increase to medium-low speed for about 2 minutes. Increase the speed to high, and continue beating until the mixture becomes very fluffy and almost triples in size (about 10 minutes).
- Make your marshmallows. Then immediately transfer to a baking dish and let set for 2 hours.




PREPPING AHEAD IS KEY
One of the keys to success when making these strawberry marshmallows is prepping all of your ingredients and equipment before you begin cooking. The active portion of marshmallow-making moves very quickly so make sure to complete the following steps before you begin:
- Line a baking dish with lightly greased parchment paper. Tip: use binder clips to keep the parchment paper down.
- Make the marshmallow dusting powder: Use 2 teaspoons of cornstarch and 1 oz (minus 2 teaspoons) of freeze dried strawberry powder. This is what you’ll use to coat the marshmallows to prevent them from sticking together.
- Prepare the freeze dried strawberries. Grind the freeze-dried strawberries into a powder. For a super smooth texture, I recommend using a coffee grinder. A food processor also works, just note: the powder won’t be as fine. You can also just buy freeze dried strawberries
- Have your electric mixer ready to go. Trust me. Once that sugar mixture is ready, it’s ready. I use my stand mixer, but if all you have is a hand mixer, that will work just as well.


COOKING WITH KIDS
DISCLOSURE: Please keep in mind that the following tips are general and are meant to be suggestive. I personally use these strategies with my own kids, who are all unique even within my own family of five. Therefore, please regard these as suggestions or ideas. If you feel that your child requires more or less assistance, then go with what you and your child are comfortable with. Ultimately, you know your child best.
Of course, for safety, some things should be done by adults (the sugar syrup for example should be handled by an adult). But blooming the gelatin, or cutting the marshmallows, can definitely be done by your kids of various ages. I did this project with my 7, 5, and 3 year-olds.
LET’S MAKE THEM INTO HEARTS
I’m using this heart-shaped cookie cutter from this Thyme & Table Stainless Steel Cookie Cutter Set to make these cute marshmallows perfect for Valentine’s Day. Of course, use any shape you’d like or just cut them into squares. Just make sure that your cookie cutter or knife is well-oiled to prevent any sticking.





JENN’S TIP
if you cut your marshmallows into 2×2 inch squares you should get 12 marshmallows. Making the heart marshmallows I got about 20 with a good amount of scrap marshmallows, which honestly, was eaten rather quickly in my house. But of course, numbers will vary based on the size of your squares/hearts and how you cut them out (I always go for minimum “waste”).
STORAGE DETAILS
Marshmallows can be stored for up to several weeks at room temperature. They should be well coated in the dusting powder (a mixture of cornstarch and powdered sugar/freeze-dried strawberry powder) and kept in an airtight container.

Marshmallows are all about texture. I don’t recommend freezing them. They can take on a bit of a mushier texture as they thaw. But really it all depends on how you’ll use your strawberry marshmallows. If you’re planning to toss them in some hot cocoa or s’mores, a slight change in texture won’t be a huge deal breaker (since they’ll melt anyways) so go ahead and try freezing!
