The best sugar free marshmallows
If you want to make homemade marshmallows without all the sugar but tastes like the real thing, you’ve come to the right place.
There are so many ways to make marshmallows but most of them turn out like white jello or nothing like actual marshmallows. they don’t melt nicely and they definitely don’t dissolve in a hot chocolate or in S’mores.
And that is why I love this sugar free marshmallow recipe: there is no corn syrup and no sugar needed, but they taste incredible thanks to a secret ingredient: allulose.
Allulose is a sugar free and calorie free sweetener that dissolves like white sugar would. It’s popular in keto desserts, like ice cream and caramel. Because of this, it is much better than monk fruit or erythritol, which crystallizes.
Unlike store bought sugar free marshmallows, these don’t leave you with digestive pain or bloating: there are no artificial sweeteners used!
The texture is soft, sticky and spongy, and slightly gooey when it hits your mouth. They are sweet and with a lovely vanilla flavor, without being overpowering.
- Gelatin powder. Unflavored gelatin. Use a good quality powder to ensure there are zero clumps throughout.
- Allulose. You must use allulose to prevent crystallization and the correct texture.
- Water. Tap water is fine. Half will be mixed with the gelatin and the other half will be mixed with the allulose to form a mock syrup.
- Vanilla extract. Gives a lovely vanilla flavor!
- Powdered sugar. Optional, but sift some keto powdered sugar over the top of the set marshmallows!
How to make sugar free marshmallows
Making keto marshmallows follows a simple four-step process and less than 15 minutes hands on time!
The hard part is waiting for them to set, but I promise you, it will be worth every minute.
Step 1- make gelatin
Start by placing half the water into a small bowl and sprinkle the gelatin powder on top of it. Let it sit for 10-12 minutes, for the gelatine to soak up the liquid and become gooey and gelatinous.
Step 2- make the syrup
Next, place the remaining water into a saucepan. Add the allulose and turn the heat to medium. Gently stir the mixture together until it simmers. Stir more vigorously until it boils. Once it is bubbling and boiling, remove it from the heat.
Step 3- make the marshmallows
Now, add the gelatin mixture into the bowl of a stand mixer. At a low speed, turn the mixer on and start beating the gelatine. After 30 seconds, slowly add the boiled water mixture. Add the vanilla extract and mix for 10-11 minutes, or until stiff peaks form.
Step 4- Let it set
Finally, transfer the marshmallow mixture into a lined pan and spread out with a rubber spatula until mostly even. Refrigerate for at least 2 hours until it is firm. Once firm, sift some powdered sweetener on top and slice into pieces.
Tips to make the best keto marshmallows
- If you don’t have a stand mixer, you can also use a hand mixer. The beating time will be slightly longer.
- If your mixture hasn’t formed stiff peaks after 12 minutes, continue beating. The mixture must have stiff peaks!
- Use a slightly wet knife when cutting the marshmallows.
- Switch out the vanilla extract for other flavor options. Peppermint, strawberry, and chocolate extracts are all fantastic options.
How to store marshmallows
Unlike traditional marshmallows, homemade ones shouldn’t be left out at room temperature. Here are best practices for marshmallow storage:
- To store: Keto marshmallows should be stored in the refrigerator in a sealed container, for up to 1 month.
- To freeze: Place leftovers in a ziplock bag and store them in the freezer for up to 6 months.
