I’ve tried every healthy marshmallow brand, and most look and taste like white jello. Mine are pillowy soft with plenty of vanilla flavor, and they won’t turn to mush when you fold them into my rocky road fudge.

★★★★★ REVIEW
“These were fabulous!! These seriously taste like real deal marshmallows” – Holland
Ingredients needed
- Gelatin powder. Unflavored gelatin. Use a good quality powder to ensure there are zero clumps throughout.
- Allulose. I highly recommend allulose over monk fruit, erythritol, or other sugar alcohols as I’ve found it to be the most reliable and prevent the marshmallows from crystallizing.
- 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
I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.
Step 1- Prep work. Line an 8×8-inch pan with parchment paper.
Step 2- Set the gelatin. In a small bowl, add half of the water and gelatin powder. Let it sit for 10 minutes for the gelatin to soak up liquid and become gooey.
Step 3- Boil. In a small saucepan over medium heat, bring the remaining water and sweetener to a simmer. Stir often until boiling. Let it boil for several minutes before removing from the heat.
Step 4- Whip. Add the gelatin mixture to the bowl of a stand mixer with a whisk attachment. On low speed, mix for 30 seconds. Slowly add the boiling water mixture along with the vanilla. Beat for 10-12 minutes or until stiff peaks form.
Step 5- Chill. Transfer the marshmallow mixture to the pan and use a rubber spatula to smooth it into an even layer. Refrigerate for 2 hours or until set. Once set, cut into pieces and dust with powdered sweetener.
Arman’s recipe tips
- Use a hand mixer instead. If you don’t have a stand mixer, you can use an electric mixer, though the beating time will be slightly longer.
- Get those stiff peaks! If your mixture hasn’t formed stiff peaks after 12 minutes, continue beating. You’ll get there!
- Swap the extracts. Try almond extract, peppermint extract, chocolate extract, or strawberry extract.
- Add food coloring. As you’re mixing, drop in a few drops of food coloring.
- Don’t worry if they’re not perfect. Homemade marshmallows are supposed to be rustic, so don’t fret if they’re a little misshapen.

Frequently asked questions
Most sugar-free desserts or snacks are suitable for those with diabetes. My father, who has type 2 diabetes, regularly enjoys these as part of his diet. However, it is always best practice to speak with a certified medical professional before changing anything in your diet.
These marshmallows are fabulous for a keto diet, with less than 1 gram of net carbs per serving. They are one of the lowest-carb candy recipes you’ll ever make.
