1/4 cup powdered erythritol (or preferred keto sweetener)
1/4 cup allulose (optional for better texture)
1/2 tsp cream of tartar (optional, for better texture)
Instructions:
Bloom the Gelatin:
In a small bowl, sprinkle the unflavored gelatin over 1/4 cup of water. Let it sit for 5 minutes to bloom.
Make the Syrup:
In a saucepan, combine the remaining 1/4 cup water, erythritol, allulose (if using), and salt. Bring the mixture to a boil over medium heat, stirring to dissolve the sweetener.
Reduce the heat and simmer for about 5 minutes until it thickens slightly.
Whisk the Gelatin:
While the syrup is cooking, gently heat the bloomed gelatin in the microwave for 10-15 seconds to melt it.
Add the melted gelatin to the warm syrup and whisk until fully dissolved.
Whisk the Mixture:
Transfer the syrup mixture into a stand mixer or large bowl. Start whipping on medium speed, adding the cream of tartar (if using) and vanilla extract.
Gradually increase the speed to high and beat for about 10 minutes until the mixture becomes thick, glossy, and forms soft peaks (like marshmallow fluff).
Set the Marshmallows:
Pour the marshmallow mixture into a parchment-lined pan (8×8 works well) and spread it evenly.
Allow it to set at room temperature for 3-4 hours or refrigerate for 1-2 hours to speed up the process.
Cut and Serve:
Once fully set, dust the top with powdered erythritol (optional) to prevent sticking.
Cut into squares and enjoy your keto marshmallows!
Tips:
If you want to make flavored marshmallows, you can add cocoa powder, peppermint extract, or other keto-friendly flavorings to the mixture.
These marshmallows will keep for about a week if stored in an airtight container.
