Basic Ingredients

  • 3 tablespoons gelatin powder
  • 1 cup water, divided
  • 1 cup erythritol or your preferred keto sweetener
  • 1 teaspoon vanilla extract
  • Pinch of salt


1. Prepare the Gelatin

  • In a large mixing bowl, combine the gelatin with 1/2 cup of water. Stir well and let it sit for about 10 minutes to bloom.

2. Create the Sweet Syrup

  • In a medium saucepan, combine the remaining 1/2 cup of water, erythritol, and a pinch of salt. Heat the mixture over medium heat, stirring occasionally until the erythritol is completely dissolved. Increase the heat and bring the mixture to a boil. Allow it to boil for about 2-3 minutes, then remove from heat.

3. Combine Gelatin and Syrup

  • Slowly pour the hot syrup into the bowl with the bloomed gelatin while mixing on low speed. Gradually increase the speed to high and continue mixing for about 10-15 minutes, or until the mixture is thick, fluffy, and has doubled in volume. Add the vanilla extract during the last minute of mixing.

4. Mold the Marshmallows

  • Line a 9×9 inch baking dish with parchment paper and lightly grease it with a keto-friendly oil. Pour the marshmallow mixture into the prepared dish and spread it evenly using a spatula. Let it sit at room temperature for at least 4 hours or until set.

5. Cut and Serve

  • Once set, lift the marshmallow slab out of the dish using the parchment paper. Use a greased knife or pizza cutter to cut the marshmallows into desired shapes and sizes. Store in an airtight container at room temperature.

Tips for Perfect Keto Marshmallows

1. Use a Quality Gelatin

Ensure you’re using a high-quality, unflavored gelatin for the best texture and flavor. Avoid flavored or sweetened gelatins as they may contain added sugars and carbs.

2. Monitor the Syrup Temperature

When creating the sweet syrup, be careful not to overheat it. Boiling the mixture for too long can cause it to become too thick, making it difficult to combine with the gelatin.

3. Customize the Flavor

Feel free to experiment with different flavor extracts to customize your marshmallows. Peppermint, almond, or coconut extracts can add a fun twist to the classic vanilla flavor.
