Share to save for later!

One of everyone’s most favourite desserts that not only children love are marshmallows. You probably remember having s’ mores as a kid.

It’s well known that store-bought marshmallows are extremely high in carbohydrates, artificial additives and sugars. This means you’ll need to avoid them on a low-carb diet or learn how to make keto marshmallows.

This time I want to introduce you to a recipe that features low carb marshmallows, they are sugar-free and contain almost zero carbohydrates. These homemade marshmallows will bring pleasure to your whole family!

low carb raspberry and vanilla marshmallows

I used granulated gelatin as a base. It dissolves quickly and provides a higher density and viscosity. 

You need to whisk hot water with granulated gelatin and combine with erythritol sweetener (one of the keto sugar alcohols) dissolved in water. Divide this mixture between two bowls and add flavourings. 

This low carb marshmallow recipe is terrific because it contains almost zero carbs. This is due to the use of natural extractions, such as vanilla and raspberry. Just make sure the extracts you use has no added sugars.

You can choose the flavours that you like best, but don’t forget to use only natural ones. In this recipe, I add pure vanilla extract and pure raspberry extract. 

After adding flavours, use a hand mixer and beat each mixture until fluffy. Spoon mixture into silicone ice cubes mold and transfer to the fridge to set.

Once they are set, gently unmold marshmallows and enjoy. (You can use a lined dish instead of silicone ice cubes mold. In this case, you need to cut marshmallows into squares with a sharp knife after mixtures are set).

You can not roast low-carb marshmallows like you would with traditional marshmallows. They don’t contain any sugar, so this kind of marshmallows will collapse when they heat. Enjoy them as they are!

How to Make Low Carb Sugar Free Marshmallows

For this sugar free marshmallow recipe, I used erythritol instead of sugar. The first step is to dissolve this powdered sweetener in hot water.

Whisk together gelatin and hot water in a separate bowl.

Divide the mixture into two bowls and add your choice of extract to each one. In this recipe, I use raspberry in one bowl and vanilla in another.

Spoon the mixture into ice cube molds and freeze to allow the marshmallows to set.

Can you eat marshmallows on a keto diet?

Regular marshmallows are not keto-friendly as they are made primarily of sugar and corn syrup, which are high in carbohydrates. For a keto diet, you would need to find specialty marshmallows made with keto-approved sweeteners (such as monk fruit and stevia) that have a low net carb count. My recipe has 0 net carbs per serving.

What can substitute for gelatin in marshmallows on keto?

For a keto-friendly marshmallow, you can use agar agar powder, which is a popular gelatin substitute derived from seaweed. It’s plant-based and has almost zero net carbs, making it suitable for a keto diet. Otherwise you might try fish gelatin.

How to store homemade marshmallows

To store homemade keto marshmallows, coat them with a keto-friendly powdered sweetener, place them in an airtight container with layers separated by parchment paper, and keep them in a cool, dry place for up to three weeks. Avoid refrigeration to prevent stickiness, but they can be frozen for longer storage.

How long can you store keto marshmallows?

Keto marshmallows can typically be stored in an airtight container at room temperature for up to three weeks. If you need to store them for a longer period, they can be frozen for several months. Just be sure to thaw them properly at room temperature before consuming to ensure the best texture.
