If you follow a Keto Diet, you already know that marshmallows are sugar bombs and not Keto-friendly because their high levels of carbohydrates can quickly spike blood sugar and kick you out of ketosis. However, you can eat sugar free marshmallows on a Keto Diet. Let’s find the best brands and easiest recipes to make homemade Keto-friendly sugar free marshmallows.

What Are Sugar Free Marshmallows?

Sugar free marshmallows are a low-carb alternative to traditional marshmallows that contain non-glycemic or low-glycemic sweeteners instead of cane sugar and corn syrup.

Instead of sugar, they use ingredients like monk fruit extract, allulose, erythritol, stevia, or blends of these sweeteners to keep carbohydrates low and be Keto-friendly.

The base structure of marshmallows remains the same: gelatin provides structure and fluffiness, while sweeteners supply sweetness and bulk.

Many Keto versions also include prebiotic fiber or soluble corn fiber to improve texture and reduce net carbohydrates.

Unlike regular marshmallows, sugar free marshmallows are formulated to have very low net carbs, usually about 0-3 grams per serving.

This means if you eat them in controlled portions, you can have them even on a Low-Carb Diet or Keto Diet without damaging your daily macro goals.

Ingredients in Keto Sugar Free Marshmallows

To make sugar free marshmallows, you need:

  • Gelatin
  • Water
  • Monk fruit or stevia
  • Allulose or erythritol
  • Prebiotic fiber or soluble fiber
  • Natural flavors (vanilla, etc.)

But you need to steer clear of the following ingredients because they can raise blood sugar levels and are not Keto-friendly:

  • Maltitol
  • Dextrose
  • Tapioca syrup
  • Maltodextrin
  • Cane sugar or corn syrup

Before learning about the recipe and instructions, let’s find out what nutrients we can get from sugar free marshmallows by including the good ingredients.

Nutrients in Regular vs. Sugar Free Marshmallows

If you are still dubious whether sugar free marshmallows are Keto-friendly or even better than regular variations, let’s take a look at the table below that shows the nutritional difference between regular and sugar free marshmallows.

Feature/ TypeRegular MarshmallowsStore-Bought Sugar Free Marshmallows (Keto)Homemade Sugar Free Marshmallows (Keto)
Serving Size 4 large 4 large 4 large
Calories 90 kcal 40-60 kcal 35-50 kcal
Total Carbs 23 g 10 g 6 g
Fiber 0 g 8-9 g 5 g
Net Carbs 23 g 1-2 g 1 g
Sugar 21 g 0 g 0 g

As the table above shows, the net carbs of sugar free marshmallows, whether store-bought or homemade, are lower than the net carbs in regular ones.

Net carbs are calculated by subtracting fiber and certain sugar alcohols from total carbs: Net Carbs = Total Carbs – Fiber – Sugar Alcohols

Since most ketogenic diets aim to stay between 20-30 grams of net carbs per day, sugar free marshmallows are considered Keto-friendly.

Can You Eat Sugar Free Marshmallows on a Keto Diet?

  • Yes, sugar free marshmallows can fit into a Keto Diet when:
  • They contain Keto-friendly sweeteners
  • Net carbs are low (under 2g per serving)
  • You control portion sizes

However, please note that even Keto-friendly treats can slow fat loss if eaten excessively. Think of sugar free marshmallows as an occasional treat, not a daily routine.

Portion Guidance

  • Generally, you can eat 4-6 marshmallows per serving.
  • Pair sugar free marshmallows with protein or fat for better blood sugar control.
  • Track macros if you are in strict ketosis.
