Marshmallow Calories: Quick Answer
Let’s start with the numbers most people are searching for:
- 1 regular marshmallow: ~23–25 calories
- 1 mini marshmallow: ~2–3 calories
- 1 jumbo marshmallow: ~45–50 calories
- 100g marshmallows: ~318 calories
At first glance, marshmallows seem low in calories. However, because they are light and easy to eat in large quantities, the calories can add up quickly.
Marshmallow Calories by Serving Size
Understanding portion size is key when evaluating marshmallow calories.
Calories in 1 Marshmallow
A standard marshmallow weighs about 7 grams and contains roughly 23–25 calories, mostly from sugar.
Calories in Mini Marshmallows
Mini marshmallows are commonly used in hot chocolate and desserts:
- 1 mini marshmallow: ~2–3 calories
- 1 cup mini marshmallows: ~150–160 calories
Because they’re small, it’s easy to consume large amounts without realizing it.
Calories in Jumbo Marshmallows
Jumbo marshmallows often used for roasting contain:
- ~45–50 calories per piece
These are typically used in s’mores, which significantly increases total calorie intake.
Calories per 100g Marshmallows
- ~318 calories per 100g
This puts marshmallows in a similar calorie range as many other sugary snacks.
Marshmallow Nutrition Facts
Calories are just one part of the story. Let’s look at what marshmallows are actually made of.
Macronutrients Breakdown
- Carbohydrates: ~80g per 100g (mostly sugar)
- Protein: ~1–2g (from gelatin)
- Fat: 0g
Marshmallows are fat-free, but extremely high in sugar.
Sugar Content in Marshmallows
- ~28–30g sugar per 100g
- Nearly all calories come from simple sugars
This means marshmallows can cause quick spikes in blood sugar levels.
Micronutrients

Why Marshmallow Calories Add Up Quickly
One of the biggest misconceptions about marshmallow calories is based on perception.
1. The “Light and Fluffy” Illusion
Marshmallows feel light, but they are still dense in sugar. Eating 5–6 marshmallows can easily exceed 120 calories.
2. Easy to Overeat
Unlike heavier desserts, marshmallows don’t create a strong feeling of fullness, making it easier to overconsume.
3. Hidden Calories in Drinks & Desserts
Adding marshmallows to:
- Hot chocolate
- Coffee
- Desserts
…can silently increase your daily calorie intake.
