The Importance of Weighing Your Ingredients
In baking, precision is paramount. While counting marshmallows might seem straightforward, relying on the number alone can lead to inconsistent results. Brand variations, individual marshmallow size discrepancies, and even packaging can all affect the total weight. For perfect marshmallow-based treats like Rice Krispie treats, fudge, or s'mores, using a digital kitchen scale is the best practice. This ensures the correct ratio of marshmallows to other ingredients, leading to the perfect texture and sweetness every time.
Factors That Influence Marshmallow Weight
Not all marshmallows are created equal, and several factors can influence how many grams are 4 marshmallows:
- Size and Type: Marshmallows come in various sizes, from mini to jumbo, and each has a different weight. Four mini marshmallows will obviously weigh far less than four large ones. Some brands even offer 's'mores' specific marshmallows, which are flatter and denser.
- Brand Variation: Different brands use different formulations and production methods, which can affect the density and weight. For example, some brands may pack their marshmallows more densely than others. Always check the nutritional information on the packaging for the most accurate serving-size weight.
- Density: The airiness of a marshmallow is a key characteristic. A fluffier marshmallow will weigh less than a denser one of the same size. Homemade marshmallows, for example, can have a different density profile than store-bought ones.
- Moisture Content: Over time, marshmallows can dry out, which changes their weight slightly. While not a significant factor for fresh marshmallows, it's something to consider for older stock.
How to Measure Marshmallows for Recipes
For those without a kitchen scale, here is a helpful list for converting marshmallows:
- For mini marshmallows: Approximately 10-12 minis are needed for every 7 grams or one regular-sized marshmallow. A half-cup of mini marshmallows is roughly 28 grams, equivalent to four large ones.
- For regular (standard) marshmallows: As established, four regular marshmallows equal about 28 to 30 grams. 16 regular marshmallows will weigh around 100 grams, a useful benchmark for many recipes.
- For jumbo marshmallows: A single jumbo marshmallow can weigh between 28 and 30 grams on its own, making it equivalent to four regular marshmallows.
- For a bag of marshmallows: Check the package's net weight. For example, a 16-ounce bag typically holds around 64 regular marshmallows. You can divide the total weight by the total number to find an approximate individual weight.
Comparison Table: Marshmallow Sizes and Weights
| Marshmallow Size | Approximate Weight (Per Piece) | Grams per 4 Marshmallows (Approximate) | Equivalent Measurement | Common Use Case |
|---|---|---|---|---|
| Mini | ~0.7 g | ~2.8 g | About 40-50 mini marshmallows per 1 oz | Hot chocolate toppings, Rice Krispie treats |
| Regular | ~7.2-7.5 g | ~28.8-30 g | 1 cup (packed) = ~1.66 oz (47g) | General baking, fudge, salads |
| Jumbo | ~28 g | ~112 g | One jumbo is about 4 regular | Campfire roasting, large format desserts |
| S'mores | ~14-20 g | ~56-80 g | Depends on size; designed for s'mores | Campfire roasting, chocolate bars |
The Science Behind Marshmallow Weight
Marshmallows are essentially a whipped confection of sugar, water, and gelatin, stabilized by air. The weight of the marshmallow is determined by two main factors: the amount of sugar-gelatin mixture and the amount of air incorporated during the whipping process. A lighter, fluffier marshmallow will have more air and weigh less per volume, while a denser one will have more of the heavier sugar-gelatin mixture. This is why a cup of marshmallows can have a slightly different weight depending on how compactly it's packed or the brand's specific recipe. Professional bakers often rely on weight for this reason, as it's a more consistent metric than volume.
Conclusion
In summary, while the quick answer to "how many grams are 4 marshmallows?" is approximately 28 to 30 grams, the more accurate response depends on the specific size and brand. For precise culinary results, it is always recommended to use a digital kitchen scale. This simple tool eliminates the guesswork and accounts for the natural variations between brands and batches. For general purposes, you can assume that four standard-sized marshmallows will be just under 30 grams, but for baking that demands precision, weighing is the only way to be sure. This knowledge is not only helpful for ensuring your recipes turn out perfectly but also for accurately tracking nutritional information when needed.

Homemade Marshmallow Recipe
For those who want to make their own marshmallows, weighing ingredients is even more critical. Here is a simple recipe to get you started:
Ingredients:
- 1/2 cup cold water
- 3 packets unflavored gelatin (about 21 grams)
- 2 cups granulated sugar
- 1/2 cup corn syrup
- 1/2 cup cold water (for sugar mixture)
- 1/4 teaspoon salt
- 1 1/2 teaspoon vanilla extract
- 1/2 cup powdered sugar
- 1/2 cup cornstarch
Instructions:
- Prep the Pan: Grease and line a 9x13 inch pan with parchment paper. In a small bowl, whisk together the powdered sugar and cornstarch and dust the bottom and sides of the pan generously.
- Soften Gelatin: Pour 1/2 cup cold water into the bowl of a stand mixer fitted with a whisk attachment. Sprinkle the gelatin over the water and let it sit for 5-10 minutes to soften.
- Create Sugar Syrup: In a saucepan, combine the sugar, corn syrup, salt, and the second 1/2 cup of cold water. Stir over medium-low heat until the sugar dissolves. Increase the heat to medium-high and cook until the mixture reaches 240°F (115°C) on a candy thermometer.
- Whip the Mixture: Turn the stand mixer on low and slowly pour the hot sugar syrup into the softened gelatin. Gradually increase the speed to high and whip for 10-15 minutes, or until the mixture is very thick and fluffy. Beat in the vanilla extract.
- Pour and Set: Pour the marshmallow mixture into the prepared pan and smooth the top with a spatula dusted in the powdered sugar mixture. Dust the top with the remaining powdered sugar mixture. Let it sit at room temperature for at least 4 hours, or overnight.
- Cut and Enjoy: Once set, turn the marshmallow block out onto a cutting board. Dust your knife or scissors with the powdered sugar mixture and cut into squares. Toss each square in the remaining powdered sugar mixture to prevent sticking. Enjoy your perfectly weighed and measured homemade marshmallows!
