Ingredients You’ll Need
- 3/4 cup granulated sugar: This is the base for sweetness and structure in your marshmallows.
- 1/3 cup light (clear) corn syrup: It helps to create the smooth texture and prevents the sugar from crystallizing.
- Pinch of salt: Just a touch enhances the sweetness and balances the flavors.
- 6 tablespoons cool water: Used to activate the gelatin and combine with the sugar syrup.
- 1 packet (2 1/2 teaspoons) unflavored gelatin powder: This is what gives your marshmallows that iconic fluffy texture.
- 1/2 teaspoon vanilla extract: For added flavor, making these marshmallows truly delicious.
- 3/4 cup powdered sugar: This will coat the marshmallows and prevent them from sticking together after cutting.
How to Make Homemade Marshmallows
Prepare the Pan: Start by lining an 8 or 9-inch loaf pan with parchment paper, and spray it lightly with nonstick spray. This ensures easy removal once the marshmallows have set.
Make Sugar Syrup: In a medium saucepan, combine the granulated sugar, corn syrup, salt, and 3 tablespoons of the cool water. Turn the heat to high and bring this mixture to a boil without stirring. Use a candy thermometer and boil until it reaches 238-degrees Fahrenheit.
Prep the Gelatin: While the sugar syrup is boiling, take the remaining 3 tablespoons of cool water and pour it into a large mixing bowl. Sprinkle the unflavored gelatin over the water, allowing it to sit for a few minutes to bloom.
Combine Syrup and Gelatin: Once the sugar syrup reaches the correct temperature, carefully stream it into the gelatin mixture while simultaneously beating it with a hand mixer. Do this slowly to avoid splashing the hot syrup on the edges of the bowl, as it can harden quickly.
Beat the Mixture: Continue beating the mixture for a full 10 minutes. You’ll notice it will become thick and glossy during this time.
Add Flavoring: Stir in the vanilla extract, mixing until it’s fully combined. This step improves the overall flavor profile of your marshmallows.
Spread the Mixture: Pour the marshmallow mixture into the prepared loaf pan. Use a spatula to smooth out the top if needed.
Let Set: Allow the mixture to set uncovered at room temperature for at least 3 hours. This setting time is critical for achieving that perfect marshmallow texture.
Cut the Marshmallows: Once set, sprinkle powdered sugar onto a clean work surface. Gently dump the marshmallows out onto this surface. Use a sharp knife dipped in powdered sugar to cut them into squares, ensuring clean edges.
Coat & Store: Roll the cut marshmallows in additional powdered sugar to coat the edges and prevent sticking. Finally, store them in an airtight container at room temperature where they’ll stay fresh for 2-3 days.
Storing & Reheating
Store your homemade marshmallows in an airtight container at room temperature for up to 2-3 days. If you wish to keep them longer, you can refrigerate them, but be mindful that the texture might change slightly—more chewy than fluffy. For longer preservation, they can be frozen in an airtight container for up to 3 months. If you need to refresh them, let them thaw at room temperature and enjoy as you would fresh ones.
Chef’s Helpful Tips
- Always ensure your gelatin has fully bloomed in the water before adding the syrup; this helps achieve a fluffy texture.
- For sugar syrup, using a candy thermometer is essential for accuracy. If you don’t have one, the soft-ball stage (238 degrees Fahrenheit) is a textured reference point—try dropping a small amount in cold water; it should form a soft ball.
- Prevent sticking by dusting your knife with powdered sugar between cuts, which allows for cleaner slices.
- Feel free to experiment with different extracts (like peppermint or almond) for unique marshmallow flavors.
- If the marshmallows seem too sticky after cutting, give them a light dusting of powdered sugar before storing them.
Homemade marshmallows are not only a treat that’s incredibly easy to make, but they also invite a sense of celebration to any occasion. Whether you’re warming up with a cup of hot cocoa or hosting a s’mores night with friends, these fluffy delights will surely steal the show. Don’t hesitate to adjust flavors or add in your twist to this classic recipe; the possibilities are endless. Enjoy every fluffy, sweet moment!

Recipe FAQs
Can I use flavored gelatin instead of unflavored?
Using flavored gelatin can add a nice twist to your marshmallows, but note that it may also alter the texture slightly. If you go this route, be sure to check the proportions on the package for ratios as they can vary.
Why did my marshmallows not set properly?
If your marshmallows didn’t set, it’s likely that the sugar syrup didn’t reach the right temperature. Using a candy thermometer is the best way to ensure accuracy, avoiding any guesswork.
How can I make my marshmallows hold their shape for longer?
Ensure that you store your marshmallows in an airtight container at a cool room temperature. Avoid humid rooms as moisture can cause them to become sticky.
What else can I do with homemade marshmallows?
Homemade marshmallows can be used in various ways. They’re wonderful melted atop desserts, used in baking recipes, or deliciously toasted over a campfire. You can even crumple them over ice cream for a special treat!
