Homemade Marshmallows
What are marshmallows
Marshmallows are a confection made by stabilizing whipped sugar syrup with gelatin or similar gelling agents. Traditional marshmallows were originally made from the root of the marshmallow plant, but modern versions use gelatin for structure.
Homemade marshmallows are softer, fresher, and less chewy than commercial ones.
Ingredients (Makes one 8×8 inch tray)
Base ingredients
- 1 cup cold water (divided into 2 parts)
- 3 tablespoons unflavored gelatin (about 3 packets)
- 2 cups granulated sugar
- 2/3 cup light corn syrup (or glucose syrup)
- 1/4 teaspoon salt
- 1 tablespoon vanilla extract
For dusting
- 1/2 cup powdered sugar
- 1/2 cup cornstarch
Step-by-step instructions
1. Preparing the pan
Line an 8×8 inch or 9×9 inch baking pan with parchment paper.
Lightly grease the paper with oil or butter.
Mix powdered sugar and cornstarch together and dust the bottom and sides of the pan. This prevents sticking.
2. Blooming the gelatin
In a large mixing bowl (preferably the bowl of a stand mixer), add:
- 1/2 cup cold water
- gelatin powder
Let it sit for 8–10 minutes.
This process is called “blooming,” and it allows gelatin to absorb water and soften.
Do not skip this step, or marshmallows will not set properly.
3. Making sugar syrup
In a saucepan, combine:
- 2 cups sugar
- 2/3 cup corn syrup
- 1/2 cup water
- salt
Heat over medium heat while stirring until sugar dissolves.
Once dissolved, stop stirring and let it boil.
Use a thermometer and cook until the syrup reaches:
- 115°C to 118°C (soft-ball stage)
This step is critical for marshmallow structure.
4. Combining syrup with gelatin
Turn on the mixer on low speed.
Slowly and carefully pour the hot syrup into the bloomed gelatin.
The mixture will be very hot, so pour steadily but safely.
Once all syrup is added, increase speed to high.
5. Whipping the marshmallow mixture
Beat the mixture for 10–15 minutes.
During whipping:
- It will become thick
- Then fluffy
- Then glossy and white
- Volume will increase significantly
Add vanilla extract near the end of whipping.
The final texture should be thick, sticky, and marshmallow-like.
6. Pouring into pan
Quickly pour the mixture into the prepared pan.
Use a spatula lightly greased with oil to smooth the top.
The mixture sets fast, so work quickly.
7. Setting
Let marshmallows sit at room temperature for 6–8 hours or overnight.
Do not refrigerate, as it can make them sticky or sweaty.
8. Cutting marshmallows
Dust a clean surface with powdered sugar and cornstarch mixture.
Turn out the marshmallow slab onto the surface.
Use a sharp knife (greased or dusted) to cut into squares.
You can also use scissors for cleaner cuts.
9. Coating
Toss cut marshmallows in powdered sugar mixture to prevent sticking.
Shake off excess.
Texture profile
Homemade marshmallows are:
- Soft and airy
- Lightly chewy
- Spongy and melt-in-mouth
- Much fresher than store versions
Serving suggestions
Marshmallows can be used for:
- Hot chocolate topping
- S’mores
- Baking desserts
- Eating as a sweet snack
- Decorating cakes
Variations
1. Chocolate marshmallows
Add cocoa powder during whipping stage.
2. Strawberry marshmallows
Add strawberry puree or flavored extract.
3. Coffee marshmallows
Add instant coffee dissolved in syrup.
4. Vegan marshmallows
Use agar-agar instead of gelatin (texture slightly firmer).
5. Colored marshmallows
Add food coloring during whipping stage.
Common mistakes
- Not blooming gelatin properly
- Overheating or undercooking sugar syrup
- Not whipping long enough
- Pouring syrup too slowly or too fast
- Cutting before fully set
Tips for perfect marshmallows
- Use a candy thermometer for accuracy
- Grease spatula and knife to prevent sticking
- Whip long enough until mixture is very thick and fluffy
- Let it cure overnight for best texture
- Work quickly once syrup is ready
