Homemade Marshmallow Recipe Without Corn Syrup
Make pillowy, old-fashioned marshmallows at home—no corn syrup needed—with this simple, reliable recipe and expert tips.
There’s something magical about homemade marshmallows—fluffy, light, and worlds apart from the store-bought variety. This recipe skips the corn syrup entirely, relying on classic candy-making techniques to achieve that perfect melt-in-your-mouth texture. Whether you’re topping hot cocoa, making s’mores, or just enjoying a sweet treat, these marshmallows are sure to impress.
Why Make Marshmallows at Home?
Store-bought marshmallows are convenient, but homemade ones offer superior flavor, texture, and customization. You control the sweetness, avoid unwanted additives, and can tailor flavors to your liking. Plus, the process is surprisingly simple—just a bit of patience and attention to detail are needed.
Essential Equipment
Having the right tools makes the process smoother and ensures consistent results:
- Stand mixer (with whisk attachment): Essential for beating the marshmallow mixture to the right consistency. A hand mixer can work in a pinch, but a stand mixer is highly recommended for the 10+ minutes required .
- Candy thermometer: Precise temperature control is crucial for achieving the soft-ball stage (235–240°F), so a reliable candy thermometer with a pot clip is a must .
- 8×8 or 9×13 Baking pan: An 8×8 pan yields thicker marshmallows; a 9×13 pan creates thinner, bite-sized pieces .
- Powdered sugar for dusting: Prevents sticking and adds the classic marshmallow finish.
Ingredients
This recipe uses simple, pantry-friendly ingredients for authentic marshmallow flavor:
- Gelatin powder: 2 packets (unflavored, plain gelatin)
- Water: 1 cup, divided
- Sugar: 2 cups
- Vanilla extract: 2 teaspoons (or substitute with a scraped vanilla bean for extra richness)
- Salt: 1/4 teaspoon
- Powdered sugar (confectioners’ sugar): For dusting the pan and finished marshmallows
Step-by-Step Instructions
Preparation
Before you begin, prepare your pan. Coat the inside of an 8×8 (or 9×13) pan with powdered sugar to prevent sticking. Set aside.
Bloom the Gelatin
- Sprinkle two packets of gelatin powder into the bowl of your stand mixer.
- Pour in 1/2 cup of cold water. Stir briefly to combine, then let the mixture sit while you prepare the sugar syrup. This allows the gelatin to absorb water and “bloom,” which is essential for the marshmallow’s structure.
Make the Sugar Syrup
- In a heavy-bottomed saucepan, combine the remaining 1/2 cup of water and 2 cups of sugar.
- Place the pan over medium heat, stirring until the sugar dissolves.
- Once the sugar has dissolved, clip on your candy thermometer. Increase the heat and bring the syrup to a boil.
- Continue boiling, without stirring, until the syrup reaches the soft-ball stage, which is between 235°F and 240°F (113°C to 116°C)—this is crucial for texture and structure .
Combine Syrup and Gelatin
- When the syrup hits 235°F (113°C), remove it from the heat and let it cool for 1–3 minutes. This prevents the boiling syrup from “cooking” the gelatin when mixed.
- Add vanilla extract and salt to the syrup. Stir gently, being cautious as hot syrup can bubble violently when additions are made.
- Turn your stand mixer with the bloomed gelatin to low speed. Slowly drizzle the hot syrup down the side of the bowl, so it touches the bowl first before mixing with the gelatin. This gradual incorporation prevents lumps and ensures a smooth texture.
Whip to Fluffy Perfection
- Once all the syrup is added, gradually increase the mixer speed to high (or one to two notches below maximum, if preferred).
- Whip for 10–15 minutes. The mixture will transform from translucent to thick, white, and glossy, and will hold soft peaks when you drag a spoon through it. The foam should be stable but still slightly delicate—overmixing can make it grainy, undermixing too loose.
- If desired, add a few drops of food coloring during the last minute of whipping for colorful marshmallows.
Shape and Set
- Quickly scrape the whipped marshmallow mixture into your prepared, powdered-sugar-coated pan. Smooth the top with a spatula or the back of a spoon.
- Let the marshmallows set at room temperature, uncovered, for at least 4 hours (overnight is even better for easy cutting).
Cutting and Storing
- Once set, sift more powdered sugar over the top of the marshmallows.
- Run a knife around the edges to loosen, then use a spatula to help lift the slab out of the pan.
- Cut the slab into 8 strips, then cut each strip into 8 pieces for classic squares (or your preferred size).
- Toss the cut marshmallows in powdered sugar to coat all sides, preventing sticking.
- Store in a covered container at room temperature. Homemade marshmallows are best enjoyed within 3–4 days, though they can last up to a week if kept dry.
Tips for Perfect Marshmallows
- Temperature is key: Always use a candy thermometer to monitor syrup closely. If it goes above 240°F, it moves into hard-ball stage and won’t work for marshmallows .
- Don’t rush the cooling: Let the syrup cool for a couple of minutes before adding it to the gelatin to avoid “cooking” the gelatin and ending up with a grainy texture.
- Customize flavors: Add peppermint extract, cocoa powder, citrus zest, or other flavors with the vanilla for unique variations.
- Add-ins: Stir in mini chocolate chips, crushed peppermint, or toasted coconut just before pouring into the pan.
- For larger batches: Double the recipe and use a 9×13 pan for thinner, bite-sized marshmallows—perfect for gifts or parties.
Troubleshooting Common Issues
Even experienced cooks can run into marshmallow-making mishaps. Here are solutions to common problems:
- Marshmallows are too sticky: You may have skipped dusting with enough powdered sugar, or the marshmallows didn’t set long enough. Coat all sides thoroughly with powdered sugar and give them extra time to dry.
- Marshmallows are dense or tough: The syrup may have been overheated, or the gelatin not bloomed properly. Ensure accurate temperature and proper gelatin preparation.
- Grainy texture: Hot syrup added too quickly to gelatin, or not whipped long enough. Add syrup gradually and whip until thick and glossy.
- Marshmallows won’t set: The humidity may be too high, or the mixture wasn’t whipped enough. Try making on a dry day and whip until stiff peaks form.
Why This Recipe Works (No Corn Syrup Needed!)
Traditional marshmallow recipes often rely on corn syrup to prevent sugar crystallization and create a smooth texture. This recipe achieves the same result using classic candy-making techniques—heating sugar syrup to the precise soft-ball stage and whipping it with gelatin. The key is temperature control and gradual mixing, resulting in marshmallows that are every bit as fluffy and tender as those made with corn syrup.
Frequently Asked Questions (FAQs)
Q: Can I use a hand mixer instead of a stand mixer?
A: A stand mixer is highly recommended because of the long whipping time, but a powerful handheld mixer can work in a pinch. Just be prepared for some arm fatigue!
Q: How can I make flavored marshmallows?
A: Add extracts (peppermint, almond, citrus), spices, or swirls of melted chocolate, Nutella, or fruit purée during the final stages of whipping to customize your marshmallows .
Q: Can I cut shapes instead of squares?
A: Absolutely! Use cookie cutters to cut out fun shapes. Dust them with powdered sugar and enjoy. For best results, dip the cutter in powdered sugar between uses.
Q: How long do homemade marshmallows last?
A: Stored properly, homemade marshmallows keep for 3–4 days, and up to a week in dry conditions. They can dry out over time, so enjoy them fresh for best texture.
Q: Why are my marshmallows sticky?
A: Stickiness can occur if not enough powdered sugar was used when shaping or storing, or if the humidity was high when making them. Increase the dusting and try to make on a dry day.
Q: Can I make marshmallows without gelatin?
A: Traditional marshmallows require gelatin. However, you can use agar agar for a vegetarian version, though the texture will be different.
Q: Can I use honey or maple syrup instead of sugar?
A: Substituting honey or maple syrup will alter both the flavor and texture, and may affect the set. For classic marshmallows, stick with white sugar.
Creative Variations
- Chocolate Swirl: Melt some chocolate and drizzle it over the marshmallow slab before it sets, then swirl with a knife.
- Nutella Marshmallows: Warm Nutella and gently fold it into the marshmallow mixture at the end of whipping for a hazelnut-chocolate twist .
