Create soft, pillowy homemade marshmallows with a delicate vanilla flavor using sugar, corn syrup, gelatin, and vanilla extract. This medium-difficulty dessert yields 24 fluffy treats in about 4 hours including setting time. Essential tools include a stand mixer, candy thermometer, and 9x9-inch pan. Perfect for snacking, hot chocolate, or s'mores. Customize with food coloring or swap vanilla for peppermint and almond extracts.
The first time I made marshmallows from scratch, I stood there watching this weird liquid transform into white fluffy clouds, absolutely mesmerized. Store-bought marshmallows suddenly felt like they were from a different food group entirely. Now I cant go back to the bagged stuff after experiencing how incredible homemade ones taste.
Last winter my kids stood on chairs watching the mixer spin these puffy white peaks, their eyes getting bigger by the minute. We made peppermint ones and turned our kitchen into a sticky wonderland. Those marshmallows disappeared faster than anything Ive ever baked.
Ingredients
- 1 cup granulated sugar: The foundation of your syrup, reach for regular white sugar here
- 1 cup light corn syrup: This keeps your marshmallows soft and prevents graininess
- 1/4 cup water: Just enough to dissolve the sugar properly
- 1/8 tsp salt: Balances all that sweetness so it doesnt taste flat
- 3 envelopes unflavored gelatin: This is what creates the structure, dont skip or substitute
- 1/2 cup cold water: Cold water is crucial for proper blooming
- 2 tsp pure vanilla extract: Pure extract makes a noticeable difference here
- 1/2 cup confectioners sugar: For coating so they dont stick to everything
- 1/2 cup cornstarch: Mix this with powdered sugar for the perfect dusting coating
Instructions
- Prep your pan:
- Line a 9x9 inch pan with parchment paper and dust generously with half the confectioners sugar and cornstarch mixture, getting into all the corners.
- Bloom the gelatin:
- Combine gelatin with 1/2 cup cold water in your stand mixer bowl and let it sit for at least 10 minutes until it firms up into a solid mass.
- Make the syrup:
- Combine granulated sugar, corn syrup, water and salt in a saucepan, stirring gently over medium heat until sugar dissolves completely.
- Heat to temperature:
- Bring to a boil without stirring and cook until it reaches exactly 240°F on your candy thermometer, about 10 to 12 minutes.
- Combine hot and cold:
- With mixer on low speed, carefully pour the screaming hot syrup into the bloomed gelatin, then gradually increase speed to high.
- Whip it good:
- Whip on high speed for 8 to 10 minutes until the mixture is white, thick and has tripled in volume completely.
- Add flavor:
- Pour in vanilla extract and mix for another 30 seconds until fully incorporated.
- Spread quickly:
- Working fast before it sets, pour marshmallow mixture into your prepared pan and smooth the top with a damp spatula.
- Dust and rest:
- Sprinkle the top with remaining sugar and cornstarch mixture, then let sit uncovered at room temperature for at least 4 hours or preferably overnight.
- Cut and coat:
- Turn the slab onto a cutting board, cut into squares with a sharp knife dusted in powdered sugar, then toss all pieces in the coating mixture.
These became my go to holiday gift after watching peoples faces light up biting into something so unexpectedly luxurious. Theres something deeply satisfying about handing someone a bag of homemade marshmallows and watching them realize it's even possible to make them.
Flavor Variations
Swap vanilla for peppermint extract during winter months for the most incredible hot chocolate upgrade. Try almond extract for something nutty and sophisticated that pairs beautifully with chocolate desserts. A few drops of food coloring during the final whip turns these into something magical.
Storage Secrets
Homemade marshmallows last about a week in an airtight container at room temperature, though they rarely last that long in my house. Keep them away from humidity or theyll get sticky and sad. Layer them between wax paper if you need to stack them.
Serving Ideas
These shine in classic s'mores but try them melted into homemade rice crispy treats for next level results. Float them in coffee or hot cider instead of just hot chocolate. They also make the most playful addition to ice cream sundaes or chocolate fondues.
- Toast them carefully under the broiler for that campfire flavor indoors
- Dip them in melted chocolate for the easiest fancy dessert ever
- Cut them into shapes with cookie cutters before they fully set for special occasions
Once you make these, store-bought marshmallows will taste completely disappointing. Welcome to the rest of your life.
Recipe FAQs
- → How long does it take for marshmallows to set?
-
Allow marshmallows to set at room temperature for a minimum of 4 hours, though overnight is preferable for the best texture and easier cutting.
- → Can I make marshmallows without a stand mixer?
-
A stand mixer is highly recommended as the mixture needs to whip for 8-10 minutes on high speed to triple in volume. A hand mixer may work but requires significant effort and careful attention to avoid overheating the motor.
- → What temperature should the sugar syrup reach?
-
Heat the sugar syrup to exactly 240°F (115°C) using a candy thermometer. This temperature ensures proper marshmallow texture—too low and they'll be sticky, too high and they'll become hard.
- → How should I store homemade marshmallows?
-
Store cut marshmallows in an airtight container at room temperature for up to 1 week. Keep them dusted with the confectioners' sugar and cornstarch mixture to prevent sticking.
- → Can I use different flavors in this marshmallow recipe?
-
Replace the 2 teaspoons of vanilla extract with peppermint, almond, or other extracts. Add food coloring with the vanilla for vibrant colored treats that maintain the same fluffy texture.
- → Why do I need to let the gelatin bloom?
-
Blooming gelatin in cold water for 10 minutes softens and hydrates the powder, allowing it to properly dissolve and incorporate with the hot sugar syrup. Skipping this step results in grainy, uneven texture.
