🍴 Equipment Needed

👩‍🍳 How to Make Cotton Candy Marshmallows (Step-by-Step)

Step 1: Prepare the Pan

Line a 9×9-inch pan with parchment paper and lightly grease it with oil or cooking spray.

Step 2: Bloom the Gelatin

In the bowl of a stand mixer, sprinkle gelatin over ½ cup cold water.
Let it sit for 5–10 minutes to absorb the water (“bloom”).

Step 3: Cook the Sugar Syrup

In a saucepan, combine:

  • 2 cups granulated sugar

  • ½ cup corn syrup

  • ¼ cup water

  • ¼ tsp salt

Heat over medium-high and stir until the sugar dissolves.
Insert your candy thermometer and boil the mixture until it reaches 240°F (115°C).

Step 4: Whip the Marshmallow Mixture

Turn your mixer to low speed. Slowly pour the hot syrup into the bloomed gelatin.
Once combined, increase speed to high and beat for 10–12 minutes until thick and glossy.

Add:

  • 1 tsp cotton candy flavoring

  • A few drops of gel food coloring (pink or blue)

Mix just until fully incorporated.

Step 5: Transfer to Pan & Let Set

Pour the mixture into your prepared pan.
Smooth the top with a greased spatula.
Let the marshmallows set at room temperature for 6–8 hours, or overnight.

Step 6: Cut & Coat the Marshmallows

In a bowl, mix:

  • ½ cup powdered sugar

  • ¼ cup cornstarch

Dust your surface, remove the marshmallow slab, and cut into squares using a greased knife or cookie cutter.
Toss each piece in the sugar-starch mix to prevent sticking.

🎨 Tips for Success

  • Use a Candy Thermometer – Critical for perfect texture.

  • Fully Bloom Gelatin – Ensures a smooth, silky base.

  • Customize Colors – Swirl blue and pink for a cotton candy vibe.

  • Let Set Overnight – Patience brings the best texture.

  • Grease Tools – Marshmallows are sticky, so prep your utensils!

🎉 Serving Suggestions

  • Add to hot chocolate for a fun, melty twist.

  • Skewer and dip in chocolate or sprinkles for party treats.

  • Use as a cupcake or ice cream topper.

  • Include in carnival-themed snack mixes.

  • Wrap in clear bags or mini boxes for adorable edible gifts.

❄️ Storage Tips

Room Temperature:

  • Store in an airtight container in a cool, dry place for up to 2 weeks.

Freezer:

  • Freeze marshmallows in a single layer, then transfer to a bag.

  • Keeps for up to 2 months.

  • Let thaw at room temp for 5–10 minutes before serving.

👉 If they get sticky, just toss with more powdered sugar!

❓ Frequently Asked Questions

1. Can I make these without a candy thermometer?

Yes, but it’s tricky. Drop some syrup into cold water. If it forms a soft ball, it’s ready.

2. Can I use cotton candy syrup instead of flavoring?

Yes, but reduce corn syrup slightly as it may affect the texture.

3. Can I make these without corn syrup?

Yes! Honey or golden syrup are good substitutes, but may slightly change the texture.

4. How do I make multi-colored marshmallows?

Split the mixture into bowls after whipping. Add different food colorings, then swirl them together as you pour into the pan.
