- 1 cup light corn syrup (ensures smooth texture)
- ¼ teaspoon salt (enhances flavor)
- 1 teaspoon vanilla extract (adds depth)
- 1 teaspoon cotton candy flavoring (or cotton candy syrup for extra sweetness)
- Powdered sugar, for dusting (prevents sticking)

Pro Tip: This recipe takes 30% less active time than traditional marshmallow recipes, with most time dedicated to setting.
Step-by-Step Instructions
Step 1: Prepare Gelatin
In a small bowl, sprinkle gelatin over ½ cup cold water and let it bloom for 10 minutes. It will transform into a spongy, gel-like consistency.
Step 2: Make Sugar Syrup
In a medium saucepan, combine granulated sugar, corn syrup, salt, and remaining ½ cup water. Heat over medium until sugar dissolves, then bring to a boil. Using a candy thermometer, heat to 240°F (115°C) – the soft-ball stage.
Step 3: Combine Gelatin and Syrup
Remove syrup from heat and carefully pour it into the bloomed gelatin while mixing on low speed with a stand mixer. Safety Tip: The mixture will be extremely hot, so pour slowly and carefully.
Step 4: Whip to Perfection
Increase speed to high and whip for 8-10 minutes until the mixture is thick, fluffy, and slightly cooled. Add vanilla extract and cotton candy flavoring during the last minute of whipping. The marshmallow should form stiff peaks.
Step 5: Set Marshmallows
Lightly grease a 9×13-inch pan and dust with powdered sugar. Pour the marshmallow mixture into the pan and smooth the top. Let set at room temperature for 4 hours or overnight.
Step 6: Cut and Coat
Dust a knife with powdered sugar. Cut marshmallows into squares and coat each piece with additional powdered sugar to prevent sticking.

A: Add a few drops of food coloring during the last minute of whipping, or use natural alternatives like beet powder or butterfly pea tea.
Q: Can I make these without a stand mixer?
A: While possible with a hand mixer, the high volume requires significant mixing time and may not achieve the same level of fluffiness.
Q: Why are my marshmallows too sticky?
A: This usually means the sugar syrup didn’t reach the correct temperature or the marshmallows need more setting time.
Q: Can I use this recipe for rice krispie treats?
