Ingredients You’ll Need
- 1/4 cup powdered sugar: This is used to coat the marshmallows and interrupt stickiness.
- 2 tablespoons cornstarch: Combined with the powdered sugar, it helps prevent the marshmallows from sticking together.
- 2 packets unflavored gelatin: This is essential for the marshmallow structure, giving them that wonderful fluff.
- 1 cup water, divided: We use half to bloom the gelatin and the other half in the sugar syrup.
- 3/4 cup granulated sugar: Adds sweetness and contributes to the marshmallow’s structure.
- 1/2 cup light corn syrup: This gives the marshmallows a smooth consistency and prevents crystallization.
- 1/4 teaspoon salt: Balances the sweetness and enhances flavor.
- 3 ounces strawberry jello: Introduces a fruity flavor and contributes color.
- 3 teaspoons strawberry extract: Enhances the strawberry flavor, making it rich and full.
- 2 drops red gel food coloring: Optional, for extra color to create that beautiful swirl.
How to Make Strawberry Swirl Marshmallows
Bloom the gelatin: In a small bowl, add the 2 packets of unflavored gelatin along with 1/2 cup of water. Let this mixture sit for about 5-10 minutes until it firms up, or “blooms.” This step is crucial for ensuring your marshmallows have the perfect texture.
Prepare the syrup: In a large saucepan, combine the 3/4 cup granulated sugar, 1/2 cup light corn syrup, the remaining 1/2 cup water, and 1/4 teaspoon salt. Set over medium heat, stirring occasionally until the mixture reaches a temperature of 240 degrees F. A candy thermometer will be helpful here – it’s the magic number for making perfect marshmallows!
Add the jello: Once the sugar syrup is hot enough, whisk in the 3 ounces of strawberry jello until fully dissolved. The vibrant color and luscious flavor will genuinely transform your marshmallows.
Mix in gelatin: Carefully pour the hot sugar mixture into the bowl with the bloomed gelatin. This will help it dissolve smoothly. It’s important to do this slowly and steadily to avoid splatters.
Whip it up: Using a stand mixer fitted with a whisk attachment, beat the mixture on high for 8 to 10 minutes. You’re looking for it to become fluffy, white, and hold stiff peaks. The transformation is quite mesmerizing!
Prepare the pan: While the marshmallow mixture is whipping, take an 8×8 inch square pan and lightly spray it with nonstick baking spray. In a separate small bowl, mix together the 1/4 cup powdered sugar and 2 tablespoons cornstarch, reserving half to sprinkle on top later. Dust the greased pan with the remaining powdered sugar/cornstarch mixture.
Add flavor and color: In the last minute of mixing, add the 3 teaspoons of strawberry extract and the 2 drops of red gel food coloring. This final touch will ramp up the flavor and aesthetics.
Transfer to the pan: Pour the whipped marshmallow mixture into your prepared pan, spreading it into an even layer. If you want to create a striking red swirl, add 1 to 2 more drops of food coloring on either end of the mixture, and gently swirl with a skewer for that artistic touch.
Dust and set: Sprinkle the top of the marshmallow layer with the reserved powdered sugar/cornstarch mixture to prevent stickiness. Now, let the marshmallows set at room temperature for at least 4 hours, although letting them sit overnight is best for full firmness.
Cut into pieces: Once firm, use a sharp knife or pizza cutter dusted with powdered sugar to cut the marshmallows into 12 equal pieces. If they stick, dust the knife with more of the sugar mixture for easy cutting.
Toss to finish: Finally, toss each piece of marshmallow in additional powdered sugar to coat all sides and keep the edges from becoming sticky.

Storing & Reheating
To keep your Strawberry Swirl Marshmallows fresh, store them in an airtight container at room temperature for up to two weeks. If you need to refrigerate them, place them in a covered container lined with parchment paper to prevent sticking; they’ll last about a month. You can even freeze these treats for up to three months! Just make sure to wrap them tightly in plastic wrap and then in a heavy-duty freezer bag. To refresh frozen marshmallows, let them thaw at room temperature for about 30 minutes.
Chef’s Helpful Tips
- Ensure your saucepan is clean for the sugar syrup—any tiny specks can cause crystallization.
- Use a candy thermometer to achieve the perfect temperature; it’s key to making soft marshmallows.
- Whipping the mixture too short won’t yield the required fluffiness, so let that mixer do its job.
- If your marshmallows seem a bit sticky, don’t hesitate to dust them liberally with powdered sugar after cutting.
- Experiment with flavors: vanilla, or raspberry extract can add a delightful twist if you’re feeling adventurous.
Strawberry Swirl Marshmallows bring a cheerful touch to your dessert table or special occasions. The fluffy, fruit-filled bites are whimsical and comforting, making them perfect for sharing with loved ones—or simply enjoying yourself. Don’t be shy; play around with the colors and flavors, creating your unique marshmallow masterpiece.
Recipe FAQs
Can I use fresh strawberries instead of jello?
While you can try using fresh strawberries, you’ll need to ensure they’re pureed and balanced with additional sugar since fresh fruit isn’t as sweet and lacks the firm consistency that jello adds. This may alter the texture of your marshmallows significantly.
How can I make these marshmallows without corn syrup?
You can substitute corn syrup with honey or agave syrup in a pinch, but keep in mind that it may affect the final consistency slightly. Make sure to adjust the sugar to maintain sweetness.
What should I do if my marshmallows aren’t fluffy?
If your marshmallows haven’t fluffed up, likely, they weren’t whipped long enough or the sugar syrup didn’t reach the required temperature. Next time, give it a little more time and make sure to use a thermometer.
Can I make these vegan-friendly?
Absolutely! You can substitute unflavored gelatin with agar-agar for a vegan version of your Strawberry Swirl Marshmallows. Adjust the blooming and setup instructions according to the package instructions for the best results!
