Ingredients You’ll Need
- 1/4 cup powdered sugar: This is essential for dusting the marshmallows and preventing stickiness. You can substitute with cornstarch if you need a gluten-free option.
- 2 tablespoons cornstarch: Used alongside powdered sugar, it helps create a non-stick surface for your marshmallows.
- 2 packets of unflavored gelatin: This is the star ingredient that gives marshmallows their classic fluffy texture. Ensure you use unflavored, as flavored gelatin can alter the taste.
- 1 cup water, divided: We’ll use this to bloom the gelatin and later combine with sugar. Room temperature is ideal for blooming.
- 3/4 cup granulated sugar: Sweetness is key! Granulated sugar gives marshmallows their structure and helps them set properly.
- 1/2 cup light corn syrup: This keeps the marshmallows moist and adds sweetness without the need for additional granulated sugar.
- 1/4 teaspoon salt: Just a pinch enhances the overall flavor, balancing the sweetness.
- 3 ounces strawberry jello: This gives the marshmallows their vibrant color and fruity flavor. You can use other gel flavors if you like.
- 3 teaspoons strawberry extract: Real strawberry flavoring enhances the taste and aroma. Look for pure extract for the best results.
- 2 drops red gel food coloring: Optional, but it can intensify the pink color or create a fun swirling effect.
How to Make Strawberry Swirl Marshmallows
Bloom the Gelatin: In a small bowl, combine 2 packets of unflavored gelatin with 1/2 cup of water. Let it sit for about 5-10 minutes until it becomes gel-like and firm.
Prepare the Sugar Mixture: In a large saucepan, mix 3/4 cup granulated sugar, 1/2 cup light corn syrup, the remaining 1/2 cup of water, and 1/4 teaspoon salt. Place this over medium heat and stir gently until it reaches 240 degrees F on a candy thermometer.
Combine Gelatin and Sugar: Once the sugar mixture has reached the right temperature, remove it from heat and add the 3 ounces of strawberry jello, stirring until fully dissolved. The mixture should be smooth and glossy.
Mix in Gelatin: Pour the hot gelatin-sugar mixture slowly into the bloomed gelatin in your stand mixer bowl. This helps dissolve the gelatin and achieves the perfect texture when whipped.
Whip Until Fluffy: Use the whisk attachment to whip the mixture on high for about 8 to 10 minutes. It’s ready when it becomes fluffy, pale in color, and holds stiff peaks.
Prepare Your Pan: While your mixture is whipping, prepare an 8×8 inch square pan. Lightly spray the bottom and sides with nonstick baking spray.
Dust the Pan: In a small bowl, combine the remaining 1/4 cup powdered sugar with 2 tablespoons cornstarch. Dust the greased pan generously with this mixture to prevent sticking. Reserve the rest for later.
Add Flavor and Color: In the last minute of whipping, add 3 teaspoons of strawberry extract and 2 drops of red gel food coloring. Continue to whip until everything is combined.
Pour and Swirl: Carefully pour the marshmallow mixture into the prepared pan. If you want a red swirl, place an extra 1-2 drops of food coloring on either side of the mixture and use a skewer to gently swirl it around—I like a delicate marbled effect.
Dust & Set: Sprinkle the remaining powdered sugar/cornstarch mixture on top of the marshmallows, then spread it evenly. This helps to prevent the top from becoming sticky. Let the marshmallows rest at room temperature for at least 4 hours, but overnight is best to fully set.
Cut into Squares: Once they’ve set, use a sharp knife or pizza cutter (dusted with the sugar mixture) to cut the marshmallows into 12 pieces. Toss them lightly in the powdered sugar/cornstarch mixture to ensure they’re not sticky before serving.

Storing & Reheating
To keep your Strawberry Swirl Marshmallows fresh, store them at room temperature in an airtight container for up to two weeks. If you want to extend their life, pop the marshmallows in the refrigerator, where they’ll last for about a month. You can even freeze them for up to three months; just make sure they are well-wrapped to prevent freezer burn. When you’re ready to enjoy, let them come to room temperature as freezing can alter their texture a bit.
Chef’s Helpful Tips
- Avoid Stickiness: Make sure to dust your cutting tools with powdered sugar/cornstarch to avoid sticky situations when slicing.
- Temperature Matters: Using room temperature water for blooming the gelatin helps it dissolve better.
- Timing Is Key: Don’t rush the whipping stage; a slower mix helps capture air for fluffiness.
- Experiment with Flavors: Feel free to substitute strawberry for raspberry, blueberry, or even a combination of your favorites.
- Make Ahead: These can be made a few days in advance, perfect for parties!
Strawberry Swirl Marshmallows are a sweet, nostalgic treat that blend vibrant flavors with a fluffy texture. Plus, they make the perfect homemade gift or delicious addition to any event. I encourage you to play around with flavors and colors, making them entirely your own. Enjoy every fluffy bite and don’t forget to share some with friends—they’re sure to be a hit!
Recipe FAQs
Can I use different flavors of jello for this recipe?
Absolutely! While strawberry adds a lovely taste and color, you can swap it out for any flavored gelatin. Just remember that the jello flavor will significantly affect the final taste and color of your marshmallows.
Why did my marshmallows not set properly?
If your marshmallows are too soft, it may be because the sugar syrup didn’t reach the correct temperature. Be sure to check with a candy thermometer, as reaching 240 degrees F is crucial for achieving the right texture.
Can I make these marshmallows vegan?
Yes! To make these marshmallows vegan, substitute the gelatin with agar-agar, a plant-based alternative. You’ll need to adjust the liquid measurements slightly, as agar-agar requires different proportions.
How can I make these marshmallows more colorful?
Aside from the two drops of red gel food coloring, you can use natural food colorings for extra vibrancy. Swirling different colors will also make your marshmallows visually appealing!
