How to Make Salted Caramel Swirl Marshmallows
-
Prepare the Dish: Start by lining a 9×13-inch baking dish with parchment paper, allowing it to overhang on the sides. Lightly spray the parchment with nonstick cooking spray to prevent sticking.
-
Bloom the Gelatin: In the bowl of a stand mixer, pour in 1 cup of ice-cold water. Sprinkle the gelatin evenly over the water and whisk gently. Let it sit for 5 minutes to properly hydrate.
-
Combine Ingredients: In a large heavy-bottomed saucepan, combine the remaining cold water, sugar, and corn syrup. Cook over medium-high heat, stirring until the sugar dissolves before letting it boil until it reaches 252°F.
-
Cool the Syrup: Once it reaches 252°F, remove the pan from heat and allow the syrup to cool down to 212°F.
-
Mix with Gelatin: With the mixer on low speed, carefully pour the hot syrup into the bloomed gelatin. Mix on low for about 30 seconds, then increase to high and beat for 11–13 minutes until the mixture turns thick and glossy.
-
Add Flavor: Now, add the vanilla extract and give it another quick mix for about 10 seconds to fully incorporate the flavor.
-
Pour into Dish: Lightly spray a spatula with nonstick cooking spray, then pour the marshmallow mixture into the prepared pan. Use the spatula to smooth the top, creating an even layer.

Create the Swirls: Drizzle the warmed caramel sauce over the marshmallow mixture. Use a toothpick or a knife to create large swirls, taking care not to overmix.
-
Sprinkle Salt: Generously sprinkle flaky salt over the top, adding that delightful contrast to the sweetness.
-
Set the Marshmallows: Let your marshmallows sit uncovered at room temperature for at least 4 hours, or overnight, until they are fully set and firm.
-
Mix Coating: In a small bowl, combine the confectioners’ sugar with cornstarch. This will help coat the marshmallows and keep them from sticking.
-
Cut the Marshmallows: Dust a pizza cutter with the sugar-cornstarch mixture before cutting the set marshmallows into squares. Dredge each cut side in the mixture for an extra fluffy coating.

Store Properly: Place your marshmallows in an airtight container and store at room temperature for up to 3-5 days; they’ll remain soft and delicious!

Salted Caramel Swirl Marshmallows Recipe FAQs
How can I tell if my ingredients are fresh?
For optimal results, ensure your gelatin is within its expiration date and that your corn syrup and sugar are fresh and uncontaminated. Check for any signs of crystallization in your sugar or dark spots on gelatin. When selecting gelatin, look for a powdery texture; if it clumps, it might be old.
What’s the best way to store Salted Caramel Swirl Marshmallows?
Store your marshmallows in an airtight container at room temperature for 3-5 days. For longer freshness, you can refrigerate them, but consume within 7 days to avoid moisture issues. Always ensure they are well-coated with the sugar-cornstarch mixture to maintain their softness.
Can I freeze my Salted Caramel Swirl Marshmallows?
Absolutely! To freeze, wrap each marshmallow individually in plastic wrap, then place them in a freezer-safe container. They can be frozen for up to 2 months. When you’re ready to enjoy them, just let them thaw at room temperature for a deliciously soft treat!
What if my marshmallows didn’t set properly?
If your marshmallows remain sticky after the setting time, they may not have reached the proper temperature during syrup preparation. Ensure the syrup reaches 252°F before combining it with gelatin. If they are too soft, you can also try refrigerating for a firmer texture or pre-chilling your mixing tools to help with fluffiness.
Are there any dietary restrictions to consider with these marshmallows?
These Salted Caramel Swirl Marshmallows are made with standard ingredients and may contain allergens like corn (in corn syrup) and possible traces of gluten or dairy if using certain brands. If making for specific dietary needs, consider using a gluten-free corn syrup, or substitute the caramel sauce with a vegan version to accommodate different diets.
Can I use flavored extracts instead of vanilla?
Certainly! While vanilla adds a classic warmth, you can experiment with flavored extracts like almond or hazelnut for a fun twist. Just keep in mind that you’ll want to ensure any alternative flavor complements the caramel taste you’re aiming for in your marshmallows.
