These homemade marshmallows without corn syrup are soft, fluffy, and so much better than store-bought. Lightly sweet with a touch of cozy vanilla, they’re perfect for hot cocoa, s’mores, or enjoying on their own. You'll never go back to bagged marshmallows after having these!
Prepare. Grease a 9"x13" baking dish with one tablespoon of butter and generously dust with powdered sugar.
1 tablespoon unsalted butter, powdered sugar for dusting
Mix the Water and Gelatin. In a small bowl, stir together 1/2 cup water and the gelatin. Set aside to bloom until thickened.
1/2 cup water, 2 1/2 tablespoons beef gelatin
Make the Syrup. In a heavy saucepan, whisk together 3/4 cup water, sugar, and salt. If any sugar sticks to the sides, scrape it back into the pot to prevent burning.
3/4 cup water, 2 cups granulated sugar, 1/4 teaspoon salt
Heat To 240°F. Attach a candy thermometer and heat the mixture to 240°F over medium heat, about 10 minutes, whisking occasionally. Around 220° F, mine usually stalls out a little, so I bump up the heat just a smidge.
Combine with the Gelatin. Carefully pour the hot sugar syrup into the bowl of a stand mixer. Add the bloomed gelatin. Be mindful of splashing. That sugar mixture is extremely hot!
Whip and Add Vanilla. Mix on low for 1 minute, then add vanilla. Gradually increase to high, starting on medium-low for 1 minute, then medium-high for 1 minute before going to high. Whip until the mixture is white, thick, fluffy, and glossy.

Pour into Dish. Pour the marshmallow mixture into the prepared dish and smooth it evenly with a silicone spatula.
Add Powdered Sugar and Chill. Generously and evenly sprinkle the top with more powdered sugar. Then, refrigerate for 2 hours.

Slice and Coat. When the marshmallow has set and completely cooled, use a buttered knife to cut them into squares (any size you desire). Toss the marshmallows with more powdered sugar to coat the sides.
Enjoy! Enjoy as is or in hot chocolate for a cozy treat.

Notes
I usually set and chill the marshmallows in a 9″x13″ dish. For thicker marshmallows, use a smaller, deeper pan.
Reaching 240°F is important because it ensures the marshmallows have the right consistency. If you don’t have a thermometer, use the soft ball test, where a drop of hot syrup in cold water forms a soft, squishy ball that flattens when pressed.
The syrup is extremely hot. Begin by whipping on low, then gradually increase the speed to avoid splashing hot syrup.
Cutting marshmallows can be a little tricky. Lightly grease or butter your knife for easier cutting.
It’s normal for beef gelatin to be slightly odorous when it blooms. But it will dissipate as you whip the marshmallow mixture.
Before whipping, it’s normal for the mixture to be a brownish hue. It will turn white as you mix it.
