In a medium saucepan, combine the corn syrup, sugar, water, and vanilla over medium-high heat.
1 cup light corn syrup, ½ cup granulated sugar, ¼ cup water, 1 teaspoon vanilla extract
Stir occasionally and cook until the mixture reaches 240°F on a candy thermometer.
While the syrup cooks, use a stand mixer fitted with the whisk attachment to whisk the egg whites and gelatin until frothy.
3 large egg whites, 0.25 ounce unflavored gelatin
Once the syrup reaches 240°F, remove it from the heat. Turn the mixer to low and slowly drizzle the hot syrup into the egg white and gelatin mixture.
Increase the speed to high and whisk until the mixture becomes thick, glossy, and holds its shape, about 8 to 10 minutes.
Serve with fruit, crackers, pancakes, waffles, hot chocolate, or desserts.
Notes
The whole recipe makes approximately 2 cups.
This homemade marshmallow fluff is best used as a dip or topping. It is not the same texture as store-bought marshmallow creme and should not be used as a 1:1 swap in recipes like fudge.
Store in an airtight container in the refrigerator for 3 to 4 days.
The calories listed are an approximation based on the ingredients in the recipe card and a serving size of about 2 tablespoons. Actual calories will vary.
