Homemade Marshmallow Creme is so much more delicious than store bought, and easier to make than you think! Use it in meringues, frostings, as a filling, or any type of s'more dessert!
Place the egg whites and cream of tartar in the bowl of a stand mixer fitted with the wire whip attachment and whisk gently to combine. Set aside.
Place the granulated sugar, corn syrup, water, and pinch of salt in a small saucepan fitted with a candy thermometer over medium high heat and stir with a wooden spoon until combined.
Heat the mixture until it comes to softball stage, or 240 degrees, and immediately remove from heat.
When the mixture is almost to softball stage, begin whipping the egg whites and cream of tartar just until they have soft peaks. Turn the mixer down to the lowest setting and add the hot syrup down the back of the mixing bowl away from the wire whip in a slow, steady stream. Be careful not to add too much at once or the egg whites will cook.
Once all of the syrup has been added, whip on medium high speed for 6-7 minutes, or until the creme has stiff, glossy peaks and has cooled considerably. Add the vanilla extract and beat 2 minutes more.
Store in the refrigerator in an airtight container for up to 2 weeks. Enjoy!
