Homemade Marshmallow Fluff (also known as Marshmallow Creme) is easy to make at home for delicious nutter butter sandwiches, topping to cake, pies and cupcakes or to enjoy as a fruit dip.
Make sure all items you use are very clean and contain no oil or grease. You can wipe down your mixing bowl, spatula, whisk, saucepan and spoon with vinegar before using.
In a medium saucepan, place sugar, corn syrup, and water. Mix well. Heat over medium-high heat with a candy thermometer in the pan. Do not stir, just let the sugar mixture cook.
In a separate mixing bowl, beat egg whites and cream of tartar in a mixer until the peaks are firm, about 2-3 minutes.
When the sugar mixture has reached 240 degrees, remove the saucepan from the heat. NOTE: The sugar took about 10 minutes to come up to temperature, but all ranges will be a little different.
Turn on the mixer to low and slowly drizzle the sugar into the egg whites. When the pan is empty, turn the stand mixer to high and beat for about 4 minutes.
Scrape down the bowl and continue beating for another 4 minutes or until fluffy.
Add vanilla extract and beat until cool.
Use the marshmallow fluff right away or store it at room temperature in an airtight container for up to 2 weeks.
