Homemade Marshmallow Fluff

Step 1

Place water, sugar, and corn syrup in a medium saucepan. Stir to combine.

Step 2

Insert a candy thermometer into the pot and heat over medium-high. Do not stir from this point on as crystals will form.

Step 3

Wipe down your mixer bowl, whisk, etc with lemon juice or vinegar to ensure they are completely grease free.*

Step 4

Place egg whites and cream of tartar in the bowl of a stand mixer.

Step 5

When the sugar syrup reaches about 225°F, start whipping the egg whites to soft peaks. Approx 3-4mins.

Step 6

When the whites are ready, the sugar syrup should be at 240°F. Remove from the heat, turn mixer to medium and very slowly and carefully pour the sugar syrup into the whites in a thin, steady stream.**

Step 7

Once all of the syrup is in, set mixer to medium/high and continue whipping. The whites will deflate at first, but they will thicken and fluff up.

Step 8

Continue to whip for 7-8 minutes, or until the mixture is thick and fluffy.

Step 9

Add in vanilla and whip until the fluff has cooled completely.

Step 10

Use right away as a frosting or filling or transfer into an airtight container and store for up to 2 weeks at room temperature.***
