Line a 9"x13" pan with saran wrap and lightly oil it.

Since I'm obsessed with my Kitchenaid mixer, I used the bowl from it and added the 1/2 cup cold water then sprinkled the 3 packages of gelatin over the water. I let it sit for about 10 minutes. (You can also use a hand mixer for the entire process of marshmallows.)

While the gelatin and water are sitting, Combine the sugar, corn syrup and 1/4 cup water in a small saucepan on the stove and let the mixture come to a rapid boil.

Once it's boiling really hard, let it boil for about 1 minute.

Pour the boiling mixture into the soaked gelatin, be careful, it's really hot! Then turn on the mixer, using a whisk attachment, to high speed.

Add the salt and whisk for 12 minutes, or until the mixture is a thick marshmallow cream consistency.

Add in the vanilla and whisk to incorporate.

Pour the marshmallow mix into your prepared pan and spread evenly.

Take another piece of lightly oiled saran wrap and press lightly over the marshmallow, creating a seal.

Let the mixture sit for a few hours; until it's cooled and firmly set.

On a plate, combine equal parts icing sugar and corn starch.

Remove the marshmallow from the pan and cut into desired size (I cut mine into 1" squares) using scissors. Scissors really work the best for this!

Dredge each piece of marshmallow into the icing sugar mixture.

Store in an airtight container. Can also be placed in the freezer.
