Make billowy soft, slightly chewy, delicately sweet homemade marshmallows using just 6 ingredients. You can flavor them using vanilla or any candy oil you like.
Pour about 1/3rd of the powder blend through a fine-mesh sieve and sprinkle evenly over the bottom and sides of the pan.
Cover and save the remaining powder for later.
Pour about half of the remaining powdered sugar corn starch blend through a fine-mesh strainer, sprinkling it over the marshmallows.
Use your hand to press the marshmallows down into an even layer.
Set the marshmallows aside at room temperature for at least 4 hours.
Butter (or spray with baking spray) a long sharp knife and cut a 1 1/2 inch wide strip.
Wash the knife and grease it again then make another cut.
Cut 36 marshmallows are approximately 1 1/2 inches square.
Dip the sticky sides of the marshmallows in the remaining powdered sugar mixture.
Dust off any excess powder and your marshmallows are ready to serve.
