This Giant Birthday Cookie is soft and chewy inside with crisp edges. It's loaded with chocolate chips and rainbow sprinkles. Best yet, it's gluten free, nut free, eggless and easily vegan!
In a small bowl, using a spoon, mix together the cornstarch and water until thin and watery. It will be thick and tacky at first.
You're only going to use ONE tablespoon of this mixture.
In the large bowl of an electric mixer or using a hand held mixer, beat the softened butter or vegan baking stick and the dark brown sugar until soft and creamy.
About 2-3 minutes.
Beat in only ONE tablespoon of the cornstarch water (discard the rest), the milk and the vanilla until fully combined. It will appear chunky. That’s normal.
