Chop the Christmas tree cakes into pieces abou ½ inch wide and add them to a large bowl.
Gently fold in the thawed Cool Whip and vanilla Extract.
Fold in the sprinkles, then transfer to a serving bowl and top with additional sprinkles if you like. Serve with cookies, graham crackers, or fresh fruit.
I don’t suggest making Christmas tree dip more than 1 day before you plan to serve it. The texture of the dip will change the longer it sits. Since this dessert is so fast to make, you can easily make it right before you plan to eat it.
