Crush the Oreos and combine them with the melted butter. Divide them among 8 8 oz wide mouth mason jars. (Or press into a 9 inch deep dish pie pan.)
Whip together the cream cheese, whipped topping, vanilla, cake mix, and milk. I first used the paddle attachment and then the whisk attachment to make it nice and smooth.
Gently stir in the funfetti.
Divide equally between the mason jars. (Or fill your pie.)
Refrigerate four hours or overnight.
Top with whip cream, cherries, and more sprinkles.
