Cake Batter Fro-Yo Cones

Ingredients:
sugar cones
1 package of funfetti cake mix
2 cups nonfat vanilla greek yogurt
2 cups cool whip
*optional mixins*-cookie bits, fruit, chopped candy bars, m&m's, reese's pieces, oreos, teddy grahams, etc. (the possibilities are endless  but keep in mind the pieces should be small enough to be piped through a ziplock bag)

Directions:
1.)  In a medium bowl, mix yogurt, cool whip and cake mix until fully combined. (fold in any mix ins here)
2.)  Place in a ziplock bag with the corner cut off and pipe into sugar cones (I like to set my cones in a coffee cup to keep them upright while I fill them)
3.)  Top with additional sprinkles and place upright in freezer until ready to serve.  (after an hour in the freezer, cones will be set and can be stored flat or wrapped in foil for later use)
