Get your kids in the Halloween spirit with this delicious and healthy shake! If blueberries aren't a favorite in your house, swap them with an equal amount of strawberries, raspberries, or blackberries instead. If serving these for a party, consider handing them out in paper cups and let the kids draw scary faces while they're waiting to be served.
1/2 tsp. cinnamon
