Place all ingredients, except the sprinkles, in a bowl or blender and stir or blend until combined.
Fold in the sprinkles and pour immediately into popsicle molds. Insert popsicle sticks and place in freezer. (To prevent popsicle sticks from floating up, soak in warm water for 30 minutes before using).
Freeze for at least six hours, or until completely frozen.
Remove form freezer and place popsicle molds under warm running water for a few seconds, to allow the popsicles to easily slide out.
Store left-over popsicles in a sealed freezer bag or air-tight container for up to a week.
