Organic dark chocolate sauce or 2 3.5-oz dark chocolate bars(I like Ghiradelli Intense)
Fresh strawberries for garnish
4 hours prior to serving:
Place milk, yogurt, strawberries and bananas into Ninja blender (or other blender). Blend until smooth and place in an 8" square glass dish. Cover and place in freezer. Wait 2 hours then blend again. Repeat once more in another 2 hours just before serving.
To prepare bowls:
Pour some sprinkles onto a small flat plate. Set aside.
In a microwave proof measuring cup, place chocolate bars, broken up, and heat in 30-second increments until chocolate is almost melted. Stir until completely smooth. Pour half onto small flat plate.
Take waffle bowls, one at a time, and dip edges into melted chocolate then into sprinkles. Let sit until firm.
Remove yogurt from freezer and place in blender one last time. Blend until smooth. Scoop out into prepared waffle cones and drizzle remaining chocolate over top. Garnish with additional sprinkles if desired and a fresh strawberry.
Prep time includes 4 hours of freezer time. Actual prep is closer to 15 minutes.
