I recently acquired a Ninja and I am loving it. The first night we got it, the kids insisted on milkshakes and we used it four times the first day.
4 scoops ice cream
2 scoops malted milk powder
1 cup milk
2 ice cubes
3 Winter Oreo with the red creme
Put it all in the Ninja and blend for a few second and you have a yummy treat. The red specs from the cream made it a pretty holiday beverage that you could dress up with a bow around the mug and a candy cane.
