4 c. yogurt (such as vanilla, coffee, or a combination)
mini chocolate chips (optional)
Divide the yogurt among eight 5-ounce paper cups. Sprinkle with chocolate chips, if using. Cover each cup with a piece of foil, sealing the edges. Make a small slit in the center of the foil and insert a wooden freezer pop stick. Freeze for at least 8 hours and up to 3 days. Before serving, discard the foil and tear away the cup.
