Place 6 foil cupcake liners in muffin pan. Place white chocolate chips in a bowl and microwave for 1 minute on medium heat. Stir to melt. If needed, microwave in 10-second intervals on medium heat until fully melted.
Using the back of a spoon, spread chocolate across bottom of foil cup, then spread the chocolate up the cup's side. Repeat to make 6 cups. Refrigerate until set, about 10 minutes.
Peel foil from chilled cups. Place a scoop of frozen yogurt in each cup, and top with a cherry. Once assembled, keep frozen for up to 3 hours.
If you don't have white chocolate chips, regular ones are tasty too.
