These are so colorful and festive looking it makes you feel like it's a party when you look at an assortment of them. And they couldn't be easier to make, even your kids could do it. You can use white chocolate too, for a more wintry or icy look.
Line a sheet pan with waxed paper. Cut 1-inch off the end of each banana. Insert a popsicle stick into the cut-end of each banana, pushing the stick halfway in, leaving the other end exposed for use as a handle. Place the bananas on the sheet pan and freeze 1 hour.
Melt the chocolate and butter in a bowl over a saucepan of simmering water, stirring occasionally.
Arrange the dipping decorations on several flat plates. Working with 1 banana at a time, dip it in the chocolate and turn to completely coat (spoon some on, if needed). Roll the dipped banana in the desired decorations, transfer to the sheet pan, and return to the freezer.
Once frozen, store the bananas in an airtight container.
Serving suggestion: To serve at a kid's party, paint a hunk of styrofoam and stick the banana handles in the top, so they stand upright.
