For my daughter's "Frozen" birthday party, we made Olaf snowman doughnuts.
You need a package of the small powdered doughnuts (we used hostess brand), powdered doughnut holes, mini chocolate chips, pretzel sticks, and toothpicks.
Stack 2 small doughnuts on top of eachother, put in a toothpick so the point is sticking straight up. Then carefully stick a small doughnut hole on top. (The toothpick helps stabilize the snowmen. Without it, the head keeps rolling off if the plate is bumped.) Stick mini chocolate chips in as eyes and buttons. Snap mini pretzel sticks in half and poke in as the arms and nose. These were a huge hit with the kids! Just be sure to take out the toothpick if serving to small children.
