To make the monster donut, whisk together the powdered sugar, heavy cream, vanilla, and a pinch of salt until smooth. Once smooth, dip the (tops only) donuts into the glaze and shake off the excess. (If there is too much the sprinkles will fall to the sides.) Immediately dip glazed donuts into a bowl filled with the sprinkles. Use edible gel to attach the eyes (put a little gel on the back of the eyes and attach). Give the donuts 20+ minutes for the glaze to set.
In addition to the monster, you can also make vampire, mummy and spider donuts. (See Note 1.)

Notes
Note 1:Instructions: The directions above are for the monster donuts. For the vampire, mummy and spider donut ideas, please view the instructions in the body of the post.Nutrition information is not provided. Donuts and toppings are hard to approximate. I think it's safe to say these aren't a diet treat!
