1. Line cupcake tins with the liners. Fill the tins two-thirds full with the batter and bake the cupcakes as directed on the box.
2. Frost the cupcakes. Pile the frosting up a little in the center to make a sort of domed shape, more like an eyeball. To make the surface smooth, dip a butter or frosting/palette knife in hot water and smooth it over the top of the frosting.
3. Using the red decorating gel, pipe the red frosting on the tops of the cupcake in vein patterns. Make the veins radiate from the center of the cupcake to make the bloodshot quality more realistic. Cut the jelly beans in half. Place a jelly bean half into the circle of the round candy. Now you have and iris and a pupil. Place this in the center of a cupcake. Continue with the rest of the eyeballs.
