For the spider waffles, stir eggs, milk and flour to make a nice waffle batter. Put the waffle iron on and heat.
Take 1/8 l of the mixture and stir in a teaspoon of cocoa powder, pour into a small jug.
Paint a spider web on the waffle iron with the small jug of cocoa mixture, then pour a ladle of the light mixture in the center of the waffle iron.
Close the waffle iron and bake. Bake 8 or 9 waffles in this way, decorate with raisins as spiders and serve the spider waffles.
