Cake Baked in a Hat
Cake Baked in a Hat is a comedy routine in which the magician cracks eggs and pours them and the other ingredients for making a cake into a hat, usually borrowed, and then produces a real cake. The hat is shown to be unharmed.
This was a popular effect among magicians as early as 1749. A French magician, Delisle, magically cooked an omelette in a hat. Hyman Saunders produced pancakes during his tour of Jamaica in 1775.
