Annabel de Vetten - the 41-year-old creator - has been inundated with orders for the chocolate. One life-sized head weighs one kilogram and contains 5,000 calories.
"The global phenomena which are the Conjurer's Kitchen hand-painted solid white chocolate zombie baby heads are both amazing and disturbing," said the description on Etsy.
"Delicious to eat, or can be kept and displayed as a sculptural piece."
de Vetten said: "The look is quite controversial but if everybody liked them they wouldn't be as fun to make... I don't actually like chocolate that much, and there had to be a lot of experimenting."
Each head costs £35.
