Cadbury's have said that the mini egg recipe hasn't changed
Ingredients for mini eggs from cadbury website. Palm oil and vegetable oils feature quite highly on the list. More palm than shea as well.
They may say they haven’t changed the recipe, but if the recipe includes “vegetable fat” and they don’t specify proportions, it’s highly likely they’ve substituted in palm oil for shea butter. Still “vegetable fat” so the recipe technically hasn’t changed…
