I’m a Cadbury cream egg person myself, but honestly it’s always the filling that’s the best bit and the only part of the reproduction recipe you actually need.
It wasn’t until I started looking for recipes that I found out those cream eggs have a yellow spot inside to simulate yolk. I still haven’t bothered with that step (or the chocolate shell for that matter).
Bite off the small tip of the egg and scoop out all the cream filling with a finger. Maybe eat the chocolate after (I don’t like chocolate, so only maybe).
Probably the finger scooping bit caused it to sort of mix and not show up, but idrk.
