I'm an official tester and received the milk chocolate version through the post yesterday.
We all thought the packaging was quite sweet in the little egg box and with the little spoons. Daughter, aged 11, was very excited about trying them. But only two spoons for four eggs was already a problem as we tried one each (DD, DH and me), so needed three spoons really. Can't see the point of putting spoons in but then not putting enough in.
Don't know if it was intentional but the wrapping for the top part seemed to come off easier than the rest of the foil, which was handy for holding it without getting chocolatey fingers.
The filling was quite nice, not as sickly as creme eggs, but could be more moussey. My daughter thought it should be lighter but liked the taste. We then fantasised for a while over the different flavours you could have - chocolate mousse, strawberry mousse, mango, caramel ... My favourite easter egg of all time used to be the ones filled with caramel and marshmallow, made by the competitor I think, what a pity you can't get them anymore!
We thought the eggs were just the right size, the chocolate was just a bit soft and thin to hold once scooped.
We all ate the egg by biting off the top and then scooping out the filling. DD thought this was great fun, I probably couldn't be bothered with a spoon usually and would in future eat it like a creme egg, my husband said the same.
My DD enjoyed the egg and thought it quite novel, not a special treat really but she doesn't eat creme eggs usually as they are too sickly for her so the only time she gets easter eggs is actually on Easter Sunday and afterwards until they've all gone, so maybe a special treat in that respect.
I would recommend the Cadbury Egg N Spoon to friends as it's not as sickly as creme eggs and tastes great but would love to see different flavour fillings.
