I just found a great blog post (here) with a list of gluten free Easter candy.
Cadbury items this year are NOT gluten free!!. I'm sorry for any confusion; in the past they have been gluten free. This year, Cadbury used a wheat-derived glucose syrup and thus they are not gluten free. I'd also like to add that my personal favorite, Starburst Jelly Beans, are also gluten free!
Enjoy! And Happy Passover/Easter! Which reminds me, I need to order my Sprinkles flourless chocolate cupcakes before it is too late!
UPDATE: This year, Cadbury is testing a new formula that uses glucose syrup derived from wheat thus making their eggs NOT gluten free. Please see THIS article for details.
