The first Twix I ever had was from a train station vending machine in Germany and I was smitten. But while the US version is delicious, it’s not the same.
These Belgian cookies, especially the chocolate covered ones, have that same ‘je ne sais quoi’ I remember.
(I know these are wheat-based — it’s been years since I’ve actually had any, but they’re too good to discourage others from eating and I haven’t yet done a very thorough check of the new TJ’s gluten free cookie options)
