I grew up on the West Coast with Little Brownie Bakers and LOVED their cookies. When I moved to the East Coast, I didn't understand why the cookies were different, but then learned about both bakeries. Over the years all recipes have changed, as people become more health conscious. Different sweeteners, different fats . . . changing ingredients does change the flavor of the end product.
In 2010, when I was working for our local Girl Scout Council (and they were considering changing bakers), I got to taste-test the "same" flavors, head-to-head: Carmel Delites vs. Samoas, etc, even Thin Mints vs. Thin Mints!
It was wonderful -- and I learned a lot:
no one makes the Thin Mints of my youth. (A chocolate cookie with a thin white layer of peppermint cream, dipped in chocolate far outshines both bakers' current version of chocolate cookie dipped in peppermint-flavored chocolate.) And I realized that, at least with the current recipes, I preferred ABC.
I've recently discovered that the best version of Carmel Delites/Samoas ISN'T sold by Girl Scouts at all, though -- it is at the grocery store: Coconut Dreams, made by those Keebler Elves!
So this year, I'll still buy Girl Scout cookies . . . but I will skip the Carmel Delites.
