Note to self---don't substitute York Pieces for anything. Ever.
This was my first BWD experience---I've made a version of these brownies before, but in larger portion and slightly different ingredients. I'm going to have to say, I prefer the version I've used in the past---Dorie's version seems to be a little fudgier---I prefer brownies that are more cake-like. Also...ended up using the York Peppermint Pieces that William picked up from the store. Unfortunately, they have a candy coating (blue and white) which isn't visually appealing, and doesn't stand up to oven temperatures! Live and learn! Conveniently packaged for large handfuls of minty goodness, though!
Maybe these deserve a second chance---with patties. :)
