Easiest recipe ever. Kinda white trash, I’m not gonna lie. But delicious, delicious white trash. This is one of those recipes that seems to have been in my family since the dawn of time, but no one really knows where it came from. Why are they called Church Windows? Once sliced, you have a cross-cut of multi-colored spaces in a dark chocolate “frame” – they look like stained glass windows. It's another confection that adds a little pop of color to a cookie tray that will otherwise mostly be shades of brown.
