I never got around to posting this, but a few weeks ago, I took the Betty Crocker gluten-free plunge and made a yellow cake. I don’t own a proper cake pan (I don’t bake that often), so I used one of my Pyrex refrigerator dishes (which can go from oven to fridge). This is what happened. It wasn’t bad.

We tried the brownie mix a few weeks ago. It was better than I expected!
