I have a odd attachment to this set of lime green bake ware from Pyrex. This lovely lime green square 8x8 Pyrex pan, is my favorite one for brownies.
The thing about the vintage Pyrex for me... is that I know how it will perform in the oven. No guess work. Preheat the oven to 350. Cook for 23 minutes. And I get a perfect set of brownies each time.
And of course, I always bake them from scratch. That is if a package of Betty Crocker brownie mix and my favorite can of Baker's Joy counts as, from scratch. :)
