Quite awhile ago I wrote a post about the Baker's Chocolate One-Bowl Brownie Recipe and how fantastic it is.
The only problem I found with these brownies is that they fell apart if you tried to get them out of the pan while they were hot, and if you waited for them to cool, they stuck like iron to the bottom of the well-greased pan.
Then I had an aha! moment.
Parchment paper! I shaped a sheet of parchment paper as well as I could to the bottom of the pan and poured in the batter.
Success! The brownies don't stick at all.
And they're going fast!
