The original recipe calls for an 8" or 9" baking dish. Today I made little individual cakes - perfect for entertaining (you can get custard cups/ramekins here). I also put some in a loaf pan to cut up into brownies. I'll freeze some for later enjoyment and give the brownies to my mom who is recovering from a hospital stay. She's diabetic, so these will be perfect for her. Know anyone who's diabetic and has a sweet tooth? Maria's book, Nutritious and Delicious, may be the answer.
This does freeze well. Make sure you cool thoroughly first and tightly wrap.
