Yay! for you! I will be contacting you about your prize!
Thank you to all of you who participated.
The answer is: The flat cookie goes with the shiny pan and the plump cookie goes with the pampered chef medium bar pan (stone). I love, love, love my stone. I use it for making pizza, cookies, biscuits, breadsticks, etc. I got it about a year and a half ago and will grab this pan over the shiny pans every time. I've never officially tested the pans with the same recipe but I thought I'd try it out. Well, they taste the same, but the plump ones are fluffier and prettier.
Speaking of a great pan. I will be having a Pampered Chef Party this Thursday at 7 p.m. at my house. (I'm not a consultant, and I don't get paid for endorsing their products). If you can't make it, but would like to order, here is the website. Let me know if you'd like to order anything.
