It's been such a long time, but I think it was either cinnamon rolls or peanut butter cookies.
The cinnamon rolls turned out great, in fact I got on a kick with making them regularly. I saw a recipe on the back of a Bisquick box and wanted to give it a try. I was pretty impressed with how they came out and how close they were to the stuff I could get at the store. This was right around the time when our mall got it's first Ciinnabon, so I was eating those a lot prior.
My first attempt at peanut butter cookies was a disaster however. I'm still not quite sure what I did wrong - I either mixed up my measurements or added them in the wrong order, because all the cookies turned into 1/8" thick flat pancakes and all bled together. There was nothing salvageable from them.
