A chef I am not!

So today we are doing a pasta potluck for those of us teachers who have 2nd lunch. I signed up to bring brownies. I just seemed to have troubles at every turn. First, I didn't have a pan to bake them in because it just wasn't something I thought to buy when moving in to my new apartment. So a quick trip to the local Target fixed that problem. Second, when I was getting the measuring cups out for the water and oil, I could not find the 1/3 cup . I have 1/4 cup, 1/2, 3/4 cup and 1 whole cup, but no 1/3. I looked in all the cupboards and drawers, I looked in the dishwasher, but to no avail it did not exist. So then I had to sit there and try to figure out the math. 1/3 is more than 1/4 but less than 1/2, so I could use the 1/2 cup but not fill it up all the way, or the 1/4 cup and then add some extra. I did the second of the two and added what I hoped was 1/3 cup water. Water!?! oops!! It was supposed to be 1/3 cup oil and only 3 tablespoons of water. In all my frustration and discombobulation I had hastily mixed the two up. So now I had to pour out some of the water, which had now turned a muddy brown color, trying to only allow 3 tablespoons remain. Of course some of the powder snuck out too but this was not too easy a think to accomplish. Then I had to estimate 1/3 cup oil to add and an egg. Stir it, pour it and shove it in the oven. 32 minutes later I pull them out and they look suprisingly decent. I didn't eat one because I needed everybit to take for the potluck, but I did lick the spatula and eat the crumbs that come off as you are cutting them. Those seemed all right, nothing terribly wrong. so I hope all is well .
