I had forgotten that I had signed up to bring a sweet until late that night. I had NOTHING!!! Everything I wanted to make I was missing one small ingredient. I was determined not to go to the store. So I had tried making s'mores brownies. All I was missing was 2 tbsps of baking powder. Soooo I made them without it. I mean really how could such a tiny flavorless ingredient make a big difference.
