I did tell them before they ate it, I was handing over the plate to him as I told him what was in it. I would never give someone food without them knowing what was in it in case they were allergic; he just over reacted. I've never done drugs or was an issue child in the past so I'm not sure why he thought I put something else in them! Needless to say they loved the brownies once I convinced them it was just cinnamon.
