i know for a fact that for your 1st question: when you put them in the oven the smell does seep out, u need to have the kitchen windows open and designate a 3-5 hour house-to-yourself period of time. also pick up a can of oxium non-scented air freshener for when the brownies are done and spray a bit around the kitchen, especially in front of the window.

i dont know the answer to your 2nd question sry :rasta:
