How to make brownies and which brand is the best?

im a 13 yr old boy and i love cooking. betty crocker are the best. dark chocolate and fudge are the best. follow the instructions on the back of the box... spray it with non-stick, mix it until it doesn't have chinks. im not hardworking. and im not a mother. i usually use a 8x8 dish. makes the tallest brownies. and fluffiest. i hate frosting on brownies, but dont microwave it. the brwnies warm it up enough to make it spreadable and tasty.
