a) If you over bake these brownies, they will be dry. When testing, look for moist crumbs NOT a clean toothpick inserted into the center. When you see moist crumbs, they're ready to remove from the oven.
b) If making in cup cake form, spritz the cup cake liners with cooking spray before filling for easy release. Bake for 22-25 minutes until a toothpick inserted into the center comes back with moist crumbs. Adjust the baking time according to your oven, if needed.
c) Large eggs may be used, the brownies will have a slightly different rise.
