Tips For Making These Beautiful Bars

Make sure you use parchment paper to line your baking dish. Makes it much easier to pull out bars to cut into squares.

Use a plastic knife to cut your brownies into squares. No sticking, no mess!

Store any leftover brownies in an airtight container for 3 days on counter or 5 days in refrigerator.

These make great neighbor gifts too!
