How to store leftovers
These birthday brownies can be stored at room temperature in an airtight container for up to 3 days. In the refrigerator for 1 week.
They do freeze well, but I recommend not frosting the brownies and freeze them before. Then when you need to take them out, frost them then.
Mel's kitchen notes
Do not overmix your brownie batter or you'll end up adding air to it. This will then cause it to rise a little - but then it'll sink in the middle.
Dress up your birthday brownies in the most festive way appropriate for whoever you are making them for. Serve with ice cream too.
