Making Christmas Tree Brownies

I was making some brownies that look like Christmas trees on Sunday morning. Cora walked into the kitchen and asked 'Whatch-u-doin, Mommy?'. I told her what I was doing and she said 'I help you'. It was hard for me, but I pulled up a stool and let her do a tray of them. She loved it, so I am so happy I let her do it. She was proud of them too!
Then I looked up and saw her doing this! Oops...

Note the paper towel on the counter next to her tray to wipe her fingers on going forward.

Here's her tray of Christmas Tree Brownies.
