Choconana Muffins!

Today i had a very silly mummy moment.
It was baking time for lunchbox treats, and choconana muffins were the order of the day. The batter was mixed, the oven was on and the 9yr old was trying to help.
In went the muffins, and came out looking delicious! The washing up was started. All going well, i hear you say.
Until. I picked up a cup to clean which i realised still contained a. whole. egg. Which was supposed to be in the muffins! Oops.
They still taste nice though.
