Banana Weet-Bix choc-chip muffins (improved)

Firstly, please don't correct my title spelling. This is the Australian version weetabix and I still call it weetabix and probably will for the rest of my life. Missing out the "a" in the middle seems strange.

So, Hanna wasn't very keen to help with making these, they sounded too healthy and not cakey and not sweet enough. You can tell how horrible they are. She has wolfed three of them today.

For anybody interested, here is the recipe. Suggestions for improvements in comments on taste website.
