In our house we always seem to have either:

a) run completely out of bananas, or;

b) have a massive collection of super ripe bananas sitting in the fruit bowl that no-one wants to touch.

There’s never just a nice, happy in-between banana situation going on here.

    The Thermomix method doesn’t include adding the brown sugar. I had to add it at the end as i wasn’t concentrating and didn’t realise I had missed it until after i had poured the mixture into the tin. So back into the Thermo it went. I think it still turned out good. Smells delicious. Can’t wait for it to cool and to add the caramel icing.

      Oh my apologies!! That was my typo! All fixed now and I’ve added it into the Thermie recipe. It shouldn’t matter that you added it later – don’t stress! Enjoy! xx

    What size pans do you use.

    1. Lucy Mathieson says:

      Hi Tim, I use a 20cm X 20cm square cake tin. xx

    Hey! Just made it and realised I accidentally used self raising flour instead of plain flour! Should I throw it out?

    1. Lucy Mathieson says:

      Hi Kaya, no not at all! It will still be delicious (just more cakey than blondie-like!). xx
