Yummo, one of my favourite snacks.

I use:
1 cup plain flour
1/2 cup s/r flour
1 cup brown sugar
1 tsp ground cinnamon
125g butter, melted & cooled
2 eggs whisked
3-4 bananas, mashed (depending on their size)

Mix all together, place in a greased/lined loaf tin & cook 40-50 mins at 180 degrees. Easy peasy!

Sometimes I add dried apple or chocolate chips for the extra treat
