Right Size Baking

Today, I decided to 'rescue' some over-ripe bananas before they were thrown away - the plan: bake banana loaf muffin things.  The kitchen, however, is the domain of the 'kitchen elf', so I found it challenging to find what I needed: I found the required ingredients but not a baking tin of the right size.  I look for glassware of the right size and shape - even large foil takeaway containers, but all to no avail.  So adapting a technique from mold making I packed a larger container with crumpled tin foil (I decided against paper) to create the desired size and shape as you can see:


The remainder of the mixture was used to make muffins and while sat here writing this up I am already onto my second.
The recipe I used was from BBC Good Food and shown below:

75g butter, softened
100g caster sugar
2 large eggs
3 medium ripe bananas
A few drops of vanilla extract
200g self-raising plain flour
2 tsp baking powder
2 tbsp of milk

Mix everything together for two minutes and bake for an hour or so, until golden brown.  Extract from oven and leave to cool. :)
