Mash the bananas in a big bowl using a fork
In a separate bowl mix flour, oats, baking powder and dry seasonings
Add dry mix to banana, add raisins and mix
Add peanut butter and enough soy milk to loosen, shouldn't be too runny but also shouldn't be too thick
Fill 12 small cupcake cups (I use silicone), they should be fairly filled
Bake in the oven for around 15 - 20 minutes. The consistency of these will not be like usual cupcakes, less cake like, but they are delicious nonetheless and a cheap and cheerful sweet treat which is pretty good for you.
