Preheat an oven to 190C.
In the jug of the Vitamix Accent blender, combine the egg, banana, nut butter, honey, milk, oats, baking powder and blend to a smooth batter.
Pour this between your prepared cake tins or muffin moulds and top with the raspberries and chocolate.
Bake for approx. 20 minutes, depending on your oven, until a skewer or small knife comes out clean.
Allow to cool for 20 minutes then remove from the cake tin.
