Begin by preheating the oven to 200C (390F). Transfer 100g of the oatmeal to a blender and blend into a fine flour.
Mash all but 1 off the bananas in a bowl, then combine with the vanilla extract, maple syrup and milk.
Next add the oat flour, remaining oats, baking powder and protein powder and combine. Fold through ¾ of the blueberries.
Transfer the mixture into 12 cupcake cake liners in a cupcake tin then top with the remaining blueberries. Slice the last banana and add the slices to the top of the muffins. Bake in the oven for 25 minutes.
