Preheat oven to 165°c. Prepare and grease muffin tray. (We use oil spray)
Sift the flour and baking powder into a large mixing bowl, then add the sugar and mix well.
In a separate bowl whisk together the wet ingredients.
Add the wet ingredients into the dry ingredient large mixing bowl. Then add the blueberries and cinnamon.
Use your hand to mix the ingredients together, but do not over mix. Aim for 3 stirs with your hand but no more then 5!
Trust us! It wont be perfectly mixed together so it will be very tempting to mix more but stop yourself. The ingredients will blend together as they cook.
Scoop the mixture into the 12 cases, filling them to the top. Sprinkle each muffin some oats.
Bake in the oven for 30-34 mins, depending on your oven and size of muffin tin, your cooking time will vary slightly. So keep an eye on them at the end, if an inserted skewer comes out clean you know they are ready.
Allow to cool for 5 minutes then remove from tray and place on cooling rack (cooling them in the tray would create damp bottom and sides).
Enjoy!
