Preheat the oven to 175C/350F
Line a muffin tray with liners and lightly grease.
Place the wet ingredients in a bowl and whisk to combine.
In a separate bowl whisk the dry ingredients together.
Add the dry ingredients to the wet and stir until combined (do not over stir).
Add the blueberries and gently fold them through the muffin mixture.
Evenly divide the muffin mixture between the greased muffin liners.
Bake for 30 minutes, or until cooked through.
Remove from the oven and allow the muffins to cool in the tin before serving.
Muffins can be stored in an airtight container for up to 3 days (place in the fridge if the weather is warm or humid).
