Preheat oven to 350°F and prepare your muffin tins with either liners or greasing each muffin cup.
Whisk the dry ingredients together in a medium sized bowl.
In a separate bowl, whisk the eggs and brown sugar together. Add the sunflower oil, milk and honey and mix well.
Mix the wet ingredients into the dry ingredients just until combined and no dry patches remain. Gently fold in the blueberries.
Divide the batter between the 12 muffin cups.
Bake for approximately 23 minutes or until the tops are browned and a tooth pick inserted comes out clean.
Cool on a wire rack before serving.
