Preheat the oven to 200°C (gas mk 6, 400°F). Place the eggs, oil, sugars and milk in a large mixing bowl and quickly beat together.

In another bowl, thoroughly mix the flour, salt and baking powder.

Add the dry ingredient mix to the liquid, and roughly mix it in - it does not have to be absolutely smooth.

Stir in the blueberries.

Fill a muffin tray with paper muffin cases, and then fill each case to near the top with the muffin mixture. Bake the muffins for 25 minutes.

This recipe makes approximately 12 muffins.
