Coarsely grate the Parmesan. Mix the flour with baking powder, salt and pepper. In a separate bowl whisk together the eggs, milk, buttermilk, olive oil and herb mix. Stir in the flour mixture until combined. Stir in 100g (approximately 3 1/2 ounces) of the Parmesan.
Pour the batter into a greased muffin tin and sprinkle with the remaining Parmesan. Bake in a preheated oven at 200°C (approximately 400°F) for 25-30 minutes.
