Triple cheese & onion muffins

Heat oven to 200C/180C fan/gas 6 and oil a 12-hole muffin tin. Whisk the oil, egg and buttermilk. In a mixing bowl, mix the flour, 1 tsp salt and mustard powder, then stir in the cheddar, spring onions, chives and half the Parmesan.

Use a large spoon to gently fold the wet ingredients into the dry – don’t overmix, just lightly combine. With the final few folds, mix in the soft cheese cubes. Spoon the mixture between the holes in the tin (they will be quite full), scatter with the remaining Parmesan and bake for 25 mins.
