Pre-heat the oven to 200°C. Grease a 12-hole cupcake tin with the butter. Prepare the fillings as described above.
Whisk the eggs, milk, salt and pepper together. In a small pan, cook the mushrooms for about 3 minutes until browned.
Distribute the 3 fillings across the tin (there should be 4 of each flavour). Fill the holes with the egg mixture and then sprinkle the corresponding cheese over the mix. Bake for 20-25 minutes until cooked through. Serve warm.
