🛒 Ingredients

1 servings

1
  • 1 egg
  • 4 tablespoons milk
  • 3 tablespoons neutral oil
  • 3 level tablespoons self-raising flour
  • 1 tablespoon grated parmesan
  • 1 level teaspoon salt
  • Spices to taste (paprika, oregano, garlic powder)
  • 1½ tablespoons drained canned sardines (or tuna, shredded chicken, or vegetables)
  • 1 slice mozzarella, diced
  • 1 tablespoon canned corn and peas
  • Dried oregano to taste

Directions

  1. 1

    In a bowl, whisk the egg with a fork, then add the milk, oil, self-raising flour, parmesan and salt. Mix until the batter is smooth and lump-free.

  2. 2

    Prepare the filling: mash the drained sardines with a fork and combine with the diced mozzarella, corn, peas and dried oregano.

  3. 3

    Grease and lightly flour a large mug (at least 350 ml capacity) if you plan to unmould the cake.

  4. 4

    Pour half the batter into the mug, spoon the filling into the centre — don't go past the halfway mark — then top with the remaining batter. The total should not exceed ¾ of the mug.

  5. 5

    Microwave on full power for 3 to 4 minutes until the top feels firm to the touch. Rest for 1 minute before eating.

💡 Chef's Tip

No self-raising flour? Use plain flour plus ½ teaspoon baking powder. Switch the filling for whatever you have on hand — ham, roasted peppers, sautéed mushrooms, or leftover vegetables all work brilliantly.
