Whisk milk, eggs and flour together in a large bowl until smooth and combined.
Add corn, zucchini, cheese, spring/green onions, dried herbs, garlic powder and salt and pepper. Stir until well combined.
Heat a little oil in a large non-stick frying pan over medium heat until hot. Spoon 4 x 1/4 cup measurements into pan and cook for 3-4 minutes each side or until golden brown and cooked through. Transfer to a wire rack and repeat with remaining mixture to make 12 fritters.
Serve immediately or allow to cool slightly and serve warm or cold.
