Combine potato, cheese, corn and egg in a bowl. Mix well to combine. Divide mixture into eight portions and form into small cakes.
Heat a non-stick frypan over medium heat. Melt butter and cook cakes, 4 at a time, for 5 minutes each side or until golden and crisp.
Serve as a snack after school or as a vegetable dish with the main meal.
No greens in sight for kids, but you could add peas, parsley or other mashed veg to these tasty little cakes.
