Preheat oven to 400F (200C).
In a large bowl mash the potatoes using a potato masher or grate using the small holes of the grater.
Add green onion, garlic powder, chili flakes, salt and pepper. Stir to combine.
In another bowl combine panko bread crumbs with smoked paprika and oil, until oil is absorbed.
Dust your hands with flour, take about a spoon of potato mixture, flatten and add a cheese cube in the center. Wrap and form into a ball. Roll in flour, dip in egg and then roll in panko mixture, pressing if necessary to stick well. Repeat with the remaining potato mixture.
Place the ball into a parchment paper lined baking sheet.
Bake for 15-18 minutes until golden and crisp. Don’t overbake or the cheese will start to seep out.
Cool for a few minutes before serving.
