Preheat the oven to around 50C Fan (this is just to keep the fritters warm).
Line a plate with kitchen towels and set out a non-stick baking tray.
Place the creamed sweetcorn and sweetcorn in a large mixing bowl. Add the plain flour, cornflower, baking powder and spring onion. Season well with salt and freshly ground black pepper.
In a large non-stick frying pan set over a medium heat, head 3-4 tbsp sunflower oil.
Once the oil is hot, add a heaped spoonful of the batter into the pan, using the tip of your spoon to create a nice, flat round shape. Repeat with another few heaped tablespoons, ensuring you leave enough space between them so they don’t stick together (I normally cook 4-6 at a time, the number you can cook at once will depend on the size of your pan). Cook the fitters for about 2-3 minutes on each side - or until golden brown and cooked through. Add more oil between batches, as necessary.
Once the fritters are cooked, carefully use your spatula (or palette knife) to remove them from the pan and place on the prepared baking sheet to allow the kitchen paper to absorb any excess oil. Place on the baking tray and pop in the oven to keep warm. Repeat with the remaining batter until you have about 12-14 fritters.
Serve with crispy bacon, smashed avocado, cherry tomatoes and a poached egg, if wished.
