Preheat the oven to around 160°F (70°C/50°C fan); this is just to keep the fritters warm.
Line a plate with paper towels and set out a non-stick baking sheet.
Place the creamed sweet corn and sweet corn in a large mixing bowl. Add the flour, cornstarch (cornflour), baking powder, and scallions. Season well with salt and freshly ground black pepper.
In a large non-stick frying pan set over a medium heat, add 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 fritters 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 to remove them from the pan and place on the prepared plate to allow the paper towels to absorb any excess oil. Place on the baking sheet 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 desired.
