Peel and grate the sweet potatoes and carrots. Mix with the oat flakes, flour, potato flour and the egg. Salt and pepper the dough generously and stir well again.
Heat some olive oil well in a non-stick pan and use it to form small potato pancakes from a heaped tablespoon of batter. When the edge turns light brown, carefully turn the potato pancakes and finish baking over medium heat.
Drain the fried potato pancakes on kitchen paper or place them next to each other on a baking sheet lined with crispy-and-fry paper. I always use the paper because the potato pancakes can be kept warm in the oven or reheated.
It goes best with fresh salad and / or sour cream sauce.
