Place oats, buckwheat, cinnamon, baking powder and salt into the Thermomix bowl and mill 10 sec/speed 10.
Add remaining pancake ingredients except pecans and blend 20 sec/speed 6. Stir through the pecans by hand. Allow mixture to sit in the Thermomix bowl for ten minutes while you prepare toppings.
Preheat a flat frying pan to a medium heat for at least 5 minutes.
Brush with a little oil and fry pancakes one at a time, turning very carefully. They are quite delicate until flipped, so be careful. Add more oil as needed and cook them all.
Serve stacked with all the fillings, to keep them dairy free use the coconut cream, but you could also use sour cream, or Greek yoghurt to dress them as well.
