Ingredients:
- 275 gr oat flakes
- 70 gr cane sugar
- 150 gr butter
- 1 egg
- Vanilla-sugar (either 1 vanilla-sugar bags; or I use cane sugar which has been resting with a Vanilla stick for few weeks)
Preparation (5 min):

Add all ingredients one by one, following the order here above. Make some hills on your bake plate (i take two teaspoons and press some dough between them).
UPDATE: I tried to replace 20 gr of cane sugar by 2 dates. It is excellent (but less crusty). I mix the sugar and the dates in the food processor, and add it to the rest.
Bake for min 15-20 min (until they are getting light brown) at 175°C.
