Mix and knead everything together; Let the dough rise for 45 minutes. Shape into croissants (not too big, they will still open). Bake at 200 ° C for approx. 5-7 minutes (to test whether the dough is still sticky).
The croissants are ideal as a birthday breakfast, e.g. for kindergarten! If stored in a cool tupper, leftovers will keep them fresh for a few days.
Variation: a little less sugar depending on your taste.
