Mix baking powder, one of the dry vanillas, salt, and flour in a bowl and set aside.
Begin by making the butter soft with a mixer for at least 10 minutes. Add sugar and keep mixing for another 7 minutes. The secret to great kourabiedes lies in this step. This mixture must be white and very fluffy.
Add the egg yolks, one at a time.
Remove the mix from the mixer and slowly add half of the flour mixture and the raki, ouzo, or cognac.
Slowly add the rest of the flour carefully so as not to add too much at a time.
The mixture should not be hard but light and airy, so perhaps you might not need to add all the flour mixture.
Incorporate the almonds and once the mix has reached a firm consistency, shape them into small balls, or half-moon shapes, or any way you like!
You can even use cookie cutters to give the cookies a fun holiday-themed shape.
Place the cookies on a tray on top of waxed paper. Space them properly on the baking tray because they may double in size.
Bake at 170° for 20 to 25 minutes.
When you remove the kourabiedes from the oven, lightly sprinkle with rosewater (optional).
Let them cool and sprinke with the powdered sugar mixed with the remaining vanilla powder.
