Step 5
Bake 15 to 20 minutes, or until golden brown and firm to the touch.
Step 6
Sift powdered sugar over cookies while warm, and then again before serving.
The history of Spanish shortbreads dates back to the 16th century, their first appearance having been in Andalusia, some say in Estepa, others in Antequera. The likely origin of polvorones is still disputed, even today.
