Crunchy cookies from Penedes, Spain

I visited the Penedés region in Spain a couple years back and had these amazing, crunchy, nutty cookies (similar consistency to Italian biscotti but even more dense) and am on the hunt for their name and - hopefully - a recipe.

I first had them with a cup of coffee at a cafe and later found them in a specialty grocery store (bonArea in Sitges) but cannot see them in their online store.

I believe “Penedes” was in the name.

Any hints or clues to help me find them would be much appreciated - I can’t get them off my mind! 🤤
