I tried a spanish sweet cake/biscuit beginning with the letter A today, but can't remember the full name?

It was something like Almendrados, but looking at the pictures I'm sure it's called something else, but it was quite a long name. I think it had almond or other nut inside. It was in a cardboard packaging, flat like a sleeve of chocolate and was a little crumbly to cut, but very rich and moist tasting.

If you know the name of this, it would be much appreciated.

Thanks
