Pinoy Spanish Bread

Pinoy Spanish Bread is actually a rolled pastry which looks like a croissant prior to being given a crescent shape, and has a filling consisting of sugar and butter. The bread is a pandesal rolled with filling.
When I was in Primary School, I and my classmates at Fast Learners'  Class would go to Hagonoy West Central School in Sto. Rosario every Wednesday to attend our advanced classes.  I would usually drop by this small bakery near Southern Institute (now Ramona S. Trillana) which sold yummy spanish breads.  They were I guess the best seller in that bakery or bakeshop.  I preferred to buy them than the usual pan de sal since I wouldn't have to worry about the "palaman" or filling since spanish bread has its own filling which makes it more yummy.  My Nanang Abe's small store would usually sell them too.  It's interesting that whenever we went to the town market to buy the stuff she sold in her store we would buy the spanish bread not from the bakeshop but from her "suki" where she got all the goodies she had at her store then.  They were wrap in 6s in a plastic bag.  Of course, they were not as good as the fresh ones from the bakeshop but still they were sold out at the end of the day.
