Question for G & A Cake Centrum

Can you give me a good recipe for Spanish bread? For 3 months in 1986-87 I bought 6 pieces of it every day from a bakery there in San Fernando, fresh from the oven. It was the best. I tried a recipe with the filling made from butter and sugar. The filling oozed out of the roll dough and formed a hardball mixture for the dough to cook in. I appreciate any help from you.
