One possible source of the recipe for Mantecadas de Astorga is Juan de la Mata, "confectioner to the Court, hailing from Matalavilla, in the municipality of Sil de Arriba, Montañas and the Kingdom of Leon and the diocese of Oviedo", whose book "Arte de Repostería" (The Art of Confectionery), published in Madrid in 1747 by Antonio Martín, contains the recipe.
