Preheat the oven to 180°C.
Grease and line a couple of baking trays with nonstick baking paper. Beat the caster sugar and butter together in a large mixing bowl until fluffy.
Sift the flour into a separate mixing bowl and stir in the Manchego and paprika. Combine the two mixtures until you have a dough, using your hands to bring them together. Divide the dough in two and roll the halves into 12 inch long sausage shapes on a lightly floured surface.
Cut each sausage into 12 discs and flatten a little into rounds. Arrange on the lined baking trays and stud with the diced chorizo and olive slices. Bake for 15-18 minutes until golden brown in colour all over. Remove and brush immediately with the olive oil.
Allow to cool on the trays before removing to a wire rack to cool completely. When ready to serve, stack on their sides in lined bamboo serving trays.
