Preparing the Cookie Dough

1. Preheat the fan oven to 170° C (340° F).
2. Place the flour in a large mixing bowl and add the softened butter, baking powder, icing sugar, yogurt, and lemon zest.
3. Mix them with your fingertips gently until combined.
4. Return the mixture to a worktop and form a nice soft dough.
5. Roll the dough into a log and cut it into 5 equal pieces (approximately 140 grams each) and turn them into balls.
6. Lightly flour the worktop, sprinkle some flour on a dough ball, and roll it out into a 20 cm (8") dia circle (approximately ½ cm thick).
7. Cut the circle into 8 equal triangles and place a teaspoon of apple filling on the wide side of each triangle.
8. Roll them up into a log shape and place them on a baking paper-lined tray.
9. Bake for 20 minutes, until lightly browned.
10. Sprinkle some icing sugar on top when they are still warm.
