Heat your oven to 180 degrees celsius.
DIce the apple into small cubes (5mm) I leave the peel on, but remove the core.
Cream the butter and sugar, I use my stand mixer for this but you can use a handheld beater or a wooden spoon and some elbow grease.
Add the apple sauce and vanilla, beat.
Add the flour, oats, baking powder and cinnamon. Mix until combined, I do this in the stand mixer on low speed.
Fold in the diced apple and raisins
Scoop your cookie dough into 12 even portions, roll into balls, place on a lined baking tray, then flatten them gently with a fork.
Bake at 180 degrees celsius for 12 minutes until lightly golden brown on the edges. The cookies will be soft, cool for 5 minutes before removing from the baking tray.
