Pre-heat the oven for atleast 10 to 15 minutes at 180 degrees C. Line a baking tray with parchment paper and apply ghee.
In a wide bowl, sift the whole wheat flour twice and then add Rolled Oats, raisins and baking soda.
Mix all the dry ingredients well using a spatula.
In another bowl, add the jaggery and melted ghee. Whisk well until the jaggery has mixed well and melted.
Add this to the bowl of dry ingredients and mix well. It will be dry and sticky. Now add a tbsp of milk and bring the cookie mixture together.
Initially the mixture will not bind well and appear non-sticky. Keep mixing gently with your hand and if necessary, add another tbsp of milk to bind everything together.
Gently shape and place the cookies over the tray. Grease your hands with few drops of ghee if you find it too sticky.
Bake the cookies at 150 Degrees C for 25 minutes in a pre-heated oven.
Allow the cookies to completely cool and then store them in an air tight container. Note - These cookies will appear soft after they are out of the oven. Allow them to cool so that they harden.
