In a bowl cream together Granulated Sugar (50 gram), Brown Sugar (50 gram), and Coconut Ghee (100 gram). Beat in the Egg (1) until completely absorbed.
Stir in the Sourdough Starter (1/2 cup) and Vanilla Bean Paste (1/4 teaspoon).
Next sift in Cake Flour (125 gram), Salt (1 pinch), Baking Powder (1 teaspoon), and Desiccated Coconut (50 gram). Last add in the White Chocolate (to taste). The dough will be quite soft. Transfer it to your fridge for a few hours.
Preheat your oven to 350 degrees F (180 degrees C).
Next, drop about 2 Tbsp of dough onto a baking tray lined with parchment paper and bake in your preheated oven at 350 degrees F (180 degrees C) for 8 minutes (for chewier cookies) or 10-12 minutes (for more cake-like cookies).
Let the cookies cool down completely on a wire rack before storing them in an airtight container.
