In a bowl, sift the flour with icing sugar well. Add the vanilla essence and mix. Then, add the cocoa powder and combine everything.
Melt the vanaspati, butter. Then, slowly mix in the melted vanaspati to the dough. This needs to be done with small quantity and you need to keep rubbing it to get that crumble texture. Finally, add the butter and continue kneading the dough.
Press the Convection mode in your Microwave, increase the temperature to 185 degrees. The time duration for preheating is taken care of automatically by the microwave oven.
Keep kneading in the dough and continue till you get a dough that is soft yet stays in shape. Make big balls, dust your palm and the board with flour, press out to 1 inch thick sheets. Using the cutter, press on the sheets.
Once all the cookies are shaped out, place them on the tray. Grease the tray if required, else you can place it as such as the biscuits will let out oil during the baking process.
Once you have placed all the biscuits on the tray and the timer on the preheat goes out, place the tray inside the microwave oven and bake for 15 minutes.
After 15 minutes, you can let it rest for a few minutes inside the oven. Then, remove and allow it to cool before storing it in an airtight container.
With 2 cups of flour, I got two batches of 40 small-sized biscuits. Once the cookies are cooled a bit, transfer them to the wire rack and bake the second batch.
