Mix the Flour,B. Powder, B. Soda together. Then in a bowl take powdered sugar, water and oil. Beat well until everything is mixed well. Add the Flour mix and make a smooth lump free batter. Add cinnamon powder and a pinch of grated nutmeg. Add a tsp of vinegar and vanilla essence too. Mix well and bake in a pre heated oven at 180-200 °C for 25-30 minutes. I have baked in a khadayi for 30 minutes. Keep aside to cool once done.
