Put all ingrediences together apart from baking powder into mixing bowl and whisk for about 2 minutes. Until it's mixed thoroughly. Then add baking powder and mix for about 10 seconds. You should have nice wet mixture. Best to use round cake tin which should be greased and dusted with flour to prevent sticking. Spread the mixture over the tin and level it up with pallet knife. Bake in our premium combi oven for about 30 minutes. To check if baked you can put metal skewer into cake if it comes out clean. Otherwise add few more minutes. Let it cool and use as desired. Good for birthday cakes.
