You could use the same batter to make butter cake, pour the batter on a greased cake pan and bake it for 20-25 minutes.
My mom makes this cake in the pressure cooker:
Pressure cooker Butter Cake:
1.Make the batter following the above mentioned method.
2.Pour the batter on a greased cake pan.
3.Place the cake pan on a cooking rack that comes with the pressure cooker or any rack or flat steel plate and keep it inside the cooker.
4.Close the pressure cooker with its lid, without the sealing ring and the whistle and don't add water into the cooker (this is not steam cooking).
5.In low heat, cook the cake for about 30 minutes or until its cooked.
