- Sift flour, baking powder, baking soda, corn flour, and salt together. Set aside.
- Beat yogurt, sugar, milk, butter, and oil until sugar dissolves.
- Add the flour and stir gently. Do not mix more than 10 – 15 seconds.
- Pour the mixture in a greased baking pan. (I used baking paper). Bake for 40 minutes or until the toothpick inserted in the middle of the cake comes out clean.
