I have followed the following recipe for my brownies:
Ingredients:
- 1/2 cup sunflower oil
- 3/4 cups sugar
- 2 eggs
- 2 tsp vanilla extract
- 1/2 cup flour
- 1/3 cup unsweetened cocoa powder
- 1/4 tsp baking soda
- Oreos (about 15)
However, the batter didn't seem enough for my 9" x 9" brownie tin. What can I add to make the batter consistency cover my entire tin? Because at the moment my brownies have become really flat and have not risen. What am I doing wrong?
