What can I substitute vegetable oil with in making brownies?
Olive oil has too strong a flavor to be put in brownies. I would imagine that your vegetable oil is probably ok. You could also melt the equivalent amount of butter or margerine and use that; 1 stick = 1/2 cup of oil. I always use real butter in my brownies, and they taste a LOT better, even if it does mean that I have to go easy because of the cholesterol!
