That's true...The other day, I baked banana chocolate walnut brownies using Chef Michael Smith's recipe and i substituted oil for butter. They turned out absolutely yummilicious. I am not a fan of butter/margarine for two reasons; first because I don't like the smell and taste of them and second because they are not heart friendly.
That's right and Butter cakes are too dense whereas oil cakes are kinda fluffy and light.
