Have you ever noticed that baking with butter differs in your dessert’s texture than baking with oil? I don’t just mean boxed mixes, but baking from scratch.
Yup, I noticed it and a website confirmed it. Oil does make your desserts moister. Butter is good, too, at times, such as when baking cookies (depending on the recipe, especially if you’re trying to bake healthier stuff) and making buttercream icing. Butter is also good at flavoring certain sweets, like yellow cake when mixed in.
However, you usually don’t have to melt oil (unless it’s solid, like coconut oil) or heat it up. When cooking or baking with butter and having to add eggs, you have to use extra care. Melted butter has to be cooled to lukewarm before you add the eggs. Otherwise, you’ll end up with scrambled eggs in your dessert (this has happened to my mom and even me when I cooked vanilla pudding from scratch) and will probably want to throw it away.
Of course, everybody has different preferences. Some people are happy with just using butter. Others will enjoy using oil in their baking, regardless of reason.
