Well, not exactly, my friend. You see, when you use butter in your brownies, it helps to create a tender crumb and a flaky texture. On the other hand, using oil can result in a denser and more fudgy brownie. So, if you want to sub butter for oil, you'll need to make some adjustments to your recipe.
One thing to keep in mind is that butter has a higher smoking point than oil, which means it can handle high temperatures without breaking down. Oil, on the other hand, can become overheated and smoky if you're not careful. So, if you're going to use oil, make sure to keep an eye on the temperature and adjust the baking time accordingly.
