Can you sub oil for butter in a brownie?

While you can technically replace butter with oil in brownies, there will be some differences in the texture and consistency of the final product. Here are a few things to consider when swapping butter for oil in a brownie recipe:

- Texture: Butter is a solid at room temperature, while oil is a liquid. This difference will affect the texture of the brownies. Brownies made with oil will be slightly denser and more fudgy, while brownies made with butter will be lighter and cakier.

- Flavor: Butter has a rich, creamy flavor that can't be replicated with oil. Brownies made with oil will have a more neutral flavor. To add flavor to your brownies, you can add vanilla extract, chocolate chips, or other mix-ins.

- Moisture: Butter contains water, while oil does not. This difference will affect the moisture content of the brownies. Brownies made with oil will be slightly drier than brownies made with butter. To add moisture to your brownies, you can increase the amount of liquid in the recipe, or you can add sour cream or yogurt.

Overall, swapping butter for oil in a brownie recipe is a matter of personal preference. If you are looking for a lighter, cakier brownie, use butter. If you are looking for a denser, fudgier brownie, use oil.
