Using oil instead of butter has some surprising benefits. For one, it can help cookies stay fresh for longer since oil doesn't go rancid as quickly as butter. It's also a healthier option, with many oils (like coconut or avocado oil) offering more heart-healthy fats than traditional butter.
But here's the thing: not all oils are created equal when it comes to baking. Coconut oil is a popular choice for its unique flavor and high smoke point, making it perfect for high-heat baking. On the other hand, olive oil can add a fruity and nuanced flavor to cookies, but its low smoke point means it's best used in lower-heat recipes.
