So, why does butter make such a big difference in brownies? It all comes down to the fatty acid content. Butter contains conjugated linoleic acid (CLA), which gives brownies a silky smooth texture and a more complex flavor profile. Oil, on the other hand, can make brownies feel greasy and one-dimensional.
But don't just take my word for it! Try making a batch of brownies with butter and see the difference for yourself. You'll be amazed at how much more flavorful and moist they are compared to their oil-based counterparts. And the best part? You can use salted or unsalted butter, depending on your preference!
