Let’s be honest: butter is a drama queen. It has water in it (about 16-18% water, for you nerds). That water turns to steam, which makes things fluffy.
But a brownie shouldn’t be fluffy like a cloud. A brownie should be dense, sticky, and almost suspiciously moist. That’s where oil comes in.
Oil is 100% fat. Zero water. Zero funny business. It coats the flour particles perfectly and keeps everything softer for days. Your brownie won’t turn into a dry brick by day two. Promise.
The Texture: Let’s Get Real
Have you ever bitten into a brownie that crumbled into a million sad bits? That’s butter’s fault. Butter solidifies at room temperature, so your brownie gets a little tight and crumbly.
Oil stays liquid at room temp. That means every bite stays soft, bendy, and almost silly with moisture. You know that gooey, center-theatre-square piece? Oil makes the whole brownie that good.
I’m not exaggerating. Try it once, and you’ll be side-eyeing butter next time. "Sorry butter, you’re just not rich enough for this job."
