Brownies: they’re the rich, chocolatey home dessert that all of us know and love. They’re easy to whip up at a moment’s notice and almost universally loved — although brownie fans fight fiercely over cakey vs. fudgy and middle piece vs. corner piece.

The other great thing about brownies is how easy it is to customize them. You can dress them up or down, add texture, and mix in other flavors. You’ll find brownies everywhere from Michelin-star restaurants to corner diners. There’s simply no end to what you can do with them!

We’ve been enjoying brownies for a lot longer than you might think. The first recorded instance of brownie baking was the Palmer House Brownie, which was made for the World’s Columbian Exhibition in Chicago in 1893. The point was to make a small cake that could be easily boxed up and put into packed lunches. The Palmer House version included apricot glaze and walnuts.

Ever since then, we’ve enjoyed brownies by the tens of thousands, with customizations of all kinds. But if there’s one thing all brownie lovers can agree on, it’s that you want a rich and decadent flavor, and above all, it has to be extra chocolatey. Here are 40 of the tastiest brownies you’ll ever try.
