Set your oven to 350°F. Spray a 9×13 pan or line it with parchment and let the edges overhang so pulling brownies out is a breeze.

Grab a mixer—stand or handheld. Beat the softened butter with sugar until it looks fluffy and light.

Crack in those eggs plus your vanilla. Keep mixing and scrape the bowl sides when needed. You want things to come together nicely.

In another bowl, whisk salt, cocoa powder, and flour until you see no lumps hiding out.

With the mixer on low, toss in some flour mix, pour in a bit of milk, more flour mix, then the rest of the milk, ending with the last bit of dry mix. Don’t overwork it—just blend until there’s no dry patch left.

Spread your batter in the pan so it’s even. Slide into the oven for 30 minutes. Let it sit for about half an hour once it’s out. You want the bars still a little warm for the next step.

Heat up butter, milk, and sugar in a saucepan on medium-high. Let it barrel up to a boil and keep it bubbling for a minute. Take it off the heat, dump in the salt and chocolate chips, and whisk fast until it goes glossy.

Right away, pour the hot fudge over the warm brownies. Use an offset spatula to spread fast before it sets. Let the whole thing chill for at least an hour before cutting.
