For several years now, I’ve been pursuing the perfect brownie. Most brownie aficionados battle over fudgy vs. cakey or center vs. edge (speaking of which, are you aware of this piece of kitchen equipment?). My quest, though, is all about the flaky, shiny top. The perfect brownie, for me (aside from being fudgy-but-not-too-fudgy-and-definitely-a-center-piece-thanks-very-much), has a deep chocolate flavor, fairly dense texture, but then a crispy, wafer-like layer that magically forms during baking and, once cool, reflect the light back as you gaze lovingly at it before gobbling it up.
But the recipes I’ve tried don’t always have that result. I’ve definitely accomplished the deep, rich chocolate flavor, but the shiny top crust eludes me. I’ve tried suggestions to beat the eggs a long time, getting them really foamy, and I’ve read several ideas about chocolate chips, rather than unsweetened chocolate, as the source of the flaky shine. I haven’t yet achieved it myself, though.
But as of last weekend, I’ve come really close. There was a hint of a top layer, just barely flaky, and though it wasn’t consistently shiny, I could see the barest shimmer in a few spots. Like the tarte au citron au David Lebovitz a few months ago, this isn’t my recipe. It’s from King Arthur Flour. But I’m offering a suggestion or two and one very worthwhile addition, so that ideally our next pan of brownies comes out perfect.
KAF relies on two sources of chocolate in their mix: unsweetened cocoa powder, and the aforementioned chocolate chips. It seems the chips add just enough additional fat and sugar to the mix to help form that flaky sheen as the brownies bake. KAF also requires you to melt the butter and partially dissolve the sugar before bringing the batter together. It’s a little extra work, but getting the sugar dissolved faster is evidently part of the magic.
The recipe I’m linking to below suggests melting the butter, then stirring in the sugar and bringing it up to 110-120F, mixing that into the egg and cocoa mixture you’ve already created, and then dumping in flour, 2 cups of chocolate chips, and stirring “until smooth.” I surmised this means until the chips have melted into the rest of the mixture, but for me, by the time I was stirring in the chips the rest of the batter had cooled down enough that there wasn’t enough residual heat to melt them, and I didn’t want to keep mixing lest I start developing the gluten in the flour and end up with tough brownies. So next time, and what you might try in the meantime, is to add the chips right into the melted butter and sugar mixture. Stir them up to get them good and melted before combining with the rest of the ingredients. Maybe that, at long last, will produce the shattering shininess I’ve been craving.
One other adjustment to KAF’s already delicious recipe: for added interest and to cut sweetness a bit, I dumped in a heaping cup of tart dried cherries along with the chips and flour. My tasters found this an extremely worthwhile addition; studded with tart little pops, the brownies become more complex in flavor, and the cherries plump a little during baking and stay moist for several days afterward. I considered steeping the cherries in brandy for a half hour or so before mixing them in, but one of my taste testers is pregnant, so this time around I skipped the booze and was perfectly satisfied.
If you would like to add cherries, as I did, mix 1 heaping cup of tart dried cherries (such as Montmorency) into the batter along with the flour, then proceed as in the KAF recipe.
