Boxed Mix Brownies

P1180574

Does a week of brownies sound good to you? I’m in a brownie mood and I’ve got a bunch of recipes to try out. Yesterday I posted the deliciously fudgy cocoa brownies. And now, to be enjoyed on Oscars night: boxed mix brownies. Cook’s Illustrated succeeded in recreating that famous boxed mix flavour from your Betty Crocker-filled childhood.

These boxed mix-inspired brownies have an all-natural, rich, deep chocolate flavour. They have a shiny crackly surface and a chewy texture that balances between cake-like and fudge-like. To avoid a greasy result, Cook’s Illustrated replaces some of the oil with egg yolks. The yolks’ emulsifiers prevent the fat from separating and leaking out while the brownies bake. To enhance the chocolate flavour, some of the butter is replaced by unsweetened chocolate since they have similar ratios of saturated to unsaturated fat. Chunks of bittersweet chocolate are folded into the batter to add pockets of melted chocolate to the brownies.

If you are using a glass baking dish, let the brownies cool in the dish for only 10 minutes. Remove the brownies from the dish at that time to avoid over-baking due to glass’s superior heat retention.
