No flour? No problem. The richest, fudgiest brownies you’ll ever bake don’t actually need it. The key to keeping these decadent one-pot brownies flour-free is cornstarch, and a combination of cocoa powder and melted chocolate give them their incredible chocolatey personality. The recipe calls for unsweetened natural cocoa; however, you can use Dutch processed if that’s what you have on hand (the flavor will be slightly different—but still delicious). With this flourless brownie base, you truly can’t go wrong—so while it’s not required, we highly encourage adding your favorite mix-ins. We found that peanut butter cups take these fantastically fudgy brownies over the top (in the best way). Find more tips for baking perfect brownies in this guide.
