Can I use Dutch-process cocoa powder?
Yes. Dutch-process tastes smoother and a little less sharp than natural cocoa. This recipe works with either. If you have a strong preference for that classic brownie flavor, go with natural cocoa. If you love a darker, smoother chocolate vibe, go Dutch.
Why did my brownies turn out cakey?
Usually it’s one of three things: too much flour (scooped and packed), overmixing after adding flour, or baking too long. Spoon flour into the measuring cup and level it, mix just until you stop seeing dry streaks, and pull the pan when the center still looks a little underdone.
How do I get a shiny, crackly top?
Whisk the sugars into the warm butter and cocoa until glossy, then whisk the eggs in vigorously. That dissolve-and-whisk step is what helps create the thin, shiny crust.
Can I add chocolate chips or nuts?
Absolutely. Add up to 1 cup total of mix-ins. I love 1/2 cup chocolate chips plus 1/2 cup toasted walnuts for peak texture.
What pan size should I use?
A 9-inch square metal pan is the sweet spot. An 8-inch pan makes thicker brownies and needs a few extra minutes. A 9x13 pan makes much thinner brownies and will bake faster. If you want a similar thickness in a 9x13, make a 1.5x batch.
Metal or glass pan?
Metal bakes more evenly and gives you better edges (my pick). Glass can bake a bit slower and sometimes browns the edges more aggressively by the time the center sets, so start checking a few minutes early and use the doneness cues below.
How do I get cleaner slices?
Let them cool completely, or chill the pan for 30 minutes. Then use a sharp knife and wipe it between cuts. It’s a tiny move with big “bakery square” energy.
