I had a day of baking battles — an embarrassing loss in the first round and a satisfying win in the second. I was experimenting with an intensely dark black cocoa powder I picked up during a spice and bulk-goods outing, folding it into a simple one-bowl brownie recipe I hoped would be perfect for gift-giving.
Round one went poorly: the butter separated, the batter never came together, and the result looked and tasted like coal. I also accidentally bumped the oven thermostat down to 200°F, which didn’t help. That batch went straight into the trash.
Black cocoa is no joke. After regrouping and doing some quick research, I found a straightforward fix: blend the black cocoa with regular cocoa powder, add a touch more flour (a detail I’d missed in the original recipe), and be careful not to knock oven knobs while juggling dishes. My countertop space is tiny, so dish-drying logistics are a real challenge, but the adjustments worked.
Round two was a win. These brownies are intensely chocolatey and satisfyingly fudgy. The black cocoa deepens and sharpens the chocolate flavor and gives the brownies a dramatic, midnight-black appearance — a striking and fun result. Best of all, this is one of the simplest one-bowl brownie recipes you can make.
Midnight Black Cocoa Brownies
Makes 16 2-inch squares
Adapted from Bon Appetit
10 tablespoons (1 1/4 sticks) butter, melted
1 1/4 cups sugar
1/2 cup unsweetened cocoa powder
1/4 cup black onyx cocoa powder (or substitute additional unsweetened cocoa powder if you prefer)
1/3 cup + 1 tablespoon all-purpose flour
1/4 teaspoon salt
1 teaspoon vanilla extract
2 tablespoons water
2 eggs, chilled
Preheat the oven to 325°F. Line an 8×8-inch pan with parchment and butter the paper.
In a medium bowl, whisk together the sugar, both cocoa powders, flour, and salt. Add the melted butter and stir with a wooden spoon until combined. Stir in the vanilla and water until evenly mixed. Add the eggs one at a time, beating vigorously after each addition, then continue stirring until the batter is smooth and glossy. Work the batter well to achieve a shiny texture.
Pour into the prepared pan and bake 35–40 minutes, or until a tester comes out mostly clean with a few moist crumbs attached. Cool completely before slicing, or chill in the refrigerator for a couple of hours to get extra-clean cuts.
