Best Cocoa Brownies and the Quest for the Best Cocoa Powder



How many batches of brownies can I bake over the course of a week? A lot. I've been testing different brands of cocoa powders.

Cocoa powder is something I have in my pantry but rarely give it a second thought. I buy the Ghirardelli because it’s the fanciest-looking cocoa powder on the grocery store shelf. Cocoa is (was) not something I would drive out of my way for.

When I was working on my icing for black and white cookies, the recipe specified Dutch processed cocoa. Interesting. That’s the Hershey’s stuff that I used to buy, right? I haven’t bought Hershey’s cocoa in ages but I remember it being Dutch processed. I found it strange when I saw a post on a cooking discussion board asking about where to buy Dutch processed cocoa. I thought Dutch processed was the common stuff.

After stopping by my local spice shop, to pick up some black onyx cocoa, I walked over to the grocery store to read the Hershey’s label. It was not Dutch processed! When did Hershey’s switch from Dutched to natural? I did find a Special Dark version next to the regular version. The Special Dark is a blend of natural and Dutched cocoas. I haven’t tried it but I hear it’s terrible.

So is natural better than Dutched? Some people seem to think so but in a blind taste test conducted by Cooks Illustrated, Dutched won in every single category. I found this pretty interesting. Apparently, by Dutch processing the cocoa, the cocoa tastes more “chocolatey.” The process neutralizes some acidic flavor notes and also produces a darker cocoa.

So in the taste test, Dutching was good but over-Dutching was bad. I read this after using the super-Dutched cocoa for my icing. I was very disappointed. I don’t know how to describe the flavor. It was flat, stale and burnt. I loved the color so my plan was to mix the black onyx with some Dutched cocoa. I bought a few different brands to test out.

I tested the cocoas using a cocoa brownie recipe by Alice Medrich.



Best Cocoa Brownies
By Alice Medrich BitterSweet

Yield: Makes 16 large or 25 smaller brownies

Cocoa brownies have the softest center and chewiest candylike top "crust" of all because all of the fat in the recipe (except for a small amount of cocoa butter in the cocoa) is butter, and all of the sugar is granulated sugar rather than the finely milled sugar used in chocolate. Use the best cocoa you know for these fabulous brownies.

10 tablespoons (1 ¼ sticks) unsalted butter
1 ¼ cups sugar
¾ cup plus 2 tablespoons unsweetened cocoa powder (natural or Dutch-process)
¼ teaspoon salt
½ teaspoon pure vanilla extract
2 cold large eggs
½ cup all-purpose flour
2/3 cup walnut or pecan pieces (optional)

Special equipment: An 8-inch square baking pan

Position a rack in the lower third of the oven and preheat the oven to 325°F. Line the bottom and sides of the baking pan with parchment paper or foil, leaving an overhang on two opposite sides.

Combine the butter, sugar, cocoa, and salt in a medium heatproof bowl and set the bowl in a wide skillet of barely simmering water. Stir from time to time until the butter is melted and the mixture is smooth and hot enough that you want to remove your finger fairly quickly after dipping it in to test. Remove the bowl from the skillet and set aside briefly until the mixture is only warm, not hot.

Stir in the vanilla with a wooden spoon. Add the eggs one at a time, stirring vigorously after each one. When the batter looks thick, shiny, and well blended, add the flour and stir until you cannot see it any longer, then beat vigorously for 40 strokes with the wooden spoon or a rubber spatula. Stir in the nuts, if using. Spread evenly in the lined pan.

Bake until a toothpick plunged into the center emerges slightly moist with batter, 20 to 25 minutes. Let cool completely on a rack.

Lift up the ends of the parchment or foil liner, and transfer the brownies to a cutting board. Cut into 16 or 25 squares.







Below are the cocoa powders I tried out. They were all Dutched except for the Ghirardelli . I prefer the Dutched over the natural. The Guittard and the Valrhona are very similar in color - both are a beautiful deep reddish brown color.


The color difference is very apparent between the Dutched and the natural. In the foreground is a batch made with Droste Dutched cocoa (the lightest of the Dutched variety) and in the background is the Ghirardelli natural cocoa.
