These chewy brownies are based on a recipe from the March/April 2010 issue of Cook's Illustrated, where CI claims that the key to making brownies with a "box brownie" texture is to get the ratio of saturated to unsaturated fat just right. To get the chewiest brownies, they use a mixture of butter and oil, unsweetened chocolate and egg yolks.

Minor Little Issues
For a while, every time I made these I could taste the oil and couldn't understand why it didn't bother other people. I finally gave up on canola and vegetable and just started using grapeseed. Much better. I also used coconut oil, which made perfectly good brownies, but changed the texture since the point of the recipe is to use a ratio of 28% saturated and 71% unsaturated fat. And then there was the thinness issue. I'm not sure why the brownies were coming out too thin at one point, but recently they've been just right. Maybe it's perspective? I don't know. Lastly, there is the bake time. CI recommended 30-35 minutes. With a 9x13 inch pan you can I can get away with 30, but with a half batch in an 8-inch pan the brownies are better at 28.
Use Good Cocoa Powder
The article itself is pretty fascinating, and if you can get your hands on the March/April 2010 issue it's worth a read. But for now I'm just posting the recipe as I made it which is a smaller 8 inch pan version. This batch was better than any batch I've made in the past (though I didn't get a flaky top) and it might have to do with the fact I used a high end (Callebaut Dutch) cocoa powder. Not that using expensive Dutch process cocoa powder is always better since it has a drying effect in some recipes, but in this recipe it works perfectly. Update: I incorporated a little black cocoa in with the Dutch and loved the results. I'll bet you can tell which brownie has the black cocoa.
Pan Size
You can use a 9x13 inch pan and make the full size recipe or cut it in half and use an 8-inch square. As much as I'd love to make 9x13 inch pans, more often than not I just make a half version.

Chewy Brownies
Ingredients
- ⅓ cup Dutch-processed cocoa (28 grams)
- 1 ½ teaspoons instant espresso powder
- ½ cup plus 2 tablespoons boiling water
- 2 ounces unsweetened chocolate. chopped (56 grams)
- ½ cup plus 2 tablespoons oil (110 grams)
- 4 tablespoons unsalted butter, melted (56 grams)
- 2 large large eggs plus 2 large yolks
- 2 teaspoons vanilla extract
- 2 ½ cups sugar (500 grams)
- 1 ¾ cups all-purpose flour (250 grams)
- ¾ teaspoon salt
Instructions
- Preheat oven to 350 degrees F. Line a 9x13 inch metal pan with nonstick foil parchment paper.
- In a mixing bowl, whisk together the cocoa, espresso powder, and boiling water until smooth.
- Add the unsweetened chocolate and stir until melted. Stir in the oil and melted butter. (Mixture may look curdled.) Add eggs, yolks, and vanilla and continue to whisk until smooth.
- Whisk in sugar until fully incorporated. Add flour and salt and mix with rubber spatula until combined. Fold in chocolate chips (or chopped chocolate).
- Scrape batter into pan and bake for about 30 to 35 minutes. If halving the batch, check at 25 minutes, but it will probably take up to 30.
- Let cool for about 10 minutes, then grasp foil, lift from pan and let cool completely.

Sue, I am really interested in hearing your opinion.
Joe, it also might be that I whisked the eggs rather than stirred them. I've read that adding sugar to hot fat helps with sheen, but Shirley Corriher says the crust comes from the beating of the eggs. However, these brownies aren't beaten -- just whisked. So I'll try again and really whisk the egg.
Katrina, I forgot you made these! I'm going to go take a look at your photo.
Gloria, they're not. I've been nit-picky about thickness ever since one of my 11 year old tasters (not Fuzz) told me brownies should be thick.
Gloria says
Simple is good!! These don't look too thin to me...they look nice and chewy!
Katrina says
I tried these a few months ago. They were a really good brownie. Can't remember if I posted them.
Joe says
Wonder if you'd get that flaky top if you added the sugars to the fat (warmed?) first, rather than adding it as the fourth-to-last ingredient.

Definitely one to try!

I'm always interested in a simple home made brownie recipe. I can't believe I never tried these. My husband is a big fan of brownies and he tends to like them without too many add ins or stuff on top.
