BB Monday: Cook’s Illustrated Chewy Brownies

Happy Monday!

How was your weekend? Are you running around crazy like a chicken with its head cut off? I am. So much to do and Thanksgiving is only 10 days away! Eeek!

But today is Monday and it’s time for another brownie recipe. This week I chose to make Cook’s Illustrated Chewy Brownies.

I have to confess, I was both excited and apprehensive to try this recipe. Excited, because there is “chewy” and “cook’s illustrated” in the name. Apprehensive, because there is “cook’s illustrated” in the name. Which means that these brownies could be perfect and I could end my search right now. And I am not ready to do that just yet.

Just look at it! Crackly top, chewy center, lots and lots of chocolate! Are you melting already? Then wait because there is another plus to this recipe. It comes together really quickly and you only need one bowl and a whisk. No bain marie, no mixer, no vigorous whisking until your hand falls off.

Then there is the hard part….. Waiting for them to cool. And they need to cool completely for the ultimate chewiness. Even though warm brownies are sooo goood, it is recommended to let them come to room temperature or they will be a mess to pull out of the pan. Then again, who will judge you if you just eat them straight out of the pan. And watch “Walking Dead” in the same time. Not me, ladies and gentlemen. Not me.

Only one thing I would add to these brownies. A sprinkle of sea salt on top. These babies are so rich and fudgy, hence the milk bottle. You will need it!

What I learned about brownie while researching this recipe:

- the texture of brownies depends on a combination of saturated and unsaturated fats ( hence the combination of butter and oil, but also chocolate )

- egg yolks prevent the excessive greasiness of the finished product

- if you are baking in a glass dish it is recommended to cool the brownies in pan for only 10 minutes and then remove to wire rack to cool completely; this prevents brownies from further baking and drying out

I have to say, these brownies taste and look as if you made them from the box. They are easy to mix together and chewy.

So, even though these are quite perfect, I am not declaring the winner. Instead, I am taking all I have learned while making these brownies and keep them in mind during this series.

Have a fabulous day!

    • I am always looking for the crackly top – it’s like a sign that the brownies recipe is good! Thanks, Emily!

  1. YUMmm! I even had brownies last night, I just might have to have them two nights in a row!

  2. Ohmygoodness! Anna, these are wonderful looking. I know I’d totally not be able to wait until they cooled. I’d take a burn to the roof of my mouth for these. Yes, yes I would! lol xxx

  3. What sort of tray/dish do I bake them in, is a metal one okay? + what sort of flour? Could I use wholemeal or does it have to be self raising/all purpose? Oh and can I use brown sugar, if not whats the best sugar to use.. thanks sorry for the extra questions!!!!

    • Hi Nellie! I used a metal pan but a glass one will be just fine. The flour I used was all-purpose ( as in the original recipe ) but you can try other. It may affect the texture though. If you want to get the results I had it’s best to keep to the original recipe. It is not recommended to substitute brown sugar for granulated sugar as they will affect the final product. Hope this helps! Thank you!

  4. Hello! I just stumbled onto your blog and was planning on making these, however, I don’t see an oven temperature listed? I assume the oven should be set at 350? Thanks.

    • Hi Taylor! Yes, you are absolutely right! Thanks for catching that! Let me know how the brownies turn out!

      • Anna, I just had them…words cannot explain how wonderful they are! They are the best brownies I have ever eaten :) Thanks for posting!

        Also, I love your photography skills–your photos are wonderful!

        • Yay! I am so happy you enjoyed them, Taylor! And thank you for your kind words about my photography! xoxo

  5. Stumbled on this post on Pinterest today and made them on a whim. Very sweet. Spot on review, they taste like boxed, but in a good way. Thanks for the recipe!
