• Hi, these look delicious!  By any chance is there a substitute for espresso powder if I don’t have that on-hand?  I’d love to try these this weekend but won’t be able to get to a store by then.  I totally understand if not.  Thanks!

    1. Hi Rachel! You can swap a larger amount (I’d suggest 1 1/2 times) the amount of regular instant coffee, but if you don’t have that on hand either, I’d simply omit it. The brownies are still super delicious, even without it. For future, if it were a chocolate cake or muffin, you could use a tablespoon or so of really REALLY strongly brewed coffee and then subtract the amount you add from the other liquids, but since brownies don’t have liquids to subtract, I’d use instant coffee or just omit it entirely. I hope that helps!

      1. Thanks so much for the quick response.  I do actually have some instant coffee laying around so I will try that!  Great suggestion.  Thank you again! :) 

        1. I made these and they were delicious!!!  They were a big hit, so I will make sure to keep this recipe as my staple whenever I’m in need of brownies.  5 stars

          1. YAY!! I’m so happy to hear that Rachel. Thanks for trying the recipe and taking time to leave this wonderful review!

  • I wasted no time in making these.  Within a few hours of receiving the post in my email, these delicious brownies were baking in my oven.  I used Andes baking chips as my mix-in (omitting the chocolate chips), and the result was delicious!  Thanks for an easy, scrumptious recipe.5 stars

    1. I love your style Jocelyn! Life is too short to wait for brownies :) I’m sooooo happy to hear that you loved these. Thanks for trying the recipe and stopping back by to leave this review!

  • HI Erin, I’d like to make these for my sister-in-law who was recently diagnosed with celiac disease. Do you have any idea if GF flour would work as a substitute? She has had to radically change her lifestyle, lives in Canada and is coming for a visit. I’d love to surprise her! 

    1. Hi Marina! That is so sweet that you want to surprise your sister-in-law. I’ve never made these GF, but my best suggestion for where to start would be a 1:1 GF baking blend like this one: http://amzn.to/1TyLawC. Use 1/2 cup of it in place of the flour in this recipe. I hope that helps and that you both enjoy the recipe very much!

  • Hi Erin! I was wondering if you can swap the 1/2 cup butter for 1/2 cup coconut oil? My friend recently had a baby and her little boy is sensitive to milk so she can’t eat any. Would you still need to heat it and everything? Thanks!

    1. Hi Rachel! The flavor won’t be as rich (butter does add a lot to the flavor), but I think it would bake just fine. I’m not sure if she needs dairy free chocolate too? If yes, I’ve heard good things about Enjoy Life brand chocolate, though I’ve never tried baking with it myself. If you decide to experiment with coconut oil/dairy free chocolate, I’d love to hear how they come out!

      1. Hello again! So I made half a recipe with coconut oil instead of butter and chopped up baker’s chocolate that was 100% cocoa and it turned out great! However it did have a distinct coconut flavor but my friend really enjoyed them. I also did not heat the the coconut oil since mine was already melted. Thanks again for help!

        1. Rachel, thanks for reporting back! Did you use virgin coconut oil? I find the coconut flavor of it to be less pronounced, but I’m glad your friend loved them anyway!

      2. Yes, I used organic virgin coconut oil from Trader Joes but maybe I just have a sensitive palate ? Thanks again!

  • I made these tonight and added a chopped Hershey’s bar to the batter along with a handful of dark chocolate chips. Served them with cookie dough ice cream for my own take on Ben & Jerry’s Half-Baked – fabulous! Such a quick and easy recipe – will definitely be my go-to when the brownie craving strikes!5 stars

    1. Jenni, that sounds like a delicious batch of brownies! Thanks so much for taking the time to leave this awesome review and share your tweaks!

  • These turned out great! Thank you! I made them for a party tomorrow and wanted to know if you rec storing at room temp or in the fridge??5 stars

  • I wanted to make something from scratch but not too fussy for a coworker’s birthday and chose these brownies. They turned out amazing! My first time making brownies from scratch. Everyone was very impressed, and I was told they tasted like a mix between brownies, truffles, and fudge. Perfect description and such an amazing treat!5 stars

  • This recipe has ruined me for every box mix brownie. It’s just not the same once you have tasted the simple decadence of a homemade batch of brownies. Your recipe is the only one I make in my kitchen now!5 stars

  • I made the olive oil version of these, sprinkled with flaked salt. Delicious! My go-to brownie recipe from now on!5 stars

  • Hi! These look great but it would be so helpful to have metric conversions for those of us not used to cups! (Mostly Europe I think)

  • One Bowl Brownies are the best brownies in the world!!! I can’t say enough good things about their chocolately deliciousness and how easy they are to make. They are now my go-to dessert whenever I have company. Thank you Erin for introducing them to me and my family.

  • I didn’t use the double-boiler method. Instead, I melted the butter in the microwave, then added the rest of the ingredients. Took a little longer in the oven than the recipe instructs as well. They turned out FABULOUSLY. Super easy and one of only two brownie recipes I’ve ever made that are better than the boxed mix. This one’s a keeper!5 stars

  • These are the gooiest brownies I’ve ever had. Just what I was looking for! I was making sure I could use margarine and saw canola oil and thought, good enough. So good. Thanks for the recipe 🙌5 stars

  • These are really rich and really good! I find they aren’t quite as sweet as a lot of brownie recipes, which is a good thing. My family loves them!5 stars

  • I needed a quick brownie fix and mannnnn did this hit the spot! These are fudgy and rich and go amazing with a big glass of milk!5 stars

  • I’m stuck on the double boiler part .. trying to figure out a bowl to use .. I’m guessing glass would work?

  • Why does it say 6 teaspoons of salt for the 2x recipe! The brownies came out incredibly salty! Can you please change the proportions of the 2x and 3x so the people in the future don’t repeat my mistake? Thanks.

    1. Hi Chris! I’m sorry there was trouble with the 2x, 3x option. That is a plugin issue that I am not able to control on my end, but I did make a few tweaks in hopes that it will help for the future. Thank you again for letting me know.

  • This method looks interesting! Never seen it done this way! Going to try this out bc it looks amazing! Also, I love that you put photos of the step by step process in the actual recipe card! :D
    Thanks!
