Double Chocolate Brownies

Rich, fudgy, and packed with two kinds of chocolate—these double chocolate brownies prove that sometimes, simple is best. They may look unassuming, but one bite will have you hooked!

Some recipes remind me why simple is sometimes best. These brownies don’t need nuts, peanut butter, or caramel—just pure, deep chocolate flavor. And trust me, they don’t feel plain. (Quinn, my resident brownie purist, would argue that no brownie ever needs extras!)

This recipe comes from a favorite baking book of mine, one filled with tried-and-true cookies and bars. The editors call this one of their most popular brownie recipes, and after making them, I can see why. They’re soft yet rich, deeply chocolatey, and incredibly satisfying.

Why You’ll Love This Double Chocolate Brownie Recipe

  • Double the chocolate. A mix of semisweet chocolate and cocoa powder gives these brownies deep, intense chocolate flavor in every bite.
  • Soft and fudgy. These aren’t the dense, chewy kind of brownies—think light, tender, and melt-in-your-mouth good.
  • Satisfyingly indulgent. They’re rich but not overwhelming, so even a small piece is enough to curb your chocolate cravings.

The Key Ingredients That Make These Brownies Special

A few simple ingredients make these brownies rich, chocolatey, and perfectly soft:

  • Semisweet chocolate – This is where most of the deep chocolate flavor comes from. Choose a good-quality chocolate bar for the best results.
  • Dutch-process cocoa powder – Adds even more chocolate depth and a touch of bitterness to balance the sweetness.
  • Butter – Melted butter gives these brownies a soft, fudgy texture and enhances their rich flavor.
  • Eggs – Beating the eggs with sugar creates a slightly lighter brownie texture, making these softer rather than dense.
  • Salt – Just a little brings out the chocolate’s full flavor.

How to Make Double Chocolate Brownies

These brownies come together in just a few simple steps. The key? Gently melting the chocolate and butter together, then beating the eggs and sugar well for a soft, rich texture.

  • Melt the butter and chocolate. Warm them together over a double boiler (or use the microwave in short bursts). Stir until smooth, then let it cool slightly.
  • Mix the dry ingredients. In a separate bowl, whisk together the cocoa powder, flour, baking powder, and salt.
  • Beat the eggs and sugar. Using an electric mixer, beat them together until pale and slightly thickened—this step helps create a lighter texture.
  • Combine everything. Stir the melted chocolate into the egg mixture, then gently fold in the dry ingredients.
  • Bake! Spread the batter in a parchment-lined pan and bake until set but still fudgy in the center. Let them cool completely before slicing (trust me, it’s worth the wait!).

Tips for Success

  • Mix gently. Over-mixing is the quickest way to lose that soft, fudgy texture—once the flour is in, stir just until combined.
  • Use good chocolate. Since these brownies are all about the chocolate, you’ll taste the difference when you use one you really love.
  • Let them cool (if you can wait!). I get it—warm brownies are tempting. But letting them cool completely makes slicing easier and keeps them from crumbling.

Fun Ways to Change It Up

  • Love nuts in your brownies? Stir in a handful of chopped pecans or walnuts for a little crunch.
  • Craving even more chocolate? Add chocolate chips or chunks to the batter for extra melty goodness.

How to Store

  • Room temperature: Keep them in an airtight container, and they’ll stay fresh for about 3 days—if they last that long!
  • Freezer: Want to save some for later? Wrap individual brownies in plastic wrap, place them in a freezer bag, and freeze for up to 3 months. Let them thaw at room temperature or warm them up in the microwave for a gooey treat.

Want to Take These Brownies to the Next Level?

These brownies are amazing all on their own, but if you really want to go all out, try warming one up and topping it with a scoop of vanilla ice cream. A drizzle of caramel or hot fudge wouldn’t hurt either! If you’re a coffee lover, they’re also incredible with a cup of coffee or a tall glass of milk.

Double the chocolate means big, rich flavor in these double chocolate brownies. This easy brownie recipe will knock your socks off!

3 double chocolate brownies on plate

Ingredients

  • 6 tablespoons (85g) unsalted butter, plus more for pan
  • 6 ounces (170g) semisweet chocolate, coarsely chopped
  • 1/4 cup (21g) unsweetened Dutch-process cocoa powder
  • 3/4 cup (90g) all-purpose flour
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon coarse salt
  • 1 cup (200g) granulated sugar
  • 2 large eggs, at room temperature
  • 2 teaspoons vanilla extract

Instructions

  1. Preheat oven to 350°F. Butter an 8-inch square baking pan. Line the pan with parchment paper, leaving 2 inches hanging over the sides. Butter the parchment paper.
  2. In a heatproof bowl over a pan of simmering water, stir together the butter, chocolate, and cocoa powder until melted and smooth. Set aside to cool slightly.
  3. Whisk together the flour, baking powder, and salt. Set aside.
  4. In a separate bowl, combine the sugar, eggs, and vanilla using an electric mixer with a whisk attachment. Mix on medium speed until pale, about 4 minutes. Add the chocolate mixture and mix until combined.
  5. Reduce mixer speed to low and gradually add the flour mixture, mixing until combined.
  6. Pour the batter into the prepared pan and spread evenly. Bake for 35 minutes, or until a cake tester comes out with a few moist crumbs.
  7. Let the brownies cool in the pan for about 15 minutes. Then, use the overhanging lining to lift the brownies out of the pan onto a wire rack. Cool completely before cutting into squares.

  1. They look like quite a good brownie. Can’t really go wrong with a MS recipe. I really need to pick up that book sometime soon!

  2. sometimes all you need is a good ole chunk of brownie without any additions. you just want a nice big bite of pure unadulterated chocolate. that picture is mighty enticing too!

  3. These look great! As for the cocoa question, I just posted a double chocolate clafoutis recipe and I happened to put a link in it to my favorite cocoa that I found last year. It is a dutch process by a division of Callebaut. 100% Extra Brut Cocoa. It is very dark with a reddish tint. It tastes awesome every time I use it and I love the deep color. Anyway, you could google that name or just go to my blog for one of the links. I buy mine locally at a restaurant supply store that stocks it. Good luck!

  4. What can I say? I’m just hungry…. I want brownies and I want them now!!

    Thank you very much for sharing. I’m a fan of “bake or brake”. I don’t understand english completely well because it’s not my language but recipes are easy to read and make and your photos are great. (A so close approach to the brownie is… wow, amazing)

    Kisses from Spain.

  5. I bet these are good. .. The photos are amazing! I bought this book too but I haven’t made anything from it yet but I love the photography and food styling. The wedding cakes book is also stunning. and in regards to cocoa powder…I love valrhona cocoa powder. It is the best I have ever tried.

  6. Ooooh…my eyes just bugged out of my head when I saw that pic! You know, like the wolves in the old cartoons when they see a pretty girl? hehehe.

    Those look perfect.

  7. I have to agree with Quinn. A plain ole brownie is one of my fave’s, too. These look wonderful!

  8. RecipeGirl, I think this book is definitely worth it. I’ve got several recipes marked to try.

    Thanks, Amanda! Yes, sometimes only chocolate will do.

    Holly, thanks for the cocoa recommendation. I’ll be on the lookout for it.

    Morgana, thanks so much for visiting! I suppose food is a universal language. 🙂

    Alex, that’s certainly an interesting theory. 😉

    Aran, I’ve looked at that cocoa powder before. Thanks for the recommendation!

    Elle, I know exactly what you mean! Thanks!

    Thanks, Cindy!

  9. Have I ever mentioned that I want to marry you? Because I do. Many, many times over. Or perhaps you could adopt me? I could be your pet, even. I’m completely house-trained, and can fetch slippers for you, or, you know, spatulas.

    Just think about it.

  10. I guess yesterday was a brownie kind of day.

  11. Jen, I want to bake something for a friend and have been thinking of what to bake. I think I’ve just made up my mind!

  12. Oh dear…I’ve made and seen some good brownies before but THESE. LOOK. AMAZING!!!

  13. Indigo, I’ll certainly take all of that into consideration. 😉

    Anna, I guess it was. Great minds, right?

    Patricia, I hope you and your friend like the brownies!

    Hillary, thanks so much! They are really quite good.

  14. Oh… I haven’t made brownies in a while. Yours look delicious! So crispy on top. Hope mine will still taste ok without any of that premium chocolate! 🙂 I love fancy chocolate, but all I have right now is plain ol’.

  15. …drooling! These look yummy and the perfect mix of fudgey and squishy.

  16. Sarah, I’m sure they’ll still be delicious with whatever chocolate you have. I think I’m a bit obsessed with all these premium chocolates! 😉

    Thanks, Katie! A very apt description.

  17. Those are the most perfect brownies I have ever seen! Gorgeous! I’m going to try these out as soon as I can. I’ve been on the hunt for the perfect brownie, and I am thinking this is it!

  18. okay, so these are now added to my list of must trys. Besides, I’m also a fan of the just plain brownie. Actually, I think I should just be your taste tester.

  19. Oh … you need to change your tagline, too. You’re no amateur.

  20. what a torture is to look at your brownie. It looks fantastic.

  21. Ahh those look so good. The perfect chocolate fix. I wanted to get Martha’s new cookie book but I have some of her Christmas cookie magazines that have a lot of those recipes.

  22. Is Martha Stewart up to it again? Wasn’t it a Martha Stewart recipe you shared last that I went crazy for–a combination brownie/cookie? I believe it was the Outrageous Chocolate Cookie recipe, and now double chocolate brownies?! How much more can I bake before I have to break out “the Bean” to help work it all off?

  23. I love a good brownie with a cold glass of milk. This sounds like that kind of brownie. …mmm!

  24. I love how rich and almost gooey/creamy these brownies look! This is a great picture, it definitely captures what a classic brownie should look like. I would’ve taken a bite out of it before photographing it too, by the way! Definitely adds to the yumminess :).

  25. Those brownies look nice and moist and dense and good!

  26. Yep, thats me! Will be trying most defintely!

  27. Those brownies look divine! Wish I could take a bite of my computer screen right now 🙂

  28. Cafe Johnsonia, thanks! I hope you like them.

    Bakerella, I appreciate the compliment. Might I remind you that *you* are the one who appeared on Martha’s show. 😉

    Joanna, I certainly don’t mean to torture you! Chocolate is love!!!

    Ashley, I think most of that book’s recipes are recycled from other Martha sources, but I like having them all in one place.

    Sandie, those cookies were also from Martha. She knows her chocolate!

    Gigi, you might be on to something!

    Thanks, Sophie! Taking that bite was purely for artistic purposes. Sure, it was.

    Thanks, Kevin! They were indeed all of those things.

    Sathya, I hope you like them! Let me know what you think.

    Thanks, Stacie! Definitely one of my favorite all-chocolate brownies.

  29. So I tried out the recipe today…the taste is out of the world, texture is awesome but mine turned out a little thin. I love a thick brownie. Would doubling the recipe be messing with perfection. I am a big fan of the site.

  30. Laura, did you use a different size pan? I’m not sure why yours would have been thin. I think doubling the recipe would be fine, but you’d definitely have to use a different size pan. Maybe an 8″x 11″ if not a 9″x13″.

  31. OMG! That looks so moist and decadent!
    I’m a certified chocoholic and can never get enough of chocolate.

  32. TBC, thanks! I don’t think getting enough chocolate is conceivable.

  33. I made this recipe and i absolutely loved how it came out…. deliceous.

    i did combine this recipe with the idea of cooking the brownies in a muffin pan like you did for the peanut butter brownies (mostly cause i was mailing them and i knew if i had the cut them they would crumble)

    the brownies did not last long at all in my house so i definately have to make more. I am thinking of piping them into the pan for easier dispensing of the chocolate batter, and i also am thinking of maybe filling them with either a strawberry or orange marmalade

    i also really liked the semi cake-ey texture of the batter but it was still moist and delecious!
    thank you so much for posting these delecious recipees i absolutely love your blog

    ps. if you like my idea of marmalade filling you are more than welcome to take it i do not have a blog or any other way in which so share my ideas.

    lastly if you want to make this in the muffin tins i found the time to be aprox. 16 minutes for cook time.

  34. Jayme, I’m glad you liked them! I bet the small sized bites of them went really fast. The addition of marmalade sounds interesting! Thanks for the info!

  35. this looks good. haha(: im only** years old!!

  36. Could I make these with regular cocoa powder??

  37. Elizabeth, you might be able to substitute regular cocoa powder by adding more baking powder. If you Google for how to adjust the baking powder, you’ll find various suggestions. However, I highly recommend not interchanging the two kinds.

  38. Miam, it seems very good, you make me hungry! ^o^

  39. all i can say is: WOW. they are FABULOUS. no joke, go and make them right now. fudgy, rich, chocolate-bliss: i am in heaven.

  40. Did you know that I love any brownies without nuts.

  41. Nice recipe. I love a simple brownie recipe which is easy for the kids 🙂
    Thanks for sharing,
    Jane

  42. Whao, amazing. Just saw this on your Instagram page. Can I use regular cocoa powder instead of dutch processed. Also can I reduce the sugar by about 30g. 

    • As a general rule, I don’t like to interchange regular cocoa powder and Dutch process. In this recipe, it would likely work well enough, although you’re likely to find some difference in taste and texture. That small amount of sugar reduction will likely not have much effect, although your brownies may be drier than intended.
