These are simply The Best Flourless Brownies I’ve ever made! I’ve been tinkering around with them for 8 years now and I know you’re going to love these. They’re deeply fudgy, super easy to make, and just over the top delicious with a touch of flaked sea salt!

When I’m craving a brownie, what I’m after is a fudgy, ultra chocolatey experience. A little bit of chewiness and a lightly crackling top are also necessary part of the package. No fluffy or cakey brownies to be found here.

I found the perfect ‘better than the box’ recipe a few years ago. And I would make it from time to time for the occasional guilty indulgence. It was straight up white sugar, white flour, and all things processed though.

These days, I’m still wanting all that yumminess, but without the processed ingredients and loads of sugar. Now you might not think that would be possible, but I have the pictures to prove it most definitely is.

I originally saw the idea to use nut butter for baking from Elana’s Pantry. And ever since I baked my first brownies with nut butter, I’ve been using it to make all sorts of things ever since!

Nut butter acts as a ‘flour’ of sorts in baked goods. And I’ve had good success with everything from muffins to brownies and cakes. They’re all made with nut butter, and I’ve included them all below!

And just in case you were wondering about the fudginess…. I think this will clear things up! This is the double batch I talk about below in the tips section.

Now let’s jump in and talk about the ingredients for The Best Flourless Brownies!

  • Nut butter – Each nut butter I’ve tried has produced a different texture in these brownies. But you will have success with whatever one you choose. I’ve even had reviews from those who have made these with sunflower butter to avoid nuts altogether and had great results. My favorite ever nut butter to use is raw cashew butter. It will give you the best crackly top, and it has a lighter flavor to let the chocolate really shine through. It tends to be a bit more expensive, so I stock up every time it comes on sale. These brownies also work really well with roasted cashew or roasted almond butter as well which is a bit more accessible. Peanut butter is my last choice for brownies because it has the most assertive flavor. But check out my brownie recipes below for the peanut butter cheesecake ones if you want a peanut butter cup experience! Be sure that any nut butter you’re using is plain nut butter, (no sugar, oil, salt, etc. added).
  • Maple syrup provides both a bit of liquid and acts as the sweetener here.
  • Egg – binds both the nut butter and cocoa powder together to create the right chewy texture.
  • Avocado oil is my choice to keep these dairy free. And it also creates a great texture, especially with the raw cashew butter. I’ve also used melted salted butter, and melted ghee in this recipe as well. I’ve have used melted coconut oil, but it does add a coconut flavor which is why it’s my last choice here.
  • Baking soda – provides just a touch of leavening to keep these brownies fudgy, but not completely dense.
  • Cocoa powder – works together with the nut butter to provide structure. It works like a ‘flour’ in this recipe. And of course it’s also responsible for the chocolate flavor here. It also means you get to make brownies without any refined sugar at all which is a nice bonus!
  • Vanilla – just a touch of vanilla always enhances chocolate, and is a must in brownies.

Ok… let’s make The Best Flourless Brownies step by step in just minutes!

All the ingredients for the flourless brownies measured out.

Tips & Tricks:

  1. To get deep dish super thick brownies, make a double batch and bake them in a 11″x7″ deep dish baking pan. It will take about double the cooking time, around 45 minutes. You’ll end up with brownies that are about 3″ deep and oh so fudgy!
  2. If you want to be able to slice the brownies and put them on a serving plate, you’ll need to line your baking dish. The ones you see pictured below are a single batch baked in an 8″ baking dish. Line the baking dish with 2 strips of parchment paper. Then after the brownies have baked, let them cool on a wire rack until they’re firm enough you can lift the out of the pan. Or turn the pan to a 45º angle and carefully slide them out with the parchment paper.
  3. These freeze really well in an airtight container. If you want to stack them together in your container without them sticking, freeze them in a single layer first. Slice the cooled brownies, them set them apart on a parchment lined baking sheet. Freeze them until solid, then transfer them to a container where they’re keep for at least a month.

And finally some more flourless baked goods, all made from nut butter!

The Best Flourless Brownies


These easy to make brownies are super fudgy with deep chocolate flavor.



1 cup nut butter, see notes

1/2 cup maple syrup

1 egg

2 tablespoons avocado oil

1/2 teaspoon baking soda

1/4 teaspoon sea salt

1/4 cup + 2 tablespoons cocoa powder

1 teaspoon vanilla extract

Optional: flaked sea salt to sprinkle on top


Preheat the oven to 325F.

Lightly grease a 8″ baking pan. Or cut 2 strips of parchment paper the width of the baking pan and place them into the pan crosswise if you want to be able to lift the brownies out of the pan.

Add all of the ingredients listed into a medium sized mixing bowl. Mix until completely combined, then spread it evenly into the prepared baking dish.

Bake until puffed in the center and just done but still fudgy, about 20-25 minutes. 

Let the brownies cool completely on a wire rack before attempting to carefully lift them out. Otherwise let cool as long as you’d like before slicing and diving right in!


Raw cashew butter makes for the best crackly top and best chocolate flavor too. But I’ve also used roasted cashew butter and almond butter, and both are great. Just be sure the nut butter you choose doesn’t have anything added, (like salt, sugar, oils, etc.).

  1. Yowsers, Kari!! This is YUMMY!! Unbelievable! I am a convert! Of course, if I the whole batch in one sitting, that would not be healthy but for sweet treat this more than gets the job done. It is sweet but then you’re not getting any refined carb with the syrup so you’re not getting totally hopped up..

    • I’m so glad you enjoyed them! I was aiming to make something similar to the brownies I grew up with, and these taste almost the same except I actually like them better. I’ve found that the few times I’ve tasted desserts made with processed ingredients after having made the switch that they taste really bland compared to whole foods desserts. 🙂

  2. Hi Kari, If I use two pie pans what size did you have in mind? 8″ or 9″. Or could I use a 11″ x 7″ pan?

    Can’t wait to try this recipe!

    • I used 9″ pie pans or a 9″x13″ glass baking dish, and I updated the recipe to say 9″. I hope you enjoy the recipe, and be sure to let me know how it goes! 🙂

    • I’m so glad to hear that he like them! They’ve been a real favorite with my husband and I because they’re so similar to the traditional brownies we both grew up with!

  3. Today I made these Brownies. I made it with a mixture of Cashew, Almond an Coconutbutter, becaus I had bought to less, and we have in Germany very small Glasses (250 grams). Next time i will let them a bit longer in the oven, because they are now so moist, that I can’t get them out of the pan. But they are so tasty, and I hope, that my brother like them . My brother can not eat wheat, but loves brownies. I love your Blog.

    • These brownies are super moist and don’t quite hold together like traditional brownies, but baking them a little longer might help, I just enjoy mine super fudgy! 🙂

  4. I made these this weekend and they were a huge hit! Next time I will cook them a little longer but my coworkers loved them all gooey, none of them know they are Paleo!
