Low carb keto chocolate banana brownies are super moist thanks to coconut milk. Almond and coconut flour make them a delicious diary-free and Paleo treat.
Originally, I developed this recipe to be a low carb Chocolate Banana Bread. After preparing it in mini loaf pans, as muffins, and in a regular sized loaf pan, I decided it would make amazing low carb brownies. The texture is moist and fudgy and delicious.
Don’t get me wrong, the recipe works beautifully baked in loaves or as muffins, but the texture — oh, the texture! I have never eaten anything so moist in my life. To call it a chocolate banana bread or cake did not do it justice. With a texture so rich, moist and fudgy, chocolate banana brownies was perfect.
The banana flavor does not overwhelm the chocolate and the texture appears cake-like in the photos, but deceives. The first and second time I made this recipe I used my favorite mix of Bensdorp and Black Cocoa from King Arthur Flour and the color was so dark they did not photograph well. Using regular Hershey’s Cocoa resulted in the color you see pictured here, which is pretty dark. Both were good, but I preferred the flavor of my cocoa mix just a teeny bit more.
These uber-moist keto chocolate banana brownies would make the most awesome base for a sundae!
I just want to say a few things about the recipe before you run-off to make these!
[LOW CARB BAKING INFO] Low carb baking is different than regular baking. It took me several years to forget what I knew about regular baking. Once I did, my low carb, gluten-free and dairy-free recipe have become better for it.
My batters are much thicker than regular batters – this provides structure with out having to add gums and other thickeners. I use a minimal amount of Erythritol, Swerve or Xylitol. These ingredients are expensive so I use less of them and augment with Stevia Glycerite, which is a very concentrated sweetener. All of my baked goods are much less sweet than traditional items. That’s how I like it. Add more sweetener per your taste. Lastly, baking is fun – enjoy!

Low Carb Keto Chocolate Banana Brownies is an out-of-this-world recipe that is not only gluten-free but dairy-free and Paleo, too. Chocolate and Bananas? Yes, please!
- 2 cups (190 g) Almond Flour
- 1/3 cup (35 g) Coconut Flour
- 1/3 cup (45 g) cocoa powder
- 1/2 cup Sukrin 1 (or Swerve Granulated)
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 (5 oz/140 g) medium over-ripe banana
- 1 teaspoon vanilla
- 1/4 teaspoon maple extract
- 1/4 teaspoon banana extract (or almond or chocolate)
- 1/2 teaspoon stevia glycerite
- 3 large eggs
- 1/4 cup full fat coconut milk
- 1 tablespoon vinegar
- 1/2 cup walnuts
- 3 tablespoons Lili's Sugar-free Chocolate Chips or your favorite low sugar chocolate
- Preparation: Preheat the oven to 350 and position the rack in the lower third of the oven. Spray a 9 x 9 inch square brownie pan with cooking spray. Cut a piece of parchment paper wide enough to cover the bottom of the pan, come up the sides and drape over. Position it in the pan. Chop the nuts.
- Method: Measure and add the dry ingredients to a medium bowl and whisk together until combined. Add 2/3 of the nuts, stirring them in. In a smaller bowl, mash the banana with a fork - then add the flavorings, the eggs one-by-one, the coconut milk, and vinegar mixing in between additions. Scrape into the bowl with the dry ingredients and mix with a hand mixer until completely incorporated.
- With a spoon, place the batter evenly around the brownie pan. With the back of the spoon, gently distribute the batter in the pan - it is very thick and you will not be able to distribute it evenly with the spoon. Cut a piece of waxed paper and spray it with baking spray. Lay it over the batter and VERY GENTLY, with a sliding motion, use your fingers and hands to distribute the batter as evenly as you can. It just takes a minute and it won't be perfect -- don't worry, it will fill-in as it cooks. Add the rest of the nuts and all of the chocolate to the top, barely pressing them into the batter.
- Bake: Place in the oven and cook for about 25 minutes. The chocolate banana brownies are ready when the top feels springy, but not soggy and wet, when lightly pressed with a finger.

These are very good. I’ll add this recipe to my book. I did use 3 duck eggs somthey were more cakey but no problem!
Kim says
Wow, duck eggs! Glad they were still good despite the recipe change! 😀 Have a great day. -Kim
Karen A says
These are WONDERFUL, I’ve past it on to 2 low carb friends!
Kim says
I’m so glad! Thank you, Karen! -Kim
amber says
Can the coconut milk be subbed with hwc? These look so amazing, I will eat zero carb all day to eat these at night!!!
Kim says
Sure, you can sub. I would actually do 3 parts cream and 1 part water, since coconut milk is a little thinner. I haven’t tested the recipe with the HWC but it should sub fine. These blotter is super thick so spread it into the pan quickly before it thickens more as it sits. I hope you like them. -Kim
Maria says
Hello, these look terrific! Going to be trying them in the next day or two, curious what purpose the parchment serves. Is it mainly for the bottom? I only have a round pan and not looking forward to trying to line the whole thing lol 🙂
Kim says
Hi Maria. Cut out a circle so that it doesn’t stick to the bottom of the pan. The brownies are extremely moist and fudgy. Cut around the edge when they are ready to be cut and removed from the pan. Enjoy! -Kim
Maria says
perfect! thank you!
Kim says
Awesome. Have a great day! -Kim
Kelly says
Hey Kim, I want to try this recipe for a dinner party this week. I’d like to use a combo of almond meal and hazelnut meal. What are your thoughts of using both in this recipe?
Kim says
Kelly, for some reason, ground walnuts popped into my mind. They are lower in carbs like hazelnut meal and are more moist than hazelnut meal. If you have almond flour (blanched, ground almonds) you will have a better results than using almond meal (ground almonds with the skin). I’d say go for it. Let me just say that you are brave not testing the change before bringing! 🙂 I know the recipe as written is really good, but I can’t guarantee the tweak. Let me know how it tastes with the hazelnut meal because I love how the combination sounds. Have a great week! -Kim
Kelly says
Thanks for the reply Kim. I have the super fine blanched almond meal. If the hazelnuts are drier, I certainly don’t want a dry dessert.
Kim says
Hi Kelly. It’s not really that they are “drier” but have more texture, I guess. They might be really great in the recipe! The recipe is so fudgy that it might not make a difference. I’m sorry if my response sounded off. My children are home for the Summer and one of them honestly doesn’t stop talking or making noise from morning until night. I’m interrupted at least every 30 seconds. It’s not good for coherent thought…. Try it and see if you like it. It’s only cooking. 🙂 Have a great day and thanks for your understanding. -Kim
Linda Dixon says
What is a sub for stevia glycerate ?
Kim says
Hi Linda, great question. Use more sweetener or liquid stevia to taste. 🙂 -Kim
Rhonda from Baddeck says
These are magnificent! I substituted heavy cream for coconut milk (because that’s what I had), and used only almond flavoring. They are incredibly moist and delicious. Thanks for putting the weight measurement required for the bananas (6 oz.) because the first banana I mashed was only 3.7 oz and that would have made the brownies too dry. These are definitely doing in the “Keeper” file!
Kim says
Rhonda, I’m so glad you liked the brownies and I love that you used the almond flavoring! Yum! Thank you so much for taking the time to leave a comment. You made my day! Have a great weekend. -Kim
Dee says
I have a question about the banana as well.
Wondering if sour cream can be subbed?
Kim says
Dee, I have never tried subbing sour cream for the banana because I intended to use the banana; which lends extreme moistness and subtle flavor to the banana bread brownies. You can try, but I don’t know the results would be as it would completely change the recipe. If you just don’t like bananas I think that subbing canned pumpkin would work. If you want another brownie recipe you can try this one https://www.lowcarbmaven.com/fudgy-keto-brownies/ . Please let me know if I can answer any more questions. 🙂 Have a great weekend! -Kim
Darla says
These look soo yummy! Does the banana serve any truly necessary purpose? I only ask because of diabetes… I try to stay away from fruit.
Kim says
Hi, Darla. Great question. Yes, the banana makes the brownies so fudgy – it is important. You could try to sub canned pumpkin and lower the carbs by almost 1 gram and use Lily’s chocolate chips which would also help. I developed the recipe before I knew about Lily’s sugar-free chocolate chips. I hope this helps. -Kim
Patti C. says
I just found your blog, as I’m constantly researching almond flour low-carb recipes, been eating LC 6 mos (I’m fighting pre-diabetic sugar levels). Your site and recipes look “out of this world” good and I can’t wait to try them. I’m impressed that your shortcakes and brownies are described as “moist,” and shortbread cookies described as “crisp” because my forays into LC baking haven’t given me consistent results. Thx also for explicit recipe instructions.
Question though, on your recipes I see you add “vinegar.” Do you prefer distilled white or apple vinegar?
Thanks, and I look forward to more of your recipes!
Kim says
Hi Patti. Thanks so much for taking the time to say “hello”. Yes, aren’t we lucky to have such wonderful low carb ingredients available, like nut flours, that result in moist baked goods! I agree – crispy cookies are impossible in low carb recipes, so I sweetened a cracker recipe. Is it the same buttery texture as a traditional cookie? No. But, it is crispy and not cakey. I’m glad you find the recipes explicit as I strive to be as clear as possible. As far as the vinegar, I use white distilled so that it doesn’t add any off flavors. Such a great question! Have a nice week. -Kim
Michelle @ Modern Acupuncture says
These look so delicious! Holy moly! You are completely right, these would be killer as a base for ice cream sundaes 🙂 And thank you for teaching me about baking without grains each time I read your blog! I’m understanding it more and more with each post!
Kim says
Thanks, Michelle. I’m glad you are finding my posts informative! I think this is one of the nicest comments I’ve received.

Gingi says
HOLY COW, these look delicious!! I want to have!!!!! <3 – http://www.domesticgeekgirl.com
Kim says
Thanks, Gingi! They didn’t last too long… Luckily, they are easy to make.
-Kim
Gingi says
Seriously wishing I had all the ingredients on hand to make some right now… *pout*
Kim says
Yeah, unless you are low carb, you don’t have the ingredients around. But, sugar could be subbed for the erythritol – just wouldn’t be low carb. Thanks for stopping by again. -Kim
