For the chocolate lover! This chocolate cinnamon brownie is the ultimate ketogenic dessert and it’s so simple to make. A lot of brownies can end up a bit dry, but not this one! This low-carb brownie is slightly crumbly, as a good brownie should be, but also surprisingly fluffy. It’s not too heavy so you don’t feel like you’ve over done it by having a slice… or two!

As simple as mix all the ingredients together and into the oven it goes. Make sure you don’t over bake it. You want it slightly soft when you take it out of the oven because the skillet retains the heat so the keto brownie will continue cooking once out of the oven.

I made a large skillet which serves 8 but simply halve the quantities for a smaller 6-inch skillet which serves 4.

Bookmark this one, you’ll want to come back to it again soon!

Wow!  I think this has become one of my favorite sites!  I have tried 3 new dishes and they all turned out beautifully!  BUT ... this dish rocked!  Next time, (and there will be a next) I will increase the sugar by a bit and maybe not have such a high percentage of dark chocolate.  For my non-Keto friends, I served this with ice cream and caramel sauce.  My DH and I had whipped cream and a smidge of the caramel sauce!   This went over quite well!  Thanks and much appreciated!!!  I have been having such a chocolate itch and this dessert certainly scratched the spot!  Kudos on a great recipe!!!

Thank you Patti, I'm glad you enjoyed! You could use sugar-free milk chocolate chips like Lily's if you can find it (Amazon) 😊

I made this last weekend. It was awesome!!! better taste than other normal brownies~
I don't cook very much but this recipe made me laugh out loud for pride~ Thank you~!!

Thank you so much, Dylan, you made my day!!

How many large eggs can I use?

Hi Leah, based on the grams/ounces per large vs medium egg, you'd need to use 3 and 1/2 eggs. I think it's safe to use even 4 large eggs - it should still work well.

I was wondering if there were a suitable alternative to the almond flour.  If so, proper amount to use???  Thank you in advance...  my sweet tooth and I thank you!!!!!  😊

You could use coconut flour but the effect will be more crumbly. This is just a general conversion so it may not work without some tweaking: Use 1/3 cup of coconut flour instead of the 1 cup of almond flour, add one more egg and optionally if too thick you can add some almond milk. I hope this helps!
