How to Make the Best Gluten-Free Coffee Cake
There are a few steps to making this wonderful Low Carb coffee cake, but it's most definitely worth the effort! Let's start by preheating your oven to 325F.
Add the almond flour, oat fiber, baking powder and salt to a bowl and whisk them to combine.
In a separate bowl, mix together the eggs, sour cream, heavy cream, swerve and vanilla using a hand mixer. Then, add in the dry ingredients and mix just until combined. You don't want to over-mix the batter.
Pour all the batter, minus ⅓ cup, into a 9″x 9″ glass or ceramic baking dish lined with parchment paper (for easy removal) and spread out evenly. You can use an offset spatula to make it easier.
Take the reserved ⅓ cup of the batter and mix in the cinnamon and 2 teaspoons of Swerve confectioners.
Take the sweet cinnamon mixture and dollop evenly all over the top of the cake. This next step is easy and actually makes it look really pretty!
Using a butter knife, holding it upright, swirl the cinnamon mixture into the cake batter.
How to Make the Crumble Topping
There is something about this topping that is so wonderful! The texture is just spot on, very much like a classic crumble topping, but without all the carbs and sugar! So let's take the almond flour, walnuts, cinnamon, nutmeg and Swerve and add it into a mixing bowl, then mix it together.
Then pour the melted butter over the top and mix until well combined and it comes together. Crumble the topping over the top of the cake, making sure to evenly distribute it.
Then gently press the crumbs into the batter slightly. This will help the topping stick to the coffee cake and not fall off when you cut into it.
Bake for 40-45 minutes or a toothpick, when inserted, comes out clean and the crumb topping is golden. Let it cool down a bit before cutting into it. It doesn't have to completely cool, but letting it to cool a little, allows the topping to firm up a bit.
Mine took exactly 45 minutes. Store leftovers in the fridge for several days or freeze.
How to Make the Best Keto Coffee Cake
Texture is key in making a Low Carb cake recipe. Too many come out dry or with a “diet food texture.” But not your recipes! You are about to know the secret.
Using a mix of both Almond Flour and Oat Fiber will give you that authentic coffee cake texture that you’re looking for. Super fine almond flour works best in any kind of Low Carb or Gluten-Free desserts that don’t use all purpose flour in.
If you don’t have a super fine almond flour, you can certainly use what you have, just be sure to whisk the dry ingredients to break up any lumps.
What is Oat Fiber? Is Oat Fiber Keto?
Oat Fiber is made from grinding the outer husks of oats. How healthy is oat fiber? It's pure insoluble fiber, which doesn't dissolve in water and isn't broken down in the digestive tract, so it has zero net carbs and is perfect for a Keto Diet. It helps give a more traditional texture and that's why I use it so often. Check out all the Keto Oat Fiber Recipes you can make!
What is a Substitute for Oat Fiber?
To get the best results, it's best to use oat fiber if you can. If you're unable to find it, try a combination of psyllium husk powder and coconut flour. Since both are very absorbent, you might have to add more liquid.
What Sweetener is Best for Keto Baking
Swerve Confectioners has the best balance for Low Carb dessert recipes. Brown Swerve is great to use in recipes that would normally use brown sugar. Brown Swerve tastes, smells and feels just like brown sugar! Swerve, really did a great job with their sweeteners!
If you can't get Swerve confectioners or Brown Swerve where you are, you can certainly substitute with another brand that you do have access to. If you can’t get confectioners, no worries, you can grind the granular to a fine powder using a coffee grinder and voila, there you have it! It really is the best sweetener to use in sugar free cake recipes.
Enjoy with a nice piping hot cup of Bulletproof Coffee with MCT Oil! If you like raspberries, you will love this Keto Coffee Cake!

I wish you would sell your cin. rolls, too many steps for me and they look amazing!!!
Keto Cooking Christian
They do take a few extra steps, but they are simply amazing!
Marie
Thank you very much for sharing the recipe of this delicious coffee cake crumble! To be honest, I rarely wrote reviews and all the reviews I wrote were for clothing I purchased online; English is not my first language….But, after eating a slice of this cake as soon as it came out of the oven, I had to write a review. I never had a KETO CAKE THAT TASTE EXACTLY AS AN ALL PURPOSE FLOUR CAKE! Your cake is delightful. I made a little mistake because I did not watch the video, I added 1 Tsp of ground cinnamon to the main cake mix instead to add it only to the 1/3 for the swirling effect. And because of it I don‘t have a clear marble effect BUT the taste and texture of the cake are 10 out of 10! I think the game changer is the Oat Fiber. Again thank you for sharing, stay safe and God bless.
Keto Cooking Christian
This is one of the sweetest reviews! Thank you so much. It absolutely thrills me when I hear that someone loves a recipe of mine as much as you do. You were so kind to take time to review it. God bless you.
Jerry
Excellent moist cake. The only ingredient that I added to the topping mix was some almond flour. I highly recommend this recipe.
Keto Cooking Christian
Thank you so much! I appreciate the awesome rating.
Amirah
Absolutely the best.
I can't believe this is so good and Keto the same time. Super moist and yummy. I used potato fiber ( Living in Germany) that I used for your farmers bread as well. Love it!
Thank you so much!
Keto Cooking Christian
That's wonderful, I'm glad you loved it!
Debbie Case
Well, I just figured it out! No worries!! Looking forward to trying these out! Thanks!
Keto Cooking Christian
Oh good! Let me know if you have other issues! Enjoy!
Debbie Case
Julianne, this looks amazing, and I can’t wait to try it! So do all your recipes! I bought your recipe books for $17, but I can’t seem to get to them. A JavaScript issue, it says. And the bar at the bottom doesn’t come up as you described. What do I do?
Thanks!
Debbie
Jill
I’m a professionally trained pastry chef. I’ve baked regular pastries, as well as gluten free. However, when it comes to baking keto, I can’t seem to figure it out. This is amazing (your recipes are all amazing!!!) The only change that I’ve made is to add more cinnamon. Thanks and look forward to baking more of your recipes.
Keto Cooking Christian
Thanks so much, that's such a wonderful compliment. I'm glad you enjoyed it and more cinnamon sounds great!
Laura
This is AMAZING!!!!! Doesn’t taste keto at all! By far, my favorite keto dessert I’ve had!!!
Keto Cooking Christian
Yay, that's so nice to hear!! I'm happy to you enjoyed it.
Linda
Thank you for this incredibly delicious recipe. I made this today and we both loved it!
I have a question. My batter was like cake batter and not as dense as yours. I’m guessing the way I measured my almond flour was not the same as you. Could you measure out 1 cup of almond flour and weigh it on a digital scale, then reply here so I can adjust my measuring to match? I want to try more of your recipes and this would really help me. Thanks!
Ammara Nisar
This was lovelyyyy. I absolutely love the crunchiness on the top and the soft cake underneath. Thumbs up here cz Im a big cinnamon fan lol. Thank u again for this recipe ♥️
Keto Cooking Christian
Yay, happy to hear you love it! 🙂
xoML
This was fabulous. Mr. Awesome completely approved. Followed the recipe 99%. Substitution: pecans for walnuts because of allergy. Seriously. Super-yum.
Celeste Gober
This sounds delicious. I tried Swerve & it didn’t agree with me, lots of bathroom trips for over a week. I have pure powdered monk fruit, as well as Stevia, both powder & drops. Can you advise me on proper amounts, as far as replacing Swerve with the monk fruit and or Stevia
Keto Cooking Christian
If you use Monk Fruit, it's a 1:1 sub, so no adjusting needed there. I wouldn't recommend using Stevia in this recipe though.
Sherrie Perry
Is there anything I can sub out for the Oat Fiber? I am getting ready to make this and don't have any...I have psyllium husk on hand...
Keto Cooking Christian
You can try using psyllium husk powder, but since I've not tried that before, I can't say for sure how it might turn out.
xoML
Noteworthy: Oat FIBER is its own thing adding bulk, not necessarily binding like the gooey psyllium does. Oat fiber is easily found on Amazon for reasonable prices. It’s very versatile. I encourage the investment.
Karen
Yum!! I have such a sweet tooth, I sprinkled more Confecrioners Stevia on the top after it was baked and it was perfect! I will make this again and again! Thank you so much for a big help on this keto journey!!
Keto Cooking Christian
You are so welcome and I'm glad you liked it!
Sandra
Wow! Wow! Wow! After two years of low-carb baking, I can honestly say this had the best texture of any cake/muffin I've made in all that time. (and it tasted yummy too!) If the oat fiber is the reason, then I highly recommend not using a substitute for it....seriously, as close to "traditional" cake texture as I've had since starting my keto journey.
Keto Cooking Christian
Thanks so much, glad you liked it! The oat fiber plays a huge part in creating that texture, so I agree with you, it's best to use it and not sub it out!
Vickie Worthington
Oh wow! Best coffee cake ever! Thank you so much for your recipes!
Keto Cooking Christian
Yay, so glad you liked it and you're so welcome!
Laura
I made this a few days ago. I followed the recipe exactly. All the flavors are there, but it came out really crumbly. Any thoughts on what may have happened? Would Xanthum gum help?
Steph F
Wanted to vote 5 stars!!
Steph F
Wanted to come back and say this recipe is AMAZING!! I made them into muffins and they were done around 28 minutes! Thank you!
Steph F
I am about to make these today since I have all the ingredients on hand (got Oat Fiber to make some delicious bread this weekend!) If I am making them into muffins, would you say 20 minutes in the oven would be a good time to start checking for doneness?
Keto Cooking Christian
I would say closer to 30 minutes is better. I hope you enjoy it 🙂
Chris
Just made this today for breakfast. It’s beautiful and delicious. I didn’t have the ost fiber either but I did have oat bran so I ground that up fine in my food processor. Worked like a charm. Also didn’t have walnuts but ground sunflower seeds worked just as well.
Thanks for making my morning!
Keto Cooking Christian
Glad you enjoy it! Just be careful, oat bran has many more carbs than oat fiber, which has zero net carbs.
Carrie
This sounds awesome, I’m sitting here thinking I’d like to make it today. I have all the ingredients except the oat fiber, do you think it’s worth making without it?
Keto Cooking Christian
You can try a combination of psyllium husk powder and coconut flour, maybe add a little more liquid if you really need to make it today. But honestly, it's so worth waiting for the oat fiber because it gives the perfect texture to this coffee cake.
Pam
Very tasty. I used inulin instead of oat fiber and it was marvelous! I would add inulin to the crumble and reduce sweetness by a bit in the crumble. Otherwise fab!
Keto Cooking Christian
Glad you enjoyed it!
Andriana
Can you substitute the oat fiber with freekah flour? I can’t find oat fiber anywhere other than online.
Keto Cooking Christian
I'm not familiar with that flour at all, so I can't say for sure how it might turn out. Oat fiber is really different from any flour I've ever used and it's really key in the recipe to give it that texture.
Marsha
Can I use psyllium powder instead of oat fiber
Cheryl Climenhaga
Wondering same
Lucia Marigliano
...erm. I love your recipes Julianne! I've tried lots and they turn out delicious - they really do. So well done you!!!
But...
I being silly I know
...but
where's the coffee?
Keto Cooking Christian
Aww, thanks for your kind words! I'm glad you like the recipes, thanks for stopping by to let me know! As for the coffee, well I drank it of course 😂
Jennifer Dowell
For the cake batter it didnt have a measurement for the nutmeg only for the topping, I used 1/4 teaspoon so i hope it turns out great got 20 mins left in the oven.
Keto Cooking Christian
Hi Jennifer,
There isn't any nutmeg in the cinnamon swirl part, that was a typo, which I've corrected. But, 1/4 teaspoon should be just fine and if anything, will make it taste even better! Sorry for the confusion!
Ayla
This recipe is so good! I have made it a few times and everyone loves it! The last time I made it, I switched out 1/2 teaspoon of vanilla for almond flavoring and I made an icing with swerve confectioners and some heavy whipping cream then drizzled it over the top. It was incredible!! Thank you!
Keto Cooking Christian
Hi Ayla,
What a great idea, that's very creative and I bet it tasted amazing! I love almond extract too, I will have to try that next time I make it! Thanks for the tip 🙂
kimberly b westling
WOW!!! Amazing coffee cake! This is by far the BEST keto cake recipe of any kind I have ever made!! I have wasted so much money on recipes that were awful! Not this one. The cake has a great "cake like" texture and is moist, which most keto cakes are not. My only question is why don't you have a cookbook? Anyone who can formulate a cake recipe like this, has the talent to write their own cookbook. I thank you for sharing this recipe.
Keto Cooking Christian
Hi Kimberly,
What a sweet compliment, thank you so much for your kind words! I'm so glad you enjoyed the coffee cake, it's one of my favorites too! I do hope to write a cookbook one day, hopefully sooner than later 🙂 Thanks again for the great feedback, I appreciate it!
Carole
Is oat fiber the same as oat bran?
Keto Cooking Christian
Hi Carole,
No, it's different from oat bran. Oat bran is the outer layer of an oat, which is just underneath the outer husk. Oat fiber is made from grinding the outer husk of an oat (like psyllium husk powder), rather than the oat itself. Oat fiber is pure insoluble fiber, so there are zero net carbs in it. I hope that helps!
Debbs
Looks lovely, cant wait for the oat fibre to arrive to test it.
Keto Cooking Christian
Hi Debbs,
It's inside the recipe card, little purple button that says "print", just under the picture 🙂
