Easy and Delicious Keto Coffee Cake

This Keto Coffee Cake is super soft, buttery, moist, flavorful, and cinnamon-y! It is the perfect breakfast treat to go with your morning coffee.

Unlike most other coffee cake recipes, we have not only included a delicious cinnamon crumble on top of this cake, but also in the middle! Yes, TWO LAYERS of yummy cinnamon is as delicious as it sounds! You could even add some almonds or pecans to the recipe if you are feeling a little nutty!

Another thing that makes this recipe so great is the addition of sour cream to the batter, which makes this cake exceptionally soft and moist without affecting the tase.

Instead of being dry and crumbly like some coffee cakes tend to be, this keto coffee cake is rich and very moist. If you prefer a more dense cake though, feel free to only use 1/2 cup of sour cream instead of an entire cup.

It’s no secret: we love cinnamon! Some of our other favorite recipes using cinnamon are our Keto Cinnamon Pretzels  and our Thick and Soft Keto Snickerdoodle Cookies. If you are a cinnamon lover like me, you will love these recipes as well.

Another thing we love about this keto coffee cake recipe is that it stores in the fridge extremely well.

You can store your leftover keto coffee cake in the fridge for up to a week! I like to microwave a piece each morning and eat it while I drink my morning coffee. If you’re a meal prepper and want to take care of breakfast for a week, this keto coffee cake is a must!


Coffee In Coffee Cake?

So, moment of honestly here. For a good part of my life, I assumed that “coffee cake” must be made with coffee. Makes sense, I thought.

But that was before I was a coffee drinker and when I thought “coffee cake” was an old person food.

Now I know that, despite the name, there is no coffee in this cake. Instead, coffee cake got its name because, you guessed it, it is enjoyed best with a cup of coffee in the morning.

I think it’s called “coffee cake” because “breakfast cake” sounds like something a toddler would invest as an excuse to have birthday cake for breakfast. Trust me though, this cake is good at any time of day!


Our keto coffee cake is great with a cup of coffee in the morning, but it’s also delicious with a cold glass of almond milk, a cup of hot tea, or pretty much any other delicious beverage at any time of day! You can’t go wrong with this keto coffee cake.

Keto Coffee Cake Sweetened With Monkfruit

This keto coffee cake, just like all of our keto desserts, is sweetened with Lakanto Monkfruit, which is our absolute favorite keto friendly sweetener. Monkfruit is zero glycemic, completely natural, carb free, has a 1:1 ratio to sugar which makes converting traditional recipes a breeze, and most importantly, it tastes absolutely amazing which makes it the perfect sweetener in my book!

Unlike many of the other keto friendly sweeteners on the market, with Monkfruit, there is no nasty aftertaste, and of all the keto sweeteners, it truly tastes the best.

If you have never tried Monkfruit, or if you just need to restock, you can purchase some through Lakanto’s website. If you shop their website, use our code, “BUTTERTOGETHER” at checkout and you will save 20% off of your entire purchase! This coupon applies to all products on their site as well, and not just Monkfruit. View all of Lakantos amazing keto products, including brownie mix, cookie mix, spreads and more HERE!

  • Mo Grener

    Best coffee cake!!! I love it!!! I think the monk fruit sweetner products are the best- better than stevia! I’m going to try your fudge next! Thank you!

  • Riverlandlass

    Fantastic cake, I only used the crumble on the top, and served it with whipped cream…Yum!
    Will definitely be making this on a regular basis.
    Thank you for this wonderful recipe.

  • Jacqueline Meyers

    Started Keto a month ago and since my husband has not I am on the look out for things we can both eat. This coffee cake is the BEST. Not only does my picky eater husband like it but asked for seconds before I even finished my first piece. Wonderful recipe and so easy to make

    • Loretta

      The Nutritional information gives the “Net Carbs” but what would the total carbs be?

      • Kasey

        Total carbs would be 8, and we have added that to the recipe card. Thank you!

  • Dusty

    Do you absolutely need to use the xanthan gum? I’ve only done keto a little over a month and haven’t had the chance to get any yet.

    • Kasey

      If you omit the xantham gum, it will affect the stability of the cake. You can always try it, but we are not sure how it will turn out.

    • Jessi

      @Kasey, hi! Could you sub out anything for the xantham gum?

      • Kasey

        You can always omit it or use ground flax seed or psyllium husk powder. Just look up excahnge ratios.

  • Linda Ebert

    Made this tonight -YUMMY !!! My husband says it is a definite keeper! Reminds me of a family coffee cake recipe (not Keto) that our family makes!! I will definitely be making this again!

  • Van

    You suggest using either a 9×9 baking dish or a 9×13 casserole dish. To me, that’s quite a difference in size and must surely effect thickness, baking time and serving size. Which size of baking dish would you say gives the most desirable outcome for this coffee cake?

  • Allie

    I used chia seeds 1:1 ratio instead of xanthan gum, and I swirled in the crumble rather than layering . Came out perfect, Thank You!

    • Kasey

      We are so glad you enjoyed it. Thanks for letting us know how your alterations worked out!

  • Teri Satterwhite

    I only have a 1/2 cup of Sour cream at home, do you think the other 1/2 i can sub with plain yogurt?

    • Kasey

      Yes! Full fat plain greek yogurt is able to be subbed. It might affect the nutrients, altering your macros, but it is worth a shot. Let us know how it goes!

  • Jami

    This has an excellent taste but fell apart. Was not cake like. What did I do wrong?

    • Kasey

      I am sorry that happened to you! I am not sure why it would do that. We have not had that experience before with this recipe! Is it possible that you might have accidentally left out a binder or mismeasured?

  • Lisa

    I just made this and it was perfect! Very similar to the coffee cake I’ve been buying at Starbucks for years. Even my husband, who is not keto, tasted it and said he will eat some tomorrow with his coffee. Thank you so much!

  • Maria

    Have you ever halved the recipe? If so how long would I bake for?

    • Kasey

      We have not tried that. I would start at 25 minutes, check with a toothpick, and keep an eye on it. Best of luck!

  • Titi Ricafort

    First time ever keto coffee cake as I needed to make changes to my diet. Was not hard to make and using almond flour made a difference in both texture and taste. It was great!!

  • Jaye Berry

    I made it this morning and the center never got done, honestly i think i baked it for 55-60 minutes. I out it in a aluminum round pan because i wanted to slice it like a pie. What did i do wrong. I know i used the right amount of ingredients. Unfortunately I had to throw it out

    • Kasey

      The only reason we can think of, if all the ingredients were correct, is the pan size. We are so sorry you had this experience!


    Someone replied unsalted butter but the recipe does not state that

  • Celeste Gober

    It sounds yummy, but I can’t use Erythritol ( it bothers my stomach, with lots of bathroom trips) & it’s in the Monk fruit that you use. But I have pure powdered Monk fruit, as well as Stevia. Can you help me with the best amount of the monk fruit / or Stevia to use for conversion in your coffee cake recipe… thanks for your help.

    • Kasey

      Just use the same amount! Hope you enjoy!

      • Chrissy Fonseca

        I dont like almond flour. I use coconut flour. Have u ever tried it with this as a sub? I heard you should use 1/3 the amount of coconut flour. To the amount of almond. Any one know anything other advice?

  • Carol Lepardo

    So, so good! I used an 8×8 dish. Only did crumble on top. Baked about 45 mins. Didn’t have baking soda so left it out. Didn’t have unsalted butter so used salted. Loved, loved, loved it. Came out perfect. Can you freeze the left overs? Afraid to leave in the refrigerator…lol

    • Kasey

      Thank you for trying it! We are so glad you enjoyed it. Yes, you can freeze it!

    • Jared Freedman

      How long does it last in the fridge? Can it sit out at room temperature for a couple days?

      • Kasey

        It should last a few days on the counter and about a week in the refrigerator. Enjoy!

  • Erika

    Absolutely LOVE this recipe!!

  • Elizabeth

    This has become our favorite, go to coffee cake recipe! I made a couple tiny alterations to our family taste. We only ever have salted butter, so I leave out the salt in the crumble. I also upped the sweetener from ¼cup to 1/3 cup in the crumb, since we like it a tiny bit sweeter. It is amazing!
    I have made a ton of variations and all come out great!

    Pumpkin spice: sub 1/2 of the sour cream for pumpkin puree and pumpkin spice in place of the nutmeg/ cinnamon

    Lemon poppyseed: leave out nutmeg/ cinnamon. Add in 1-2 tsp lemon extract and 1 Tbs poppyseed to the cake. Add 1/2 tsp molasses to the crumb along with another 1/2 tsp lemon extract.

    Chocolate chocolate chip: leave out nutmeg/cinnamon. Add in 1/2 cup sugar free chocolate chips to the cake and 1-2 Tbs cocoa pwd to the crumb.

    Blueberry: add in 1/2 cup fresh berries to the cake. An additional 1 tsp of lemon extract to the cake reallysets it off!

  • Sylvanna

    I love this recipe.I want to take and make small it portions to gift to friends. I bought small aluminum tins 3×5..any tips? Or am I over thinking it? I was just gonna make a full recipe and evenly divide among a few tins.

    • Kasey

      That should work just fine! Just remember to adjust the cook time accordingly. I hope they enjoy!

    • Sylvanna

      @Kasey, awesome Thank you! Should I keep the same temp but less time?

  • Jane

    Can you use coconut flour instead of almond flour? If so, how much? Thanks!

    • Kasey

      Yes! You would just use 1/4 cup of coconut flour for every cup of flour called for in the recipe. Coconut flour is more absorbent, so you may want to add extra eggs and liquid. Enjoy!

  • Melissa

    This is one of my favorite recipes for coffee cake,but instead of cake I make jumbo muffins. Makes a dozen easily. Put in freezer bag and put in freezer and grab one on my way out the door for work.. DELICIOUS!!!

    • Kasey

      What a great idea!?! Thanks for sharing!

    • Amy Polka

      @Melissa, I’m doing this now! They smell amazing! How long did you cook the muffins?
