This coffee mug cake makes the perfect single serving treat that takes less than a minute to make. It’s fluffy, moist, and topped with an easy streusel.
I’m all about healthy single-serving desserts, especially if they are quick and easy. Mug cakes are one of my favorites, like a protein mug cake, almond flour mug cake, and keto mug cake.
After sampling the delicious classic coffee cake from Starbucks, I wanted to recreate it and give it a single-serving treatment.

Why you’ll love this coffee mug cake recipe
- Perfect texture. Fluffy on the inside, tender on the outside, and topped with a delicious streusel topping. It tastes of cinnamon and vanilla and was instantly one of my favorites!
- Healthier. It’s made with grain-free flours and uses just a little maple syrup to sweeten it.
- Quick and easy. This one takes seconds to prep and just a minute in the microwave to cook.
- Single serving dessert. This is the kind of dessert you make when you crave coffee cake but don’t want to put in the effort to make a full recipe!
Ingredients needed
for the mug cake
- Almond flour– Blanched almond flour is best, not almond meal. The blanched variety yields a fluffier and lighter cake.
- Coconut flour– Gives the mug cake the cakey texture, and with no coconut flavor.
- Baking powder– Gives the mug cake some rise and fluffiness.
- Maple syrup– Adds sweetness while also keeping the middle of the cake moist and fluffy. Honey or agave nectar work.
- Cinnamon– A must for the traditional coffee cake flavor!
- Egg– Room temperature eggs.
- Milk of choice– Any milk can be used. I used unsweetened almond milk.
For the Streusel topping
- Almond flour– Again, try to use blanched almond flour.
- Sweetener of choice– I like brown sugar or coconut sugar.
- Almond butter– Gives a buttery crumble topping, minus the butter or oil. Peanut butter or cashew butter also work.
- Cinnamon– Adds cinnamon flavor.
- Milk– To mix everything together to make the crumble.
- Powdered sugar– Optional, but if you like a glaze.
How do you make a coffee mug cake?
- Prep. Lightly grease a small, microwave-safe bowl or ramekin.
- Make the batter. In a small bowl, add your dry ingredients and stir well. Add your wet ingredients, and mix until a smooth batter remains. If the batter is too thick, add extra milk.
- Make the streusel. In a small bowl, add your streusel ingredients and mix until combined.
- Microwave the mug cake. Transfer the cake batter into a mug and spoon the streusel topping over it and microwave for 1-2 minutes or until cooked. Allow cooling for 1-2 minutes before enjoying!
Tips to make the best coffee cake mug cake
- Microwaves differ based on make and model. Start with microwaving it at one minute, and if it is not cooked, continue microwaving it in 20-second spurts until it is done.
- Use a microwave-safe cereal bowl or shallow container instead of a mug. This will ensure the cake is fully cooked through.
- Do not omit the coconut flour or try to substitute it. It is key to include it to ensure the mug cake is fluffy and tender on the outside.
- As all coconut flour brands differ, you may need more than half a cup of milk (the suggested amount). Continue adding more milk to the batter until it is smooth and thick.
- To reduce the fat and calories, you can use an egg white instead of a whole egg.
Recommended tools to make this recipe

Can I use coconut flour instead of almond flour?
Wow really need to try this recipe, I am so much coffee addicted. Really nice.
Wow really need to try this recipe, I am so much coffee addicted.
This mug cake is delicious!! It has an great cinnamony taste and I love the almond butter streusel! I put it on all of my healthy mug cakes now, and it brings them all to a whole new level of amazing!
I got in right away when I seen the mug coffee cake. Quit the make up real easy and it was a nice change instead of just eggs or fajitas I got to eat good old coffee cake with my coffee. That was great. Good job on your ingredients ratio.
Great little Keto coffee cake!! I added 1/2 Tbs. Ground Flax seed for fiber and 2 Tbs. Chopped Walnuts. Might add a little more cinnamon and sweetener next time, just my preference. I’m very happy to find this recipe! Definitely will make for breakfast frequently!
I seriously can’t believe how good this is! Based on the ingredients I didn’t think I was going to be blown away. Cake tastes moist and rich even without butter or oil somehow. Crumb is amazing on it. One of my new regulars in my rotation of treats.
This is a lovely recipe. I have an almond allergy, so I substituted tigernut for the almond flour and walnut butter for the almond butter and it turned out amazingly. Thank you for the great recipe!
Sorry forgot to add the recipe rating!
We recently got a microwave and have been trying all sorts of mug cake recipes but this is the best I’ve tried so far by far – 5 stars from me!
I really liked this recipe. It was sweet and extremely delicious. The topping was really good as well. I highly recommend this. It was also super simple to make.
Every time I make a mug cake with egg, I always regret it. It always comes out…eggy. Yet I keep trying. : / I unfortunately didn’t like the taste of this either and didn’t finish it.
Just a helpful comment, though: For the topping, in the list of ingredients, mention “optional” or something similar next to the milk. I poured a Tbsp of milk in, assuming all the streusel ingredients were required. THEN I read the next step which mentioned only adding in a splash if desired. So my streusel was definitely liquidy and not actually a streusel.
Delish! A bit big for an average ramekin. Use a big mug.
This mug cake is delicious! Thank you so much for the recipe! Definitely worth the time in the oven.
honestly this is a pretty great mug cake. i make a lot of mug cakes so i am qualified to say so. the topping was my favourite part because almond butter tastes amazing – next time i’ll layer it in the middle of the mug cake as well as the top, half and half so i get it in every bite 🙂
I love the mug in the video! Where can I buy it? Thanks!
It was bought on some travels sorry!
Thank you for sharing your creations!
For this recipe, what size mugs would you recommend?
Thank you so much!
6-8 ounce.
Looks so delicious! I love how easy is is to make!
Thank you for this amazing recipe! I had it for dinner with keto cream cheese frosting instead of the crumble and just loved it!
That sounds like the perfect dinner- YUM!!!!
Can you tell me what the carb, fat, protein and cholesterol content would be for this Coffee Cake?
Hi there! Sure thing- if you go to myfitnesspal and add in all the ingredients, it will give you a full breakdown 🙂
Allergic to almonds and oats, and gluten, what flour should I use? Really want to make this.
typical of someone with a raging sweet craving, I misread the recipe and used vegan butter not almond butter in the streusel topping, so I’ve got some strange frosting/cake batter stuff on the top – still takes good though!
Fantastic- Cheers, Carys!
What is the nutritional breakdown for keto
Not sure, feel free to calculate it using an online calculator.
Hi ! Can I use oat flour instead of almond / coconut flour ? I am in a calorie – restricted diet abs those are off limits for me at this time. Thanks
Hi you can, but it will be more dense- Use 1/4 cup of oat flour overall and reduce liquids.
Let me tell you something. I have made at least half the recipes on your site and I frickin LOVE every single one of them. I am a body building(bikini division) and I’m all about the healthy, low sugar, low carb, low cal snacks that satisfy the sweet tooth. And damn these recipes deliver! Even my husband (who is NOT a fan of healthy foods or protein powder) is crazy about these. You KICK ASS!!!
You have made my night, Sari- Thank you SO much 🙂
I’m confused about the amount of almond milk. How much do we add?
Hi Risti, start with a tablespoon at a time and continue adding, until a thick batter is formed 🙂
Thanks!
How much coffee do you put in your cake,and what kind. You haven’t put anything about coffee.
Hi Susan- A classic coffee cake traditionally doesn’t have coffee in it, rather to be enjoyed with coffee. 🙂
I am confused, why is there no coffee in the coffee cake?
Hi Nikki- Traditional coffee cakes don’t actually contain coffee- The name stems from having it WITH a coffee 🙂 Hope that helps!
I know this defeats the purpose of your healthy version, but…will this same recipe work with all purpose flour and regular milk?
Hi Stephanie! No worries, and all purpose and regular milk are totally part of a healthy diet 🙂
It will definitely work 🙂
I made these for my siblings with oat flour and stevia and they loved it! I topped them with homemade carmel sauce. I love that you have so many gluten and sugar free recipes. It makers it much easier to be on such a diet. They are so easy and yummy! Thanks!
Ahhh! I just stumbled upon your site randomly and it’s so awesome. I’ve honestly been drooling over your recipes for about 10 minutes now. Keep up the good work dude! 🙂
YES! 😀 Thanks so much, Katerina!
Oh this looks sooo good Arman! I love any cake that I can make in one minute lol
You and me both 🙂
I’ll skip the coffee and just take one of these coffee cakes. How about trading it for a slice of my mum’s homemade eggnog cake ;)?
mmm that sounds delicious!
If I could get away with it, I would probably just eat streusel topping on it’s own and scrap whatever was under it. Love.that.stuff. And I’ll have my coffee cake with coffee… duh.
Seriously, struessel topping = LIFE
So, we actually can use an egg white instead of the whole egg! I love that! I wonder if I could do that for all your mugcake recipes, could I?
You could try!
This looks like a great college dorm dessert/snack! It looks even better than the real deal!
Thanks so much Cassie 🙂
Woah, man this looks SO GOOD. 🙂 It’s not breakfast time yet, but I may just have to make this for tomorrow’s breakfast. O_O And 1 minute in the microwave? You can’t beat that!
Please do, it’s delicious!
This sounds so good! I’ve actually never had the coffeecake from Starbucks but this looks even better than the one I’ve seen there!
Thanks Liz!
Wait, does coffee cake not have any coffee in it? Gah I must sounds so lame but coffee cake in the UK always has coffee in it! Not that this needs it, it sounds amazing and the idea of having the perfect cake to go with coffee sounds perfect!
Then again most Brits are obsessed with tea… And we do have tea cakes… That are more like English muffins than cake… We sure like to confuse people!
I was totally in the same boat- It’s designed to enjoy with coffee! 🙂
This looks amazing! I want to try it like now!!
Thanks Taylor!
No worries man, bring on the Starbucks (But wayyyyyy healthier and better) recipes!! All about it! 🙂
🙂 Thanks so much, Cailee!
Don’t fight it. Just embrace it and let the Starbucks fetish lull you!
Coffee with….. anything I guess. As long as coffee is involved I am all set 😉
You said it best!
I don’t think I have ever gotten a sweet treat at Starbucks, but I would be all over this coffee cake! No doubt your version is by far tastier
Thanks so much, Heather- I hope so 🙂
Well who needs Starbucks when we have your blog?!! 🙂 Lazy days do prevail sometimes though. But seriously, you are going to do me in with all this deliciousness! Wait, I forgot this is healthy…I’ll take two!
You said it- you CAN have two 😀
I am looking for an amazing pumpkin custard that is paleo.. (that I can eat instead of pumpkin pie) Do you have any recipes of this kind? I love your ideas, you are so creative. Thank you so much.
I have a pumpkin cookie dough which I love- It’s not custard like in terms of consistency, but is like pumpkin pie filling 🙂
Thanks to you Arman, I never have to spend $$ at Starbucks 🙂 I like my coffee best with a scone. I am addicted to them recently (as long as they have ‘chips’ in them, chocolate, cinnamon, white chocolate…) I like using ramikins for my microwaveable creations. Most of my mugs are too big for these cakes and they make the cake look like it’s for a baby
I use a large mug actually- Like the one linked. They are too small otherwise 🙂
Nommy Nommy Nommy, this is totally love in my tummy! UNTIL IT GIVES ME A STOMACH ACHE AND HIVES – ahem, almonds! LOL!
LOL! My poor g spot.
The only Starbucks cake/dessert I appreciate is their Nutella-stuffed cookies. Have you tried one? Do they even sell them there? Please recreate that!!! They are addictive.
of course they don’t sell it here gaaaaah!
You’ve done it again! Gorgeous mug cake Arman, and oh for that streusel topping!!! And I haven’t had the Starbucks version yet, so may need to sample that also!
Haha, I mean, it totally counts as quality control!
I love my coffee with…silence. Just me and a cup of coffee. Preferably outside on the back patio.
that sounds so blissful!
You’re totally obsessed with Starbucks, but I don’t mind because I kind of am too. I do love a good coffee cake! Our on-campus coffee shop only serves the Starbucks coffee, so all of the baked goodies are made in-house. They just created a whole grain croissant that’s possibly one of the best things I’ve ever had, so I’ve been having my Americano with that lately.
Okay, so- I totally ordered an Americano and I swear the brew was stronger? I did, however, also see Oprah’s drink on the menu too lol!
I might just skip the cake and eat all the streusel topping. 🙂
I approve!
Coffee cake is one of my all-time favorites! I surprisingly haven’t tried the Starbucks version, but I’ll gladly nom-nom this 1-minute version anytime. And Starbucks in the airport is the best thing ever!! (In fact, it’s the only time I ever get Starbucks.) Also, have you noticed that rediculous outrage over Starbuck’s holiday cups this year? Talk about a #FirstWorldProblem!
LOL. It’s been popping up over my social media but it confuses me….I’ll stay oblivious!
Dear Arman, You always surprise me! This 1 minute coffee cake sounds wonderful my friend! Take care, Catherine
Thanks so much, Catherine! 🙂
I am totally in favor of your Starbucks fetish! 😉 As long as it keeps bringing tasty recipes like this…fetish on, friend!
Thanks Kaila!
This looks delicious, quick and easy! Yum!
They sure are- Thank you! 🙂
nothing can beat a freshly made coffee cake with streusel, streusel is a must! I love my coffee with oatmeal!
Yum! That sounds great.
Yummy! Do you know how shocked I was to find out that coffee cake doesn’t taste like coffee? At first I was disappointed, but then I realized it was another excuse to drink coffee. I’ll take it!
YES!!!! I was so excited because I was scared of the caffeine overload!
I love my coffee with…air. It is the only thing that is also necessary.
Hahaha amen!
I am SO hungry right now and these sinful pictures aren’t helping at all – this is 100% my post-work treat today!
YES! Thanks so much, Margaux!
Multiplying the topping by 4 sounds about right! Love my coffee cake 🙂
It’s so good!
