Sometimes, we just want a taste of something sweet to satisfy our cravings or to pair with our morning cup of coffee. That’s where my single-serve coffee cake mug cake comes in handy!
It’s made with a handful of pantry staples and, of course, a healthy dose of cinnamon. A minute of mixing and a minute in the microwave, and you’re rewarded with THE perfect mug cake for cinnamon and coffee cake lovers.
Why I love this recipe
- Wholesome. It’s made with almond and coconut flour, meaning you don’t have to stress about heat treating all purpose flour aka it’s gluten-free.
- Quick and satisfying. 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.
- Easy to make. It’s even easier than my vegan coffee cake recipe!
Key ingredients
- Almond flour. I recommend blanched almond flour over almond meal, as the blanched variety is lighter and makes for a fluffier cake.
- Coconut flour. Gives the mug cake a cakey texture.
- Baking powder. Helps the cake rise and become fluffy.
- 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! I’m a fan of Saigon cinnamon as it has the most authentic cinnamon flavor.
- Vanilla extract. For flavor.
- Egg. Ideally, room temperature eggs are preferred.
- Milk. I used unsweetened almond milk, but dairy milk works.
For the streusel topping:
- Almond flour. Again, try to use blanched almond flour.
- Sugar. I like brown sugar for the topping, though any sugar works.
- Almond butter. Gives a buttery crumble topping minus the melted butter or oil.
- Cinnamon. For flavor.
- Milk. To mix.
- Powdered sugar. To mix with water to make a glaze.
How to make a coffee mug cake
I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.
Step 1- Mix. Combine the dry ingredients in a small bowl. In a separate bowl, whisk the wet ingredients. Add the dry to the wet and mix until smooth.
Step 2- Make the topping. Combine the almond flour, cinnamon, and sugar. Stir in the almond butter until it’s thick and crumbly.
Step 3- Microwave. Grease a microwave-safe mug and pour the cake batter into it. Sprinkle the topping and microwave until fully cooked.
Step 4- Glaze. Whisk the powdered sugar with water and drizzle over the top.
Arman’s recipe tips
- Cut the calories. Use 3 tablespoons of egg whites instead of a whole egg.
- Adjust the consistency. 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.
- Microwave in intervals. Your cake may need more or less time, depending on the wattage of your microwave. I suggest heating it in 20-second intervals, checking between each, until it’s firm around the edges but still slightly soft in the center.
Frequently asked questions
Yes! If you’d rather make this in the oven, replace the microwave-safe bowl with an oven-safe ramekin or similar. Bake at 180C/350F for 10-12 minutes or until a skewer comes out clean.

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 🙂
