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.

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!
