A soft, homemade, easy and single serving coffee mug cake!
Coffee Cake In A Mug
This coffee mug cake comes complete with crumbly streusel topping in each little bite.
By now, I think all of my girl friends–and some of the guys too–are on Pinterest. We were talking about the site a few days ago, and one of my friends mentioned a “coffee cake in a mug” pin that taunted her every time she logged into her account.
Finally she wrote down the recipe with the intent of trying it at home, but then was horrified to learn one mug contained 720 calories and an entire day’s worth of saturated fat!

How can they fit so much fat into a single mug?!
So I came up with a healthier version for her.
You could quadruple the following recipe and it would still be healthier than eating one of the frankenmuffins from Pinterest.

I think my friend approves of this recipe.
She’s made it four times already and says I’m her new favorite person in the world.
Apparently my face is now pinned to her “Dream Wedding” Pinterest board, under the title “dream wedding caterer.”
Not sure how I feel about this…

To answer a question that a bunch of people have been asking:
Coffee cakes traditionally do not have actual coffee in the ingredients. They are so named because they’re seen as “a cake that goes well with coffee.”
If you want to add a sprinkle of instant coffee to this cake batter, feel free!
Or you can serve it the traditional way – with coffee, such as this Frappuccino Recipe or the youtube-favorite Whipped Coffee Recipe.

Coffee Mug Cake
Ingredients
- 3 tbsp spelt, white, oat, or almond flour
- 1/4 tsp baking powder
- 1/16 tsp salt
- pinch uncut stevia OR 1 tbsp sugar
- 1 tbsp + 2 tsp water, or 1 egg or flax egg if using almond flour
- 2 tsp oil or buttery spread – or applesauce
- 1/4 tsp pure vanilla extract
For The Streusel
- (If you like a lot of streusel feel free to double all ingredients below)
- 1/8 tsp cinnamon
- 1 1/4 tsp sucanat or brown sugar, or keto sweetener
- 1/4 to 1/2 tsp oil or butter, or applesauce for low-fat
- tiny pinch salt
- 2 pecan or walnut halves
Instructions
- I prefer the oil or buttery spread, but that’s simply because I’m not a fan of fat-free baked goods. If using an oven, preheat to 330 F. Combine batter dry ingredients and mix well. Add wet and mix until just mixed. In a tiny bowl, combine all streusel ingredients. Fill a greased muffin tin 1/2 way with the batter (or use a ramekin or mug, if using the microwave). Sprinkle on two-thirds of the streusel, then spoon the remaining batter on top. Finally, sprinkle on the rest of the streusel. Cook 12-13 minutes in the oven, or around 1 minute in the microwave. Microwave times will vary, depending on microwave wattage.View Nutrition Facts

Loved this recipe! Thanks for sharing!
Where is the coffee in the recipe?
I made it but they didn’t fluff up… i live at high altitude so should I cut back the baking powder next time?
To make this coffee cake, as in coffee flavoured, how much coffee would you add?
Looks fabulous and I love the option of just making one portion.

Katie a lot of your recipes say uncut stevia. I use the liquid stevia and have a tough time converting. Do you know how many drops would work when you say a pinch of uncut?
This looks amazing!
And I’d rather look at pictures of cake than weddings. 🙂
If course, I’m already married…
This was delicious, Katie! Just made it. Still warm. =) Fabulous! A new keeper.
Man, this looks yummo! 🙂
First of all, when i tried this i didn’t look anywhere as pretty as the photos but it was still delicious and perfectly fluffy. When i made this my second time i doubled the whole recipe because it made a very small portion. I also added instant coffee granules which gave it a nice coffee taste.
Am i being stupid…
where’s the coffee??
This looks scrumptous! I’ll take like 5 of these with my triple shot espresso! 😀
I love these mug cakes. I make this one in the morning and it is so delicious. Thank you so much for coming up with a healthy version.
Hi Katie, fantastic recipe! So yum. Can this be made into a full cake?
I’ve never tried, but I do have a different coffee cake recipe if you’d prefer: https://lett-trim.today/2013/03/01/cream-cheese-stuffed-coffee-cake/%3C/a%3E%3C/p%3E
These muffins were AMAZING!! I absolutely loved them (I made multiple:) thank you so much for sharing
Love this recipe! I was so surprised! Only 3 points weight watchers, thank you!
I had never successfully microwaved cake before, but this was delicious. It seemed a little wet when I took it out, but they get awful when overcooked, so I pulled it anyway. The texture is really nice with no egg. It’s kinda flat, but my mug is super wide. I might throw one together tonight to have in the morning.
