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

I made this this morning and it was absolutely delicious!!
I might be missing it, but I can’t see any coffee in the ingredients?
Confused….
Coffee cake doesn’t usually have coffee ;).
1 minute coffe mug cake. Made almost as stated. Used 2 T. Spelt and 1 T. Tapioca flours. Xylitol for the cake and honey for the streusel. So good! Topping ended up like caramel. Thanks for another hit!
Just found out that Hubbie is wheat sensitive. So instead of using the dry ingredients listed, I substituted it with gluten free pancake mix (only thing I had). Turns out just as yummy as coffee cake with 1 pleased Hubbie! Thank you.
OH MY GOODNESS! I was looking for a little treat tonight and was browsing your single-serving recipes, decided to try this and it was delicious! Exactly what I was looking for )
Delicious! Made the single serving, then went and made two more for my friends.Thanks!
Hi Katie. I love your blog and have been trying and playing with your recipes. I have a blog too and was wondering if I could post the recipes themselves (ingred. instruc. etc.) how I make them and always link back to your blog (either acknowledging inspiration or your exact recipe)?
I don’t want to post instructions and etc. until I get your thumbs up.
Thank you. 🙂

Hi Ashley,
The way you have your post now–with the link to the actual recipe, but with your own photos, is perfect! 🙂
Where is the coffee in this cake? I can’t see anything coffee flavoured in the ingredients list???
Coffee cake is a cake that goes with coffee. There usually isn’t any coffee in coffee cake ;).
I researched healthy muffins because I have been dying for one, and I came upon this. I made it and I have to say that it tasted absolutely no different than the huge caloric ones you buy at the store. It was amazing. I still can’t believe it. I’ll be using your recipes from now on!
This looks so yummy! I’m gluten intolerant, though and I’m having trouble getting this turn out right. I used gluten free all purpose flour and tried making it in a mug and it turned out totally weird. I tried again another day thinking maybe I had measured something wrong. And I baked it in the oven. It was better than the microwave one, but still a little gummy. Not sure what I’m doing wrong or if maybe I need to try another flour.
Unfortunately, I’ve only tried it with the flours listed so I really can’t help :(.
Where does the coffee flavour come from? Should I add dry coffee granules to the mix or some liquid coffee? I really want to make this but I am not a natural baker so have no idea about wet/dry ratios. Please help!

Thank you so much for clearing this up. In Europe coffee cake usually has the flavour of coffee but cake that goes with coffee is a nice idea too. I will try it.
Yummy! I used 2 tbsp of brown rice flour and 1 tbsp chickpea flour
I had to laugh when I read about the contracts that they have their bridesmaid’s sign. In my opinion they should want the bridesmaids all to have broken bones, bad hairstyles and teeth knocked out….it makes the bride look even more gorgeous in comparison! 😉 Why do you think most brides give the bridesmaids the most god awful dresses?

Tried this just now with Bob’s Red Mill GF AP flour & in the microwave. I can’t wait to try it in the oven because I think it will be even better. Thanks for the recipe!
THIS IS AMAZINGGGG!
