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 saw this recipe this morning, and I promptly made it for breakfast. It was delicious! Since I am a celiac, I made it with a tablespoon of GF oat flour, a tablespoon of sorghum flour and a tablespoon of brown rice flour (really random-I know, but it worked!). I know this is something I will make again :).
I *just* made this. SO GOOD!! Thank you for helping me deal with my PMS in a healthy way!
I just made this in the microwave–and LOVE it!! I’m thinking of adding apple chunks next time…
Oh my goodness! I thought your 1 minute chocolate cake was genius, this goes onto another level of deliciousness Katie! Thank you for sharing.
Tried this recipe and it was amazing and super easy. I added a little extra cinnamon to the dry components. I love cinnamon and adding a little extra to your daily intake is is good for stabilizing blood sugar and lowering bad cholesterol.
Just made the coffee cake in a mug for my kids! They adore it!! I substituted cinnamon applesauce for the sour cream/ yogurt.mainly cause thats all I had.this is great for very small get togethers 😉
Yum! This was perfect–exactly what I needed tonight! And filling, actually. I don’t think I expected that. I have never “baked” anything in the microwave–loved it!
I wanted something sweet so I started surfing the web and found this. It only took me a half hour to decide that I wanted something sweet, find a recipe, make it, eat it and clean up. And it turned out great. I loved it, I doubled the streusel and mixed half in with the batter. Definitely a win!!!
I don’t know if this is a good thing or a bad thing I found this. It is absolutely delicious and super easy to make. I predict I will make this often! 🙂
I just made this and it was SO good. I made the mistake of putting it in too big of a mug and ended up needing to make more batter. I also doubled the streusel before I knew I was going to have to make more batter. I’m pretty sure there was more streusel than cake…and I had to cook it a bit longer but it was still really good. I’ll make it again in a smaller mug and maybe even have the patience for the oven. I honestly didn’t think the texture was too spongy in the microwave but I did use oil.
I made this for breakfast for a friend and I…it is soo yummy! And mine actually looked exactly like the picture! Haha..thanks for the great recipe!!
So good this morning at 4AM, as we were up from jet lag and hungry prior to breakfast- that will be cherry bomb oats! And thank you.
I had to search Pinterest for this recipe, I knew I had seen it before! I’m craving cake right now so will have to try it, but I’m going to use agave syrup….
thank you Katie!
I use a metric system but I didn’t convert it to ml and all – I just literally used the tablespoon that I use at the dining table, mixed everything together and baked it in a muffin cup. It turned out a little like a cookie, albeit a soft cookie. And I noticed that when I mixed the batter, it wasn’t runny – it was literally like cookie dough. That’s not supposed to be the correct way, right? :/
This looks yummy! Would Spenda work? And how about coconut oil? I’m trying to avoid vegetable oils, sugar and margarine. I tried Stevia (I think it was) in Sprouts and didn’t are for it. It was bitter… Or something.
Coconut oil is fine! I have never tried splenda so I can’t say.
Delicious!
I planned my wedding in three weeks. To me, all that was important was that I was marrying the man of my dreams and that all the people I loved was present. I don’t get these people who go to a different country to get married. What’s up with that? It means a lot of people can’t afford to be there on your big day.
