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

Katie, this looks wonderful! Speaking of weddings, or rather anniversaries, we will be celebrating our 25th this Autumn and I have already been collecting coffee mugs to give as favors along with a Single Serving of Mug Cake. HOWEVER, I think the plan has now changed! This will be way more meaningful! We get up every morning and enjoy a good cup of coffee and some together time before our days get crazy! We pray together and always, always talk! This recipe will lead right into sharing one of our tips for a lasting, loving marriage! Thank you!
We started with a very simple wedding, (the florist didn’t even arrive until after the ceremony, LOL) and a reception that was thrown together, by today’s standards, but we have been so happy together, (even during the very difficult times)! Your spirit is so refreshing and you will reap such wonderful joy if you continue to look at your wedding day with that view! Here’s what I’ve always told my, (now grown) daughters, “A wedding is a DAY, a marriage is a LIFETIME, keep your perspective grounded.”
Thanks for the post!
i just made this as a super quick snack and it has been the only microwaved treat that has not disappointed me! i sub’d almond milk for some of the water and swirled the topping throughout the batter [whilst still saving some for the very top] and it was heavenly. thanks so much katie!
This may be a silly question, but are mugs oven-proof?
I think it depends on the mug, but I don’t honestly know!
Very important question: Are you working on a cookbook? Please say yes, please say yes.
Thanks!
Wow this is tasty! I added a little coconut extract to the batter and for the topping I mixed Sucanat with some Olivio Coconut Spread (a.k.a coconut butter). I was going to top this cake with your cheesecake sauce but it’s perfect as is.
Yum! I just made a quadruple batch of these and ate two before I could stop myself! I used 1/3 whole wheat and 2/3 white cake flour, half and half coconut oil and apple sauce, and half Stevia half sugar in the cake part. I used xylitol in the streusel, and confess to doubling the streusel recipe ( it’s my favourite part of coffee cake!) I baked them in the oven and they rose beautifully, and were nice and light. Thanks soooo much for this delicious recipe!
Yeah, I tried that nasty Pinterest one, and it was the consistency of rubber. Tasted like rubber, too. Never trust a mug cake with a whole egg in it, people!! I will be making this one tomorrow night. You haven’t let me down yet–you’re chocolate mug cake is a constant in this house.
As for your question, my friends have all moved on from wedding talk to BABIES. I have one of those, so I guess I’m in the club.
lol wedding talk is scary enough for me right now!
Although… I kinda like the fact that some of my friends are having babies now. It means I get to buy cute clothes for them and play with them and hold them… and then give them back! 😉
Just made this with applesauce, whole wheat flour, and used the microwave. With the combination of those, I didn’t expect much. But I took a bite, and just stared at it for a couple seconds trying to comprehend how it was so tasty! For the streusel, I made more of a syrup-y consistency, so the cake came out like a moist cinnamon roll. Delicious! Thanks for the recipe, I’m sure I’ll be making plenty more of these bad boys!
I made this for breakfast this morning (with whole wheat flour, in the oven) and it was DELICIOUS!! I’ve made SO many of your recipes, and this is one of my favorites!! You are a GENIUS, Katie!! I can’t wait for your cookbook!!
I also have a question about this recipe. Could I mix it up the night before, refrigerate it, and pop it in the microwave or oven the next morning??
I have finally tried this recipe and have to say they are the best mini-coffee cakes ever! You are truly amazing, Katie. I’ll be making more this weekend.
Awesome Recipe!!! I just made these and they are scrumdidilumpcious…. *LOL* My boyfriend is eating them and drinking coffee…. Thanks!!!!
Hi Katie, I tried twice to make this but I used almond flour and coconut flour. When I put the wet ingredients in there it was thick so I put some more water and it still thick so I put it in the oven and it took over 30 minutes and it was tasty but mushy. Any ideas??

Sorry, I can only vouch for the results if you use the flour listed in the recipe.
i tried making this last night for a friend whose birthday it was – apparently it was really tasty because she said it tasted like an Entenmann’s doughnut!! thanks so much!
Yum! I just made this subbing orange juice for the vanilla and mixing orange zest throughout- just what I needed to get me through an all night finals study sesh 😮
I made this. It came out hard as a rock and I only put it in for 60 seconds ):
I used all the ingredients you said. :c
I made this for my family last week and already they’re having me make it again because we all loved it so much! I used white flour, oven, and applesauce, and none of my family noticed any gumminess. They were probably too distracted with the delicious doubled streusel. 🙂 Thank you, and can’t wait to buy your cookbook!
