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

this looks amazing! What do you have drizzled on the top of it?
As someone who just got married, it is hard not to get caught up in wedding madness! I’ve heard stories of brides making the bridesmaids dye their hair so that nobody has the same hair color as them! How crazy! Aren’t they in your wedding because you love them and want their support?
You can make a really quick icing by just mixing powdered sugar or sugar-free powdered sugar with a few drops milk of choice.
(I think you could just use water for a thinner icing… I used almond milk for the one in the photos)
Have you ever cooked it in the microwave? Its how I make them, but when I open the door… it gets… a little flatter than it looks in the picture. I was wondering if the same happens to you.
This actually made me laugh. I would say mine are a bit flat too when microwaved. 🙂
Yup, it definitely doesn’t look as pretty! That’s the price you pay for convenience!
LOL.Or in my case…impatience. 🙂
Love this recipe!!! I use oat flour and cut back a little on the sugar. It’s perfect! I love your recipes. You are my favorite food blogger. Thank you!
I love what you’re saying about weddings – hasn’t it become the social norm to focus more on the wedding than the actual marriage? After three years of reading books like the Five Love Languages, Personality Plus and Building Your Mate’s Self Esteem; hanging out with couples who have been married for years and are actually happy, and learning as much as possible about building a solid foundation, my honey and I are finally at the planning stage. Honestly, this stage is getting less attention than other struggles in our life that we are going through together.
The divorce rate is over 50%, correct? There’s nothing wrong with wanting to plan out a beautiful wedding, but perhaps we all need to consider what’s going to happen several years down the road when the butterflies flutter away!
Ahhh this looks so good! I love wedding shows and generally all things wedding, but I think being single with a wedding pinterest board is definitely crossing the line… although I’m also not one of those girls who dreams of her wedding and has everything picked out. I figure, how can I imagine my wedding if I don’t have the groom yet!?
Forgot to add – I used spelt flour in mine.
haha your friend sounds adorable! and I looove coffee cake, so I’ll have to give this a try.
can’t touch the wedding thing, haha. sure, I want to get married some day, but I’m more focused on building my relationship than thinking of the perfect “day.” Because it’s just one day out of your whole life with someone, and every day with them should be amazing.
Deeeelish! I’m pretty sure I’m going to love this!
…Watch out- it goes from wedding talk to baby talk REALLY fast! 😉
Katie! I’ve been brainstorming some new single serving recipes to bake up, so this post is PERFECT for me today. I think I’m going to try it with butte rinstead of oil or applesauce – and bake up in the oven. I’ll let you know when I make it and link up from my post. Thanks for another awesome single girl recipe CCK!
Coffee cake is one thing I adore but hate to eat because of the calories! I can’t believe it either, but this recipe looks soo good. Perfect for a post-weekend breakfast!
Oh my gosh! This looks incredible, and easy!
Omg I love coffee cake and this looks delicious! The ingredients are so simple too and happen to be all things that I have on hand! LOVE that!! I can’t believe the recipe your friend found had so many calories- that’s horrifying! And I don’t have a wedding board on Pinterest but I do love all things wedding! I’m obsessed with the tv shows and get my fix from them!
Yummmmm coffee cake.
I do have a wedding page on Pinterest, but its only for those pins that are so crazy cool I think “I want to do that IF I ever get hitched.” I feel weird planning a wedding without the groom….he’s kind of half the party, ya know? His opinions definitely count, so why plan the whole thing alone…when I’m still single?
I wasn’t on Pinterist when I planned my wedding last year. It would have been SUPER USEFUL for keeping all my ideas and vendor websites in one place, but I would keep the board private so my guests would be still be SURPRISED at my fabulous wedding!
So excited to make this! I looooove your easy, quick recipes!
I’m gearing up for my first wedding where I’m not invited simply because I’m family. It’s one of my friends — which is making me freak out because that means that I am of a marrying age suddenly. Which is a very scary thought. lol
Love the mug cake. I’ve made the fattier versions before and love that there is now a better version out there!
Ahhh this looks SO tasty! I really love all of your single-serving recipes. Thanks for another great one!
Oh my goodness! I can’t wait to try it!!! 😀
I think about my future wedding from time to time, but you’re right! It’s all about who’s standing across from you on the altar!
