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

hmmmm just wondering about the pure stevia substitute – Just wanted to check if its 1/3 or 1/2 – maybe a little typo there!
Looks tasty as – I love coffee so can’t wait to try this 🙂
thanks for all your awesome recipes
Nope, that’s 1/32 tsp. It’s if you use pure, UNCUT stevia. If you’re using cut stevia, use 1/2 tsp.
Wow – ok thanks! 🙂
I had never heard of the uncut stuff 🙂
I just made this for my morning tea break here in Sydney and I’m totally in LOVE with it!
Thanks
Katie, is the pure uncut stuff 100% stevia extract? I’ve got a bottle (it is a powder) from Trader Joe’s with the label “100% stevia extract” that I have never used and I always wonder if that is what you are referring to when you mention “uncut” stevia in your recipes? If not, then what is it and where can I find it?
P.S. I wanted to tell you that you look absolutely gorgeous in your mother’s day photo with your mom! 🙂
Katie!!! You’re amazing!!! This is awesome!!! Yum!!!
Have I tooold you latelyyy that I love you? 🙂
Thank you! I loooove coffee cake and can’t wait to try this at home!
Wow! You came up with a perfect recipe that I’ve been looking for before I even knew I was looking for it! This looks amazing & I’ll be making it ASAP.
I just made this in the microwave and it was INCREDIBLE! I love microwave mug cakes, and this is by far the best one I’ve ever tried- and it’s so easy. Thank you so much!
You just made my day. I have been wanting coffee cake but not a whole cake…tonight my craving shall be cured. 🙂
Another great single serving recipe! You’re awesome!
coffee cake is my FAVORITE!! i will be making this tomorrow 🙂 thanks for another wonderful recipe!
Oh my goodness. I’ve always wanted to try a mug cake but ~400 calories for a little cake that comes out spongey? No thank you!
Definitely trying this, thanks Katie!
way to set the week off right! Looks just sooooo good!
Oh my Katie, you’ve outdone yourself! This looks absolutely scrumptious.
Do you prefer the oven or microwave version?
Oven baked goods will almost always have a better texture than microwaved ones, but the microwave is faster, so it’s a trade-off depending on what you’re looking for– best taste or convenience.
Devine!! I’m making this ASAP!
Being a bridezilla is the recipe for a crummy wedding!! I got married recently and had the best time of my life because I cared about one thing, marrying my husband!!
I really do love weddings, and I always have. I think it’s probably the result of watching Father of the Bride over and over again as a child 🙂 I just went to a wedding over the weekend and loved every second of it!
Hey Sweetie – this coffee cake looks tasty, tasty, tasty!!! I can’t say how much I appreciate the WW points in the nutritional info! No need to worry about conversions from cals to kilojoules!! So easy and great because most of the WW snack bars/etc we have here are full of wheat and other stuff and I really need to lose some kilos (or pounds!) but you need something right? You betcha! 3 points for a snack is really good!
I can’t say I’ve ever endured a bridezilla but I have endured a mother-of-the-bridezilla once when I was a bridesmaid! Your Mum’s maid sounds like a real trouper though! What a good friend!
That looks amazing! I’m maid of honour for my friend’s wedding this summer. We’re having the stagette next weekend!
That’s really clever! I bet you could make all sorts or variants on that!
