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 am sooooo trying this in the morning! I love the healthy subs you can make for just about ANYTHING there is out there. they are almost always a success for me! I am ordering your cookbook on amazon too =)
I made this tonight it was super easy and delicious. It seriously hit the spot. I tripled the streusel and I added a little cinnamon to the actual cake part and it was moist and delicious and ready in under 10 minutes. Next time I would like to also whip up a tiny bit of cream cheese icing for this.
I just made this & it was absolutely delicious! To try to make it as sugar free as possible I subbed in date paste (just blended dates and water) for the sugar in the “cake” and left out the water: it was so so so good! I didn’t even feel guilty after eating it! Thank you for a great, easy recipe!
Wow, just made this for breakfast and I have to admit, I was skeptical. I used the microwave method and it was delicious- and so quick and easy! So much so, that I MAY have made a second, which totally negates the whole single serving point of it all, but I just couldn’t help myself. Thanks for this!!
Do you have the conversion amounts for making these by the dozen? I would like to make a big batch of them to freeze or share.
If you have her cookbook, the Cappuccino Chocolate Chip Muffins are very similar and I definitely have frozen them before. I’ve made at least three batches since getting the book!

Wow! I want to try this for breakfast tomorrow morning. I love your pics by the way, they look amazing, as usually! Thanks for sharing all your awesome recipes! You do an amazing job! 😀
If i don’t make the streusel, will the test be too bad?
How much calorie it will be without streusel?
