You’re not crazy, are you?
Yeah, me neither. 😉
When I heard today was National Coffee Break Day, my first thought was to write a post highlighting all of my previously-published coffee recipes. But then I decided posting a new recipe would be much more fun… especially if said new recipe involved coffee and chocolate! (Chocolate is always more fun.)
So I came up with something I’d been meaning to try for a while: a mocha version of the popular One-Minute Chocolate Cake:

One Minute Mocha Mug Cake
Topped with Homemade 4 Ingredient Ice Cream.
- 1 tablespoon plus 2 tsp cocoa powder
- 3 tbsp spelt, white, or Arrowhead Mills gf flour
- 1/2 tsp instant coffee granules, decaf if desired
- 1/8 tsp salt
- 2 tsp granulated sugar or xylitol
- 1/4 tsp baking powder
- pinch uncut stevia OR 1 additional tbsp sugar
- 1 tbsp coconut or veg oil (Edit: many commenters have said it still tastes good if you sub applesauce or mashed banana. I can’t personally vouch for the results if you make that substitution.)
- 3 tbsp milk of choice
- 1/4 tsp pure vanilla extract
Combine dry ingredients and mix very, very well. Add liquid, stir, then transfer to a little dish, ramekin, or even a coffee mug. If using a microwave, cook 45-50 seconds (or more, depending on how powerful your microwave is). If using an oven: cook at 350F for about 14 minutes. If you don’t want to eat it straight out of the dish, be sure to spray your dish first (and then wait for the cake to cool before trying to remove it).

What are your favorite sources of caffeine?
Coffee? Tea? Chocolate? If you don’t already know mine, you must have forgotten what blog you are on!















Holy cow! This 1-minute mocha cake was great. I’ve tried a lot of single-serve microwave desserts and this is hands down the best. Great dark chocolate flavor and good texture. I made mine full-fat version. Will be making again!
Would you consider adding baking time in the oven
For those of us who do not use microwaves? It would be so helpful.
Thank you. Love you recipes.
It looks like other commenters have used the oven, so you definitely can do that. I would try 325 and look in on it after ten minutes but it might take more.
I have just discovered your website and is the best!!!!. Especially the single serving sweets. Thank you, no more guessing about desserts.
this is amazing! thank you 🙂
delishious! I tried to sub the flour w/ coconut flour and the oil with yoghurt, and it tastes almost the same! really awesome recepie katie!
Hi, just tried this one and it turned out like a crumble. What did I do wrong?!
Can you give more specifics than that? What flour did you use? Also, did you read through CCK’s FAQ page at the top of the blog?
Chocolate and coffee…u got me girl. I’m going to follow your blog right away 🙂
I just two of these for my husband and I as it’s his birthday but we are going out for dinner tonight so didn’t want to make a full cake – it was fab! I only just read the comment about subbing the oil for greek yogurt so think I will use that as an excuse to make again and try that way 🙂 Thanks Katie, you are always my first stop for fab treats…
Just made this without oil, used the 1TBS mashed banana instead! All I can say is YUMMMMMMMMMMMM!
Thank you so much for this recipe!!! I almost gave up on mug cakes. Every recipe I tried just didn’t make the cut but this one is perfect. My other half is not big on sweets so I try to minimize my portion sizes and this was perfect for me. I cant thank you enough.
By the way. . .I don’t drink instant coffee so I didn’t have any on hand. I just eliminated it and the recipe was still awesome. I make a chocolate cake that uses coffee and it is the best in the world (in my opinion) so I know chocolate and coffee makes for a great recipe. This is just a tip for those who may need that quick chocolate fix like me but do not have instant coffee on hand.
