Single Serving Mocha Chocolate Cake

cake for one

The rich chocolate mug cake displayed before your very eyes can be made in under 5 minutes.

And it serves just one person.

Unless you’re crazy and decide to share…

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:

cake for one

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).

In honor of today, serve with Copycat Healthy Starbucks Frappuccinos.

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!

      That is exactly what gets me too! Sure, I can eat one serving when I make a big batch of something. But I just can’t waste it by throwing it out when it gets old and stale! Glad I’m not the only one with the logic of finishing it off so it doesn’t go bad!

  1. Jess says

    ps – this looks absolutely decadent. Too bad we already have a chocolate-lemon cake in the fridge that needs devouring c:

  2. Anna Lynn says

    As I sit here and drink my huge sugar-free, skim-milk fru-fru coffee drink from my favorite local coffee shop, I can safely say that I am a coffee addict! This year, I began drinking it in some form everyday…probably not the greatest (or healthiest!) idea, but my schedule is insane and the caffeine is a lifesaver some days! This recipe makes me incredibly happy because I love chocolate just as much as I do coffee so seeing this combination definitely made my morning!

  3. Sarah the official CCK drooler says

    Coffee and chocolate. Hello, sugar high! Maybe you can do a coffee and chocolate ice cream? Or cupcake?

  4. Rachael says

    I know this might sound crazy but can I make this recipe without the coffee? What would I sub? I’m not a coffee fan and don’t keep any coffee around!

  5. Qi Ting @ A Dessert Diet says

    I love coffee-flavoured things! But I can’t stand coffee itself (too bitter for my palette). So my favourite sources of caffeine are coke and chocolate and tea 😀 I’m not too good at sharing either. This looks perfect! 😀

  6. Zoe says

    I am stuck in my house due to snow and freezing rain. Feeling a little sorry for myself and needing something to make me feel better…yep – this is exactly what I needed!

  7. Emilia says

    Yum! this looks so good, I love the combination of chocolate and coffee. Coffee (preferably high-quality and maybe single origin) is definitely my favorite source of caffeine, though chocolate does come in a close second 🙂

  8. Bianca- Vegan Crunk says

    OMG, I’m soooooooooo in need of a cup of coffee right now. I have four days left in my 21-day cleanse and the thing I miss the most is coffee. I’ve been so tired all month. I need caffeine to survive.

  9. Chelsea says

    Oh gosh, Katie! Be still my heart. 🙂 Hmmmm, I don’t have a microwave, so what would you recommend for oven temps and times? Will the cake still be as fudgy? Newly preggo and craving chocolate and carbs…can’t wait!

  10. Katie says

    National Coffee Break Day?! Heck yeah! I’m drinking coffee right this very second – I love it so much. I was actually just thinking this morning how I am glad I’m not pregnant so that coffee can be a part of my life. A very major part.

    This little cake is right up my ally. I’m pretty sure I have to make it today.

  11. Katie @ ohshineon says

    I am definitely going to make this tonight! I’ll probably sud applesauce for the oil and melt a couple tablespoons of dark chocolate to drizzle on top 🙂 I’d take chocolate over oil any day!

  12. jaclyn says

  14. Jen says

    Katie-just made this…and as per usual, it was fabulous!!! Plus, it keeps me on my healthy kick-losing weight and eating sweets has never been better….thanks to you!!!

  15. Kristal says

    That looks divine. On the list for tonights dessert.

    Chocolate, tea, and hot chocolate are my caffeine…. although I really don’t think about the caffeine!

  16. Emily @ Glitz Glam Granola says

    Omigosh, I know what I’m making for dessert tonight!! This looks fabulous and now that I know just how good the original is (I made it for the first time on Monday) I need to try this version! I love coffee and chocolate together too, so this was meant to me. Oh and my family asked for bites of my chocolate cake when I made it and I must have given the smallest bites imaginable– but let’s face it, this is way too good to share!!
