Two Minute Chocolate Mug Cake. A Fancy Cake in a Cup.

At this harrowing time in our lives I think it’s safe to say that there has never been a greater need for Cake in a Cup.

Cream ironstone cup filled with overflowing chocolate cake, topped with raspberries and a snowbank of powdered sugar.

Like most people, I can tell you exactly where I was during certain momentous world events.  When I found out John F. Kennedy Jr. died I was talking on the phone to my friend Renee. For the O.J. Simpson verdict I was in the lobby of CBC television studios.  And for Cake in a Cup, I was browsing Stumble Upon.

Remember Stumble Upon? 

After seeing the recipe for Cake in a Cup I jumped out of my computer chair and bounced, Tigger-style towards the cupboard.  Everything I needed to make an actual chocolate cake inside of a coffee cup in 3 minutes FLAT,  had been inside  my cupboard my whole life and I had NO idea.  

Cake in a Cup Recipe (s)

This good old cake in a cup takes basic cupboard ingredients like flour, sugar  and cocoa to make what is essentially an INSTANT cake that you cook in the microwave.  

Perfect for a midnight snack, easy dessert or binge watching buddy while you’re living the life of a shut in. The perfect companion to Netflix is mug cake. Everyone says so.


Cake in a cup ingredients laid on a wood board including cocoa, dark brown egg, flour in an ironstone cup, sugar and a mini glass pitcher of milk.

What’s in it?  Basic ingredients:  flour, cocoa powder, sugar, baking powder salt, milk, vegetable oil.  An egg and chocolate chips are optional.

The one thing this cake doesn’t require is love. THIS IS NOT A CAKE MADE WITH LOVE, it is a cake made out of insanity and necessity.

How do you make it? Just like a tiny cake. Mix your dry ingredients like the sugar, cocoa, baking powder and flour together in a microwave safe mug.

Stir them up well.

Add in your wet ingredients.

Chocolate cake in a cup ingredients mixed in with dry and ready to cook in microwave.

Stir those up.

And then cook it as all the world’s best desserts are cooked – in the microwave on high.

This is O.K. on it’s own, but really like my sour cream, cilantro, cheese topped homemade chili, it’s all about the toppings.  Add frozen berries, powdered sugar, whipped cream or chocolate shavings to elevate this chocolate mug cake. Or, ORRRRR top it with a scoop of vanilla ice cream. 

That’s how you turn this into something – well, something a little more impressive than what it is – an emergency dessert to be used in dire circumstances. Like right now.

I made this recipe on one of the bazillion television shows that I hosted.


This cake in a cup recipe is to be used in a chocolate craving emergency! It’s kind of like jello … you might not want to serve it at a dinner party, but sitting all by your lone self in a bathrobe on the sofa it’s perfectly acceptable.

Now, let’s be honest here for a second, shall we? I know this is the Internet and that sort of thing is often frowned upon, but just for kicks … let’s be honest.

CAKE IN A CUP IS GENIUS! It may be the greatest invention ever, second only to potato chip flavoured toothpaste (fingers crossed someone has this one in the works).

Is it the most delicious cake you’ve ever had in your life?  Well, that depends on how drunk you are.

It’ll certainly be the most fun and fastest cake you’ve ever made in your life.

I expect you’ll be adding this  to your very own list of “remember where you were” momentous occasions.

Cake in a Cup.

It's hard to believe this ridiculous recipe works but it actually does. Ease your chocolate craving immediately!

  • 4 Tbsps flour all purpose or cake
  • 4 Tbsps sugar
  • 1/4 tsp baking powder
  • 2 Tbsps cocoa
  • 2 Tbsps vegetable oil
  • 5 Tbsps milk
  • 1 Tbsp Chocolate Chips


  • Add dry ingredients to a microwaveable mug.   Stir to combine.
  • Add oil and milk.
  • Mix well, making sure to incorporate all the dry ingredients hiding at the bottom of the cup.
  • Top with a couple of tablespoons of chocolate chips. These will sink down into the middle of the cake when you cook it.
  • Microwave on high for 1.5 minutes.*



You can also add 1/2 of a beaten egg - which is about 1.5 tablespoons of beaten egg. If you add egg, reduce the amount of milk by 1.5 tablespoons.  Using egg will make the cake spongier.
The power of your microwave will dictate how long to cook the cake for. A stronger microwave (950 watts) will cook the cake faster in just over a minute. An older, or weaker microwave will take 1.5 minutes.
If you overcook this cake (and you might on the first try) it will be dry and ruined. 
Take this cake WAY over the top by dusting it with powdered sugar and topping with jam or frozen fruit. Raspberries are my go-to.
  • Cut the sugar back to 3 tablespoons and omit the chocolate chips to save over 100 calories.

For those of you who don’t know (my mother) Stumble Upon was an Internet network from the olden days (before Pinterest) with some of the best information on the Internet.  Quick hits of brilliance.   And a few toads.  It still exists by the way, under the name of Mix.

Two Minute Chocolate Mug Cake. A Fancy Cake in a Cup.


  1. Leanne says:

    I feel like I am about to ask a question that is going to change my life forever. reverently whispers… What is stumble upon?

  2. Alyson says:

    Stupid Karen. I JUST discovered your blog,showed my daughter the stupid cake in a cup recipe – and now she makes it all the time and leaves the cakey cup on the drainer and looks at me all innocent with cake moustache on her 10 year old face saying there wasn’t enough to make two. She hides the cocoa, I know it. Stupid kid.

  3. Karen: In response to jj’s post above, I don’t know about lowfat but how about a no fat version?

    Air in a Cup.

    Instructions: stare at a microwaveable ceramic cup and think hard about whether you REALLY want to bake anything cake-like in it that will just go to your hips anyway. Then, just walk away.

    There you have it; the no fat version. AIR IN A CUP. Pure genius :)

    South Beach Diet, why have you made me such a cynic? I think I need to eat cake. NOW. Excuse me for a moment while I go search the pantry.

    My advice to anyone still following this thread: if you’re gonna eat cake, go for the full meal deal. In a cup no less! Carpe diem!

  4. jj says:

    If anyone comes up with a lowfat version of this please post it!

  5. Jerry says:

    A pinch of chili powder goes wonderful with chocolate. Chocolate anything.

  6. Pam'a says:

    Thank you, thank you, Karen– Cake in a Cup has made for some lovely moments with my beloved, who has now stopped pining loudly for the “Pie Delivery Truck” every night after dinner.

    Oh! p.s. If you don’t have any of that fancy-schmancy self-rising flour around, there’s a fix: Add a TEENSY pinch of baking powder (I worked it out, and it’s roughly a 1:48 ratio) and use a bit less flour–what the pros would describe as a “scant” 4 Tb.

  7. Jennifer says:

    OMG, that is friking fabulous!! Can’t wait to try it and show my SIL!!!

  8. Zina says:

    I am so going to do this with my nieces when I get back to the UK.

  9. Nicole* says:

    I’m new here and I’m really enjoying your blog – so funny!
    this cake sounds awesome – is 11:18pm too late to cook a cake in a cup?

    • Karen says:

      Absolutely NOT too late to make cake in a cup. It’s NEVER too late to make cake in a cup! Thanks for visiting! – karen

  10. Tickled Red says:

    Shhh…don’t tell the monkeys it’s that easy! They will be eating chocolate cake 24-7 and swinging from the ceiling fan. :) Wonderful post darlin’…that’s actually a brilliant find.

  11. JennyM says:

    Have you ever made Egg In A Cup? I’m not sure a scrambled egg needs to be simplified, but it makes the perfect size egg… uh, puck? to put on an English muffin, and all you have to wash is a coffee cup.

    Quick shot of cooking spray into a mug.

    Crack in one egg.

    Beat egg with fork.

    Add small pat of butter and splash of milk or water. Some shredded cheese if you have it. Give it a good stir.

    Microwave on high for 1 minute at 50/60%.

    Ta da!

  12. Nadine says:

    A.MA.ZING. How have I made it this long without a cake in a cup? Thank you for changing my world.

    PS: you can use regular flour if you need to!

  13. Amanda says:

    I made this last night –so ridiculously easy! And, pretty delicious for something so simple. I think I’ll add butterscotch chips, and walnuts next time for a bit of flare. But, cinnamon & cardamom might be really nice, too :) Thanks for sharing this, Karen! Lovin’ your blog!

  14. alicja says:

    Ok. My first post here :) I come from Poland, and that`s were I live. I can hardly understand what you`re writing (I was always better at german) but, nevermind, you make me laught EVERY SINGLE TIME, when I read your blog :)
    It`s totally crazy. I laughed when I was reading about yoghurt tampons. Actually I died with laugh ;)
    That`s for the beggining.
    Next- I`m not sure, what is the difference between sailboat and fibregals sailboat, but, that`s what I found once:

  15. allison albainy says:

    Apply for Oprahs show…You are already great…You would win! PFFFTTTTTT! :)

  16. Heather says:

    I put a pinch of cinnamon in my cake in a cup. It plays nicely with the density of the chocolate.

  17. Joni N. says:

    But I don’t have any self-rising flour.

  18. Jessica says:

    I agree with Kate – I don’t even know what Oprah’s show giveaway is, but I’d vote for you fo’ sho’!

  19. Jessica says:

    I second that, Oonafey. I’m shit out of luck. No microwave AND my oven doesn’t work. So no Cake-in-a-cup OR plain old oven baked cake for me. Grocery store cake. That’s where it’s at.
    Hey, Karen! Wanna add “How do you fix an oven on a 50’s gas range?” to your “Ask Karen” list?

  20. Damn. If only I had a microwave.

  21. Lori says:

    Must. Try. Now. Oh my.

  22. Kate says:

    AMAZING!! Plus I think you should apply for Oprah’s show giveaway that she is having! I would love to watch all your blog ideas on the TV!!

  23. Courtnet says:

    This is genius! My kids will love it!

  24. Sara says:

    Occasion #1 – “Stumbling” and link clicking a week ago and found your site!

    Occasion #2 – At the library a couple months ago looking at some pastry cookbooks and found “101 Recipes for Microwave Mug Cakes”…of course I checked it out. Can’t believe I’ve had all these mugs sitting around here with nothing in them but coffee, tea and hot chocolate…pfttt

  25. Christina says:
