Meet my new obsession: 30 Minute Chocolate Cake For Two. I was tempted to call it 28 Minute Cake For Two, but it didn’t roll off the tongue in the same way. It’s a triple layer cake of chocolate goodness that is perfect for sharing. No longer are the days of making cake and having leftovers for days. This cake is the perfect size for you and a buddy. Or for just you, depending on how your week’s been going.

The secret to this cake being done in 30 minutes? Cooking it in the microwave. But unlike some mug cakes, this one doesn’t taste spongey at all. I couldn’t help but marvel at the texture- it’s just like that of a cake from the oven! Alex said today it’s one of the best cakes I’ve ever made. I did a little dance.

And it is totally Valentine’s Day appropriate without being over the top. Your Valentine will love you for making something the two of you can enjoy, and will also thank you for skipping the whole candied hearts and chocolate roses thing.

Want to hear a fun story about this photo shoot? I shoot everything in our bedroom, and the setup is pretty makeshift. For this shoot I put a black board by the end of our bed, and placed wood on a chest in front of it.

So I’m taking pictures and things are going well, and at the end of the shoot I decide to sit on the bed to go over the shots I’ve taken. I take my camera off of my tripod and do a little jump onto the chest and land on the bed. Then I hear a lot of crashing behind me.

I look back. The black backdrop has fallen on top of the cake, the milk bottle is horizontal, and the milk is slowly making its way down the chest and onto the floor. It was like Niagara Falls.

End of photoshoot.

Luckily, the cake didn’t get too smushed, and the milk cleaned up easily. Alex and I happily ate the fallen cake last night, and it was still delicious.

One thing I will mention about this cake– microwaves greatly vary in the time it takes to cook things. The cake should spring back to the touch after being cooked. If you find that your first mug is over/undercooked, adjust your time by ± 10 seconds for your next two mugs.

Without further adieu, please go enjoy this 30 Minute Chocolate Cake For Two. You won’t regret it!

30 Minute Chocolate Cake For Two
 
Prep time

Author:
Ingredients
For the cake
  • ½ cup sugar
  • 7 tablespoons all purpose flour
  • 3 tablespoons cocoa powder
  • ¼ teaspoon baking powder
  • ¼ teaspoon baking soda
  • ¼ teaspoon salt
  • 1 egg
  • ¼ cup milk
  • 2 tablespoons canola oil
  • ½ teaspoon vanilla extract
  • 2 tablespoons water
For the frosting
  • 4 tablespoons butter, room temperature
  • 3 tablespoons cocoa
  • ½ cup powdered sugar
  • 2 tablespoons milk
  • dark chocolate shavings (optional)
Instructions
  1. In a small bowl, mix together all dry cake ingredients with a fork. Add in wet ingredients, stirring until combined. Heavily grease three large mugs* and evenly distribute batter into mugs (~1/2 cup of batter each).
  2. Microwave each mug by itself for 1 minute on high. Remove from microwave and shake slightly to loosen cake from mug. Flip mug over onto parchment paper-lined plate or board. The cake should drop right out. Repeat with remaining mugs, then place into freezer for 5 minutes, or until the cakes cool to room temperature.
  3. While the cakes are cooling, make the frosting. Combine all ingredients in a standing mixer and beat on high until light and fluffy, about 1 minute. Remove cakes from freezer and frost the top of each layer before stacking. If using, shave dark chocolate over the top of the cake using a sharp knife.
Notes
*don't have 3 uniform mugs? Use one, cleaning thoroughly between cooking each layer!

what kind of mug??

Hi Ronnie! I used a flat-bottomed mug that is 4″ in diameter. You can also use a 4″ ramekin!

Turing a mug cake into a three tiered cake is really genius, Sarah. I love it! And ugh – the photoshoot. Sounds messy. I’m squirming just thinking about it.

Haha, it was awful. And thank you!

I love how you turned mug cakes into something classy. And yeah, imma eat this on my own. And since you’ve made it so easy, I’m probably going to have it like once a week.

The end of your photo shoot sounds a lot like one of my shoots! The other day I accidentally broke this little glass flower holder I was using to prop up my back board. #oops

Looks so good! Can almond milk be substituted in for the regular milk?

Absolutely! Use the same amount.

Glad to hear the cake survived. Would hate all this chocolate yumminess smooshed against the black board! Looks perfectly yummy!

Wow, what a gorgeous little cake 🙂 I love how perfectly moist and decadently chocolatey it looks! I’m so glad your cake wasn’t too injured in your photoshoot, that would have been tragic!

Chocolate cake in 30 minutes?! I am in! Pinned! This looks amazing Sarah!

I’ve had limited success with mug cakes thus far. They look like little half dry/half damp piles of mess, but I pile on the whipped cream and chocolate and consume them anyway. But this cake looks absolutely phenomenal, and I can’t wait to try it and become a Microwave Cake Master!

Heck yeah! It’s so delicious, and far from dry 🙂 You’ll love it, Meagan!

Hellooo! Text me a picture of how it turns out 🙂

Listen. I was completely skeptical about this whole situation. But you haven’t steered me wrong before so I gave it a try. These little cakes, which basically souffle an inch out of the mug, were awesome! I dropped a few chocolate chips into the mugs as they each took their turn in the microwave and topped them with some leftover peanut butter frosting we had 🙂 I’m still not exactly sure what happened, but I will say that from the time that I pulled up the recipe until I was eating cakes, only 15 minutes past. Highly recommend these to everyone, ASAP.

I’m so glad you enjoyed the cake, Mike! And I can only imagine what they tasted like with peanut butter frosting. Ohhhh man…. Keep on baking & letting me know what you make!

Okay, so I’m really tempted to make this, but – your cakes look so flat and even and beautiful! I’m sure mine would just look like the bottom of a mug, and I’m wondering if a 6 oz ramekin would be big enough.

Sarah | Broma Bakery
Reply

Hi Diane! I think a 6 ounce ramekin would be a little small, but would absolutely work! If you use it, you’ll probably end up with extra batter. I would still do 3 tiers, but use closer to 1/3 of a cup of batter in the ramekin. Last, I would do 45-50 seconds in the microwave instead of 1 minute. Good luck & happy baking!

I want to make this now, omg. Except I’m a little nervous because the microwave we have is so shitty and does horrible things to the food we heat up. But this sounds so delicious and it’s so pretty and perfect looking! I love the idea of a multi-layer cake from the microwave!

Sarah — This was another winner! I agree with Mike; this was a high-speed soufflé in a mug. Genius! My husband and I just had this for Valentine’s Day and we were floored. Thanks so much, Sarah!

Hahaha, at least you got some gorgeous photos of it before the fall! This cake is to die for — so fudgy!

Hi Sarah,

This looks so good! What size mug did you use? Thanks!

Hi Darcy! I used a mug that is 4″ in diameter. In other words, use the largest mug you can find! Happy baking 🙂

Hahhah my backdrops fall all the time. So annoying when there is frosting or it is your smoothie glass knocked all over. Oh well…the glories of food photography.

Reply

This is officially the cutest thing I have ever seen! Can’t wait to make it, as it sounds so easy. It’s so hard to bake cakes when it’s just me and my husband. We end up tossing a lot, as we can’t possibly eat all the leftovers. This is the ultimate perfect solution. lol

Reply

Okay so now I’m totally stocking your site and drooling over every recipe. I LOVE this idea! I wish I would’ve seen it before v-day but am pinning and forsure making on my next date night! And photos are amazing btw!

Reply

Ok this looks absolutely fantastic and i can’t wait to try this one 🙂 but i have a question (which mal sound really dumb but i am the total absolute baking – noob so I am completely helpless besides receipts) how long and what temperature would it take for those microwaved mugcakes if i made them in the oven? ^^”

Sarah | Broma Bakery
Reply

Hi Maggie! That’s a great question. As I haven’t tried baking them in the oven, I’m not sure, but I would try 350°F for 5-10 minutes. After the first 5 minutes, check the cakes for done-ness by sticking a knife int he center of the cake. If the knife comes out mostly dry, they’re done! Hope this helps and happy baking 🙂

Ours was a delayed Valentine celebration, but thanks to this recipe an absolutely delicious one. Well worth the wait.
And without further ADO, I will make again for my chocolate-loving husband and son.

Hi Katja! I used the largest mug I have- 4″ in diameter. Hope this helps and happy baking!

Thanks, it was really delicious, but i had 3 cakes. My layers were rather thick, so i put cream on each one and served them to my friends. 🙂

Can’t wait to try this! But I prefer vanilla frosting. Do you have a good recipe?

Sarah | Broma Bakery

Hi John! There are a lot of good vanilla butter creams out there. I really enjoy Martha Stewart’s basic buttercream recipe. Hope this helps!

Reply

Oh my goodness. This was so good. And easy. What made it even better was that it is a microwave cake (didn’t realize it until after I made the batter). I didn’t make the frosting because we had some opened already but I’m sure the frosting would be just as great. Thanks so much!!!

I am a chocoholic so am going to make this and when I make a regular size cake it never gets all eaten as we are not big on cakes so will try this and thanks but could you put what the calories and fat count is would be nice for us on weight watchers thanks again

Wow! Made this scrumptious cake today and gotta say, it’s outstanding! The texture truly IS that of a normally baked cake, rather than the tough, gummy consistency of other microwave mug cakes I’ve tried. This is definitely my new “go-to” for a chocolate fix. Thank you so much for sharing such an easy-peasy recipe! Yum!

Hi Sarah,
This cake looks amazing. I have some 4″ diameter ramekins, but I am not sure if they will be deep enough. Approximately how high did each layer rise? Thanks!

Sarah | Broma Bakery
Reply

Hi Bennie! Each rose about 2 inches high. They are thicker layers! But I’d assume that ramekins would be an OK height. You can always put a little less batter into each one, too. Hope this helps and happy baking 🙂

Reply

I love this cake! (And your pictures are beautiful!) Anyway, the cake is AWESOME if you add chocolate chips, and almost as good if you add peanut butter, though you do need to cook it for about 5 more seconds. Have fun experimenting!

Reply

What did I do wrong? I used only 1 mug to make 3 layers. The first layer was as high as the mug (about 4″) After washing the mug and heavily greasing it again, I added about 1/4 cup of ings into my mug. Still way too high! I double checked my ingredients and directions. There was no way this could be stacked. The smallest layer was the size of a cupcake. Other than being unstackable,( it made 2 cute big cupcakes and 1 large “tower of Pisa”), it was tasty.

Reply

Hi Sarah,
This cake is unbelievable! I usually think of mug cakes as nothing more than sweet, rubbery pucks, but this cake is the REAL deal! The texture is moist and light—the chocolate flavor is intense and delicious. The fact that you can make this good a cake in such a short amount of time is wondrous! Thank you so much for sharing this recipe. (Of course, come beach weather, I may be cursing your name!)

Reply

Just finished making this cake and it was amazing!! I used egg substitute though and I used 4″ ramekins. I filled the first one a little too much so it spilled over but I filled ones after about halfway and they were perfect. I actually got 5 cakes from this recipe. And they were uber moist and rich. Loved them!!!

I did it today for my spouse birthday. It was a total total success. I have to thank you, he has s like a little kid if there is not birthday cake. From now on this will be my receipe. I will say it to s for 3 months re than 3

Is the cocoa unsweetened or drinking cocoa?

Thank you!

Hi Vlau! It is unsweetened.

COULD YOU ADD the oven instructions.. i don’t have a microwave!

Sarah | Broma Bakery
Reply

Hi Bobbi! It’s all a guestimate, but I’d say 350° for about 20 minutes. This recipe is specifically made for the microwave, so your cakes might not come out as well unfortunately! If you’re looking for a great oven-friendly recipe, I’d suggest this one, and halve the recipe and bake it in a small mug like this recipe calls for.

Reply

Hi Sarah! I just discovered your website and got subscribed (everything looks amazing). I read this cake recipe and immediately tried it. Mine I have to say it didn’t look not at all as amazing as yours. I don’t know what went wrong, the “crumble” on the side looks very “open”, and the cakes didn’t come out of the mug so perfect. 🙁 Do you have any suggestions for next time?

Sarah | Broma Bakery
Reply

Hi Marcela! It must be an issue with greasing your mugs. I greased mine HEAVILY to keep them from sticking to the mugs. I would absolutely try that next time!
