My hot chocolate cake is an intensely rich chocolate cake made with one and a half cups of real hot chocolate, iced with cocoa frosting, and layered with marshmallow buttercream. Make it as a three layer 6″ cake, or a two layer 8″ or 9″ cake.
I was going to write about how my great-grandmother passed away last week, but I wasn’t sure how to do that on my blog. Here, I try to revolve my stories around food, and the death of a loved one doesn’t have much to do with chocolate cake.
I wanted to write about how we celebrated her life, her humor, and her faith last night while at the same time we mourned her loss. Family and friends packed into the too-warm funeral parlor, dressed in itchy black and gray clothes, and my sisters and I made sure to wear leggings under our skirts because, were she alive, Mom-Mom would have commented loudly about the indecency of the “short” skirts that brushed modestly at our knee caps.
Instead, it would be more appropriate to devote this post to talking about how rich this cake is, shamelessly using the word moist because it is saturated with chocolate, melting in your mouth, decadent; but all that’s coming to mind currently is fettuccine noodles in pools of grease-speckled tomato sauce, ladled onto my plate by her shaking hands as she reminded me for the twelfth time to “Make sure you have enough to eat”.
I’d want to write about her last birthday, her 101st, tuned to the theme of 101 Dalmatians. Or how She loved God, her family, and the Orioles. How many things she saw in 101 years, from the Great Depression to iPhones.
This space is more appropriate for talking about cakes, though. Did I mention this cake is accented with a marshmallow buttercream? It’s buttery and smooth and meant to mimic the baby marshmallows that I overload into my mug each time I make hot chocolate, coaxing them under the cocoa surface with a spoon until they are slippery and disintegrating. The pictures here don’t do justice to the flavors.
Pictures. There were so many pictures in the funeral parlor. Not 101 years worth, but the highlights. So many smiles in black and white and in color, 5 generations surrounding her, lots of pictures of her dancing, even at my wedding just over a year ago.
My favorite photo was not that, or any other staged one. My favorite was one taken when she was 98; in it two of my college-aged cousins look on as she tosses a ping pong ball toward a triangle of red plastic cups. It looks like she just crashed a beer pong tournament at a frat house. The picture was probably snapped quickly with a phone, but the photographer immortalized her spirit in the moment just after the toss, determination firm on her face, the ball aimed squarely for its target. She was a good shot, evidently.
I think I’d feel inclined to note that Death at 101 years is not a shame, and it’s certainly not a tragedy. No long illness kept her shackled to a hospital bed; she was spritely and full of humor, happy and so grateful for life until the end.
But it’s still sad to lose a loved one, no matter how prepared you think you were, to register the finality of death and what it means for future family gatherings. We mourn for the loss of her laughter and jokes and attempts at rapping at Christmas, for the loss of her fiery presence. We mourn for ourselves, more than anything.
Instead I should write about this cake.
Besides, what could I say in a post that could do justice to the legacy left from over a century of well-lived life.
It just wouldn’t be possible.
This hot chocolate cake is really, really good.

Sorry for your loss ❤️
Maariyah
Can this be made into cupcakes?
Sam
Hi Maariyah! This should work just fine as cupcakes. 🙂
Ella Sultana
Hi, I have an 8.5” cake tin and want to make this 3 tiered.. can i double the recipe?
thanks!
Sam
Hi Ella! This recipe will make a 2 layer 8 or 9 inch cake. If you need 3 layers of 8.5 inches each you can just increase the recipe by 50%. 🙂
Laura
Hi Sam,
Not sure where you are located but I would love if you added options to help out us high altitude ladies. I usually add a little flour but if you have other tips or tricks I am all ears.
Thanks
Laura from Colorado
Sam
Hi Laura! Unfortunately I have never baked at a high altitude so I am not sure what alterations need to be made so I really can’t comfortably add tips for high altitude baking. 🙁
k
so good! the cake is amazingly moist and fluffy. loved it.
Sam
I am so glad you enjoyed it so much! 🙂
Soni
2/3 cups of oil??? Does this mean 2 or 3 cups? I need correct measurement pls… Is this correct as seems like a lot, also can you give the measurements in ML since it’s a liquid ? Thanks
Sam
It is 2/3 cup not 2 or 3 cups. You should be precise in your baking. In ML that is 158ml. 🙂
Winona Entwisle
Hi Sam! Would this cocoa frosting recipe be good with your vanilla cake recipe? Need to make a birthday cake and ingredients are limited right now so can’t do the fancy frosting recipe w semisweet choc and hubby says no thanks to cream cheese frosting. Any other suggestions?
Thanks!!
Sugar Spun Run
Hi, Winona! Yes, this frosting would work well on my vanilla cake recipe. Depending on what ingredients you have on hand, I have a few other options that you could try: peanut butter frosting, swiss meringue buttercream, or chocolate frosting. I hope that helps! 🙂
Sue
What a lovely tribute to your great grandmother. It’s always a pleasure to read your posts and this one, especially so. Your writing is magical and so are your recipes. I made your hot milk cake 2 days ago (yum!) and today I woke up and decided to make this one after finding a mocha mix in the back of my kitchen cupboard. Ridiculously moist and chocolatey, it was perfect even without any frosting (did not have all the ingredients for frosting). I come from a family that doesn’t bake at all and reading and trying your recipes has been a true joy for me (and I suppose, my friends and family who get to taste 😊). Thank you ever so much!
Sugar Spun Run
Thank you so much for your kind and sweet comment, Sue! I am glad that you have enjoyed my blog and my recipes. I am happy that I can bring you some joy in these uncertain times. Thank you for trying this recipe, I happy you loved it. 🙂
Dee
I had to add a little milk to the marshmallow buttercream….. before the milk it was just super stiff and clumpy…. the milk made it perfect!
Sam
So glad you enjoyed! 🙂
Bridgette Mady
would you mind sharing the hot chocolate recipe you use? I have so many I love, but would love to try yours! I can’t wait to make this for my family this holiday season :))
Sam
Hi Bridgette! I just use a hot cocoa packet mix using milk, or I get it from a coffee shop. 🙂
Bridgette Mady
perfect, thank you so much lady 🙂
Sarah Pourhosseini
Do you think this cake would work with your vanilla buttercream frosting? My sister is wanting a two tiered cake for her daughter’s first birthday (one tier white, the other chocolate) so I’m needing to keep the frosting consistent. Any suggestions would be much appreciated!
Sam
Yes, it would work well with that frosting 🙂
Shannon
Can the marshmallow buttercream be made a day ahead? I am taking a hot cocoa bundt cake to work & want to give folks the option of using a marshmallow frosting – your recipe sounds super yummy! – which would be served in a bowl on the side. Would this frosting stand up to that?
Sam
I don’t think that would be a problem at all! Hope you love it!
Pink Britt
Ummm. I used 3 six inch pans, was careful to only fill 3/4 way full.. they are up over and all over my oven. Checked all measurements twice. Any suggestions?
Pink Britt
Nevermind. Batter started an oven fire that would not quit. Had to put it out with a fire extinguisher. LOL! I’ll try again after new years.
Sam
OMG! Yikes! Sorry to hear about that… I have never had my cake rise so much/overflow and I make this one frequently so I’m afraid I’m not sure what may have gone wrong. Sorry to hear about your fiasco!!
Katrina
My batter seems super thin – is that right?
Sam
Yup! 🙂
Cecelia
I searched all the way through the comments hoping to find one saying this. Lol
Stacey
About to put this cake together but I’m curious if the cocoa you used for the frosting is unsweetened or hot cocoa mix? Thank you!
Sam
Hi Stacey, sorry I’m just now seeing this, I just use unsweetened cocoa powder for the frosting.
