My biggest pet peeve in the world — well, when it comes to Cake — is a dry cake. There is nothing worse than biting into a dry cake. If you have to drown it with a glass of milk to make it edible, it’s a waste of perfectly good sugar! Jorge and I hit up a cupcake shop a while ago and after paying $4 for another DRY cupcake, I was over it.

I posted a sneak peek of this cake last week, so I know y’all must have been counting down the days until I posted the recipe. I made this cake as a thank you for all the help my Mom & Dad did with our recent move. My Mom’s one and only request was Chocolate. I didn’t want to let her down, so I made a super chocolate, super moist Chocolate Cake. Not gonna lie, I think I finally came up with a chocolate cake that beats the classic Hershey recipe. I’m seriously throwing down the gauntlet here, try it and tell me I’m wrong. I dare ya. ;)

Honestly, I thought I was going to pair this cake with a chocolate buttercream…you know, to truly deliver on the single request of CHOCOLATE….but I was out of butter — the horror!! After considering running out for some butter, I decided to turn to one of my absolute favorite frostings, Marshmallow Frosting. Instead of just adding vanilla extract to it, I scraped in a vanilla bean. Whoa baby, so good.

I am glad I didn’t go with a chocolate buttercream…it really would have been too much chocolate. This cake is much better suited to a lighter frosting and I am already dreaming of pairing it with this maple frosting or this salted caramel buttercream. The Marshmallow Frosting was the perfect pairing, however it is not as stuff as a buttercream frosting and tends to move around on the cake. Next time, I will serve the cake in slices with a big dollop of marshmallow frosting on top instead! :)

Dark Chocolate Vanilla Bean Marshmallow Dream Cake is truly that - the cake of your dreams! This divine mixture of rich dark chocolate cake and sweet marshmallow frosting is beyond delicious.

Prep Time 30 minutes
Cook Time 25 minutes
Total Time 55 minutes


For the Cake:

  • 2 cups all purpose flour
  • 1/4 cup cocoa powder
  • 2 teaspoons baking powder
  • 2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 cups water
  • 2 cups sugar
  • 5 oz dark chocolate, chopped
  • 6 tablespoons unsalted butter
  • 2 tablespoons vegetable oil
  • 1 teaspoon vanilla extract
  • 2 large eggs

For the Marshmallow Frosting:

  • 4 large egg whites
  • 1 cup sugar
  • 1/4 teaspoon cream of tartar
  • 1 vanilla bean, scraped (or 2 teaspoons pure vanilla extract)


Dark Chocolate Cake:

  1. Preheat oven to 350°F. Butter two 8 inch round cake pans. Set aside.
  2. In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda and salt.
  3. In a medium saucepan over medium high heat, combine water and sugar. Bring to a boil and stir until sugar dissolves, about 1 minute. Remove from heat and add chocolate and butter, stirring occasionally, until melted.
  4. Whisk in vegetable oil and vanilla extract. Quickly beat in eggs into the chocolate mixture until combined. Whisk in dry ingredients, until smooth.
  5. Divide batter evenly between prepared pans and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
  6. Let cakes cool in pans until cool to the touch, then frost with marshmallow frosting.

Marshmallow Frosting:

  1. Place egg whites, sugar, and cream of tartar in a double boiler over medium heat. Or if you do not have a double boiler, place a metal bowl over a pan of boiling water.
  2. Whisk egg white mixture constantly, until sugar has dissolved and the whites are warm to the touch, 3 to 4 minutes.
  3. Transfer egg white mixture to a stand mixer, fitted with the whisk attachment. Beat, starting on low speed, gradually increasing to high, until stiff, glossy peaks form. Add the scrapings from the vanilla bean, and mix until combined.
  4. At this point you can frost the cake and serve immediately, or as I mentioned above, serve a slice of cake with a dollop of frosting on top (like you would a dollop of coolwhip!)

    So this is now the only chocolate cake recipe I use, it’s perfect! You’re a god!
    But I have question, I am making this cake as the base for my son’s birthday and I’m a bit worried about how long it will stay fresh because its so moist and how to keep it fresh longer.
    I intend to cook the day before the party and ice it but then it needs to be kept for that day and half the next day. Do you have any suggestions?
    We have never had this problem before because previously as soon as its ready to eat its gone!
    Thanks in advance

      I have made it up to 24 hours before and the cake part held up well. However I waited to frost it until an hour before the event.

      My best advice would be to make the cake the day before and store it wrapped in cellophane in the fridge. Then frost it right before the guests arrive.

      …unless you are using buttercream frosting instead of the marshmallow frosting. Then you can frost it the day before with no issues!

      Good luck! :-)

    What a delicious looking cake! I love some good fluffy marshmallow frosting. I’ll have to try this if you say it beats the Hershey’s recipe!

    Made this for my husband’s birthday and he loved it! We are going to use the same recipe and make cupcakes for my son’s first birthday in a couple of weeks. Thanks so much for the recipe!

    This cake recipe is amazing! I got about 18 cupcakes out of one batch, plus a 6-inch (2) layer cake. It is dense and moist and super chocolately…just as a devil’s food cake should be. I brought the cupcakes into work and 3/4 were gone within an hour and a half! I’m so glad I left the cake at home for me to enjoy…I frosted them with a vanilla cream cheese frosting though I’ll have to try it with your marshmallow frosting — it looks amazing. Thanks for the recipe – I know I’ll be making it again and again!

    Dry cake is the worst crime of all crimes – at least in the baking world. This on the other hand would get a Nobel Prize for peace in cake baking.

  6. Amanda @ Once Upon a Recipe

    Dry cake is the worst – I agree, a major waste of calories and sugar.
    Love this combination of rich chocolate cake with a lighter frosting!

  7. natalie@thesweetslife

    I have lots of vanilla beans on hand and am looking for fun ways to use them…can’t wait to try this frosting! :)

    My birthday is this Saturday and I think this is what I’m making! I LOVE a good moist chocolate cake and this frosting sounds delightful. I can’t wait!!!

  9. Christina

    I made this yesterday for my husband’s birthday and it was HEAVEN!!! I had to use semi-sweet chocolate because I was out of dark but it came out great. I also made a vanilla bean buttercream because the hubs loves frosting, but it was divine. I love your recipes, always simple and delicious!

  10. Julie

    That looks sensational and so easy!!
    I just wondered though, do you think it would work as cupcakes?
    Same oven temp you think?
    I love your recipes :)

    Ok so I know you live in the south and I don’t know if they have Entenmenn’s baked goods there (?) but my favorite cake as a kid was this Entenmann’s moist chocolate cake with a marshmallow-y frosting and this looks just like it. I want some!!!
