This decadent chocolate coconut cake recipe is topped with a creamy coconut marshmallow sauce and finished off with a layer of chocolate frosting. My husband’s absolute favorite cake!

If you’re a chocolate lover, you’ll most definitely enjoy this cake. It’s loaded with different flavors and textures and is a unique addition to any celebration. Looking for more chocolate recipes? Try my brownie pizza and chocolate pudding cake.

I started making this chocolate coconut cake years ago when I first learned to cook. I’ve adapted the recipe over time and can confidently say that if you’re a coconut fan, you will love this cake. My husband asks for this cake every year for his birthday, he can’t be swayed by the pretty pictures of other cakes I show him in magazines or on Pinterest. He’s declared this one to be his favorite.

How do you make chocolate coconut cake?

This chocolate coconut cake starts with a single layer of chocolate cake. But no one’s that excited by a plain, unadorned piece of chocolate cake. It’s the coconut sauce that makes this one special.

When you melt marshmallows with a little milk and sugar and add coconut to the mix, something really magical happens. It forms this thick and creamy sauce which then gets spread over the cake. The sauce firms up as it cools, which means it won’t run all over the place when you cut the cake. The final touch is a layer of chocolate frosting that gets poured over the top.

The cake is pretty straightforward to make – the one thing I want to mention is that the chocolate frosting is almost like a really thick glaze. It’s best to pour it evenly over the top rather than spread it with a knife, because as it cools it will not spread smoothly. To get a nice glossy coating like in my pictures, pour it and then don’t touch it again!

Whether you’re celebrating a birthday or just want a sweet treat to serve after dinner, no one can ever turn down a slice of cake. This chocolate coconut cake is the perfect all-occasion treat! Or in my case, the perfect annual birthday treat for my husband.

Ingredients

For the chocolate cake:

  • 1 box devil's food cake mix
  • oil, eggs and water as directed on cake mix package
  • cooking spray

For the coconut sauce:

  • 3/4 cup milk
  • 3/4 cup granulated sugar
  • 15 large marshmallows
  • 3 cups flaked sweetened coconut
  • 3/4 teaspoon cornstarch

For the chocolate frosting:

  • 3 tablespoons butter
  • 6 tablespoons granulated sugar
  • 4 1/2 tablespoons cocoa powder sifted
  • 4 1/2 tablespoons milk
  • 2 and 1/2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1/2 cup chocolate sprinkles

Instructions

  • For the cake: Coat a 9"x13" pan with cooking spray. Prepare the cake mix with the oil, eggs and water in amounts as directed on the box and bake according to package instructions. Cool completely in the pan.
  • For the coconut sauce: Combine milk, sugar and marshmallows in a medium saucepan, cook over medium heat for 5 minutes or until the marshmallows are melted.
  • Stir in coconut and cornstarch, bring to a boil. Cook one minute, stirring constantly. Remove from heat and pour the coconut sauce over the cake while it's still warm, then let cool completely before you add the frosting.
  • For the frosting: Melt butter in a small, heavy saucepan over low heat. Add granulated sugar, milk and cocoa powder, cook for 2-3 minutes or until mixture is thoroughly combined.
  • Remove from heat and cool slightly. Stir in powdered sugar and vanilla. Pour over the cake. Add the sprinkles on top while the frosting is still warm. Do not try to spread the frosting with a knife or it will not set properly.

Notes

Make Ahead: The entire cake can be made a day in advance.
Little Helpers: Sprinkle time! Let your kids do the decorating

      Hello Sara! Great to have connected on Facebook and to have spoken to you. 🙂 You KNOW I just love your site — I think this is my…. I’m not sure how many times I’ve commented. ANYWAY, You had me at chocolate, then you had me again at marshmallows, and then you just make me want to break into the zoo, free all the animals, and then sit down like a deviant and make myself one of these as the cops come to arrest me. And I’ll tell them “Arrest me? I’m ALREADY arrested — arrested by the flavors of this dessert, that is!” They’d look at me strange and I’ll smile with chocolate still in my teeth.

      This is how awesome this recipe is! THANKS FOR ZE AMAZINGNESS! <3

              Hi, just made this cake and when I made the icing, did exactly as you showed. Took off burner and waited a minute to cool slightly. When I added the powdered sugar it seized up. I had to add a few splashes of milk to loosen it up. Did you put powdered sugar in while still hot? I really only waited at most 30 to 45 seconds. It turned out, but not as liquid as yours was. Hoping it tastes good as I am taking it to a family party tomorrow. Thanks!!

            • Sara says

              September 7, 2018 at 11:00 pm

              Yes I add the sugar when it’s hot, powdered sugar contains corn starch so it will naturally thicken when it touches liquid. It’s totally fine to add a little more liquid, I hope your family enjoys it!
