Billie Eilish’s Chocolate Cake Recipe!!!

My first recipe since the begining of spring!! This is to celebrate the one year anniversary of the best album ever made, that means the absolute world to me, Happier Than Ever by Billie Eilish. In the year that this album has existed, I’ve learned so much about music, cried to like every song, and got to have the best experience of my life seeing it performed live (03/25/22!) Basically everyone who knoes me knows that I’m 100% a Billie fan, most of my closest friends/family are giant fans too, but yeah. I love her so much that it actually hurts.

BUT. Something very cool about Billie is that she is vegan, and sometimes bakes (so we were absolutely made for each other) and a few weeks ago, she put on her Instagram story a photo of a chocolate frosting covered cake decorated with chocolate curls and chocolate covered strawberries. A lot of the time, she actually puts recipes for the things she makes, always vegan, and gluten free most of the time (I’m pretty sure) too. But with the photo of this cake, there was no recipe, which made her fandom kind of mad, so I took it upon myself to save the day with a vegan and easilly gluten free adaptation of the cake she posted!! Technically, we can’t know for sure that it was Billie Eilish who made that cake, but I trust that it was, and she at least ate it, so this cake is completely based off of and dedicated to her.

I’m releasing it today because it’s the anniversary of Happier Than Ever (HTE), which I wrote on one version of the cake I made. The other one was just a copy of the cake she posted (check out the gallery below to see all of them.) Also, obviously you don’t have to be a die hard Billie fan to make this cake!! It’s literally just a basic, vegan, very chocolaty cake with yummy frosting that’s absolutely perfect for summer picnics and celebrations of all kinds.

I’d love it so much if you’d try it, go check out my Instagram for the post, I have so much fun stuff coming up to end off this summer full of bakes, and hopefully soon I’ll finally post my official summer recipe. For now though, thank you so much for reading, this recipe was so fun to develop, eat, and write about, and I love you so so much!

Billie Eilish’s Chocolate Cake!!

This cake, based off of a cake that Billie Eilish posted on her Instagram story, is a vegan and easily gluten free fudgy and extremely chocolaty cake, with vegan chocolate American buttercream frosting, and decorated with chocolate curls and chocolate dipped strawberries.
Servings: 1 two layer cake


For the cake

  • 1 ¾ cups all-purpose flour (or gluten free all-purpose flour)
  • 1 ¼ cups sugar
  • 1 tsp baking powder
  • ½ tsp baking soda
  • 1 tsp salt
  • ¾ cup unsweetened cocoa powder
  • 1 cup non-dairy milk
  • 2 tbsp white or apple cider vinegar
  • ½ cup canola/vegetable oil
  • 1 tsp vanilla extract
  • 1 cup boiling water

For the frosting

  • 1 ½ cup vegan butter (very softened)
  • ½ cup cocoa powder
  • 2-2 ½ cups powdered sugar

For the chocolate dipped strawberries

  • ½ cup chocolate, melted
  • ~10 fresh strawberries


For the cake

  • Preheat oven to 350°F, grease two 8 inch (or smaller) cake pans with oil/butter and line with circles of parchment paper.
  • Whisk together flour, baking soda, baking powder, and salt in a large bowl. Sift in cocoa powder.
  • Whisk together milk, vinegar, oil, and vanilla in a small bowl or jug. Boil water.
  • Add the wet ingredients to the dry, and mix in hot water quickly, without overmixing.
  • Pour into prepared pans, bake for 30-35 minutes or until a toothpick comes out mostly clean and dry.
  • Let cool completely before decorating.

For the frosting

  • Soften your butter by leaving it out for a few hours or microwaving for about 10 seconds. Place it into the bowl of a hand or stand mixer.
  • Whip butter for at least a minute, scraping down the sides of your bowl and repeating a few times to make sure it's fluffy. Add in cocoa powder and whip for about 2 minutes.
  • Add in 1 cup of the powdered sugar, and whip for 2 more minutes, making sure to scrape down sides. Repeat, and if you want to make the buttercream stiffer, add up to ½ cup more powdered sugar and repeat again.
  • Whip for 3-5 minutes when your desired amount of powdered sugar has been added, then quickly put into the fridge.

For the chocolate dipped strawberries

  • Line a baking sheet with parchment paper or silpat, melt chocolate.
  • Dip strawberries one at a time in the chocolate, place on mat, and refrigerate until completely hardened.

To assemble/decorate!!

  • Cut off the domes on the tops of your cakes with a cerated knife. Take your frosting out of the fridge if it's gotten too hard.
  • Make chocolate curls, by using a vegetable peeler to shave a bar of chocolate, and store in the fridge.
  • Put one cake layer down on a flat surface, on top of a little glob of frosting so that it doesn't slide while decorating.
  • Use a palate or regular knife to take about a ½ cup of frosting and spread it between layers. Repeat on the top of the cake, then spread even more frosting, but not a ton, on the sides of the cake. Smooth completely and try to get all the crumbs sealed with this thin layer.
  • Refrigerate or freeze until you can touch the frosting and your finger is dry.
  • Cover the cake with the rest of the frosting, smooth or make ruffles on the sides like Billie did (see photo in blogpost), refrigerate or freeze again.
  • Cover the top of the cake with chocolate curls, and place 3 strawberries on the top of the cake, in the same way as Billie (see photo again)(or decorate however you want) Put strawberries on the bottom of the cake as well.
  • Enjoy!!
