Dark Chocolate Cake

This dark chocolate cake is incredibly moist with a rich, deep chocolate flavor. Topped with whipped buttercream, it’s a delicious treat.

Ingredients needed

  • Flour. 
  • Sugar. Granulated sugar or caster sugar can be used.
  • Salt. 
  • Baking powder. 
  • Baking soda/ bicarbonate of soda.
  • Cocoa powder. Use a good quality unsweetened cocoa powder. Dutch process cocoa is fantastic if you can find it.
  • Boiling water. I often add a tablespoon of espresso powder to the water but this is optional. You can use hot coffee as substitute for the water.
  • Milk. Buttermilk can also be used. If you want to keep this recipe dairy-free, use almond milk or coconut milk.
  • Vegetable oil. Any neutral oil will work. Canola oil, Avocado oil, Sunflower oil, Grapeseed oil etc.
  • Vanilla extract. 
  • Eggs. 
  • Dark chocolate.

For the buttercream:

I made a rich dark chocolate frosting to decorate the cake with but chocolate ganache, chocolate peanut butter frosting or cream cheese frosting will also work.

  • Butter. I used salted butter but unsalted butter can substituted.
  • Powdered sugar/Icing sugar. 
  • Cocoa powder. 
  • Dark chocolate.
  • Heavy cream / whipping cream.

How to make dark chocolate cake at home

  1. Make the batter: In a large mixing bowl, whisk the dry ingredients together. In a separate bowl, whisk together the milk, vegetable oil vanilla, eggs and melted dark chocolate. Pour the wet ingredients into the dry and then stir in until almost fully combined then pour in the boiling water and mix until a smooth batter forms.
  2. Bake: Grease and line a rectangular cake pan with parchment paper (or use any cake pans of your choice – this recipe will make two round layers or one sheet cake). Pour the cake batter into the prepared pan then place in the oven. Allow to bake for 30-40 minute or until a toothpick inserted comes out clean.
  3. Cool: Remove from the oven and allow to cool completely before removing from the pan.
  4. Make the chocolate buttercream: Beat the butter and sugar for 5 minutes on medium speed until light and fluffy. Scrape the bowl down with a spatula a few times while beating. Add the cocoa powder and beat in. Add the melted chocolate and cream and beat until smooth and creamy. Top the cooled cake with the chocolate frosting and spread with a spatula or spoon.
  5. Serve: Slice the cake into squares and serve.
