Ingredients

Chocolate Cake:

  • 2 cups all purpose flour (260g), sifted
  • 1 1/2 tsp baking powder
  • 1 1/2 tsp baking soda
  • 1 cup granulated sugar (200g)
  • 2/3 cup light brown sugar (135g)
  • 1 tsp salt
  • 3 large eggs
  • ⅔ cup vegetable oil (133g)
  • 1/3 cup buttermilk (80g) – mix 1/3 cup whole milk (80g) + 1 tsp vinegar to make your own
  • 1 cup sour cream (240g)
  • 3/4 cup cocoa powder, Dutch Processed preferred (75g)  
  • 2 tsp instant coffee
  • 3/4 cup boiling water (180g)

Dark Chocolate Fudge Frosting:

  • 300g dark chocolate, chopped – I recommend 55-60% like this one
  • 1 1/4 cup heavy cream (300g)
  • 8 oz cream cheese, room temperature (226g)
  • 1/3 cup cocoa powder (33g)
  • 1 cup powdered sugar (100g)
  • 1/4 tsp salt

Instructions

Chocolate Cake:

  1. Preheat oven to 350F (no fan) and prepare 3 8″ pans with parchment paper and butter
  2. In a bowl, combine the flour, baking powder, baking soda, granulated sugar, light brown sugar and salt. Whisk together until no lumps remain
  3. In a separate bowl, whisk together the eggs, vegetable oil, buttermilk and sour cream until smooth
  4. Add the dry ingredients to the wet in 2 additions, and gently whisk and fold until they are just combined and no big lumps remain. Do not over-mix
  5. In a separate small bowl, add the cocoa powder and instant coffee. Pour over the boiling water and whisk until a smooth shiny mixture forms
  6. Pour the cocoa mixture onto the remaining batter, and gently fold until a chocolate cake batter forms
  7. Divide the batter evenly between the 3 prepared cake pans
  8. Bake for ~22-24 minutes until a toothpick inserted in the center comes out with light moist crumbs attached
  9. Let the cakes cool in the pans for 20 minutes, then carefully remove them and place on a wire rack. Let them cool completely (I recommend at least 1 hour)

Dark Chocolate Fudge Frosting:

  1. While the cakes cool, make the frosting. Add the dark chocolate and heavy cream to a microwave safe bowl. Microwave in 20 second increments, stirring in between, until the chocolate melts and a smooth, shiny ganache forms. Make sure there are no chocolate lumps in it. The ganache should be warm, not hot. Let it cool down for 5-10 minutes
  2. To a separate bowl, add the room temperature cream cheese and sift in the cocoa powder, powdered sugar and salt. Whisk on medium speed until the mixture becomes smooth and creamy (1-2 minutes). Scrape the bowl once or twice as you do this
  3. Pour in the warm ganache, and whisk on low speed for about 60-90 seconds until a smooth mixture forms. Scrape the bowl in the middle to ensure everything is well combined. Do not over-mix
  4. At this point, the frosting will be very soft and runny. Just cover the bowl and let it rest at room temperature for 20-30 minutes, and it should reach a firmer, spreadable consistency. I don’t recommend chilling this frosting in the fridge as it can easily become too firm. If that happens, remove about 1 cup and microwave it for 20 seconds or until runny, then slowly fold through the rest to make it softer

Assembly:

  1. Once the cakes and frosting have cooled down, it’s time to assemble
  2. Use a large serrated knife to carefully trim off the domes from the cakes
  3. Layer them on top of each other with a generous layer of the frosting in between (don’t be stingy!). Cover the cake with a thin layer of frosting (crumb coat) and refrigerate for 20 minutes. Then slather on the remaining frosting all over
  4. Serve & enjoy! This cake is best eaten at room temperature

Notes

  • Cocoa powder: If you can’t find Dutch processed cocoa powder, you may use natural, 100% unsweetened cocoa powder. If you want a deep, dark chocolate cake, you can also substitute 10g of the Dutch processed cocoa powder with 10g of Black cocoa powder
  • Sour cream: If you can’t find sour cream, you can try making it at home with my homemade sour cream recipe. Some readers have also had success with full fat yogurt
  • Chocolate for the frosting: This frosting recipe has been especially developed for dark chocolate and has a beautiful flavor which complements the cake. I recommend anywhere between 50-60% for the perfect sweetness and consistency. If you use a higher dark chocolate (e.g., 70-80%) for flavor preference, I recommend increasing the heavy cream to 1 1/2 cups (360g) – this will definitely be a dark frosting! On the flip-side, I do not recommend using milk chocolate as the frosting will not firm up properly. If you still want to use milk chocolate, reduce the heavy cream to 1 cup (240g)
  • Shiny frosting: As the chocolate in the frosting sets, it might start to look dull. Before serving, use a blow dryer at the lowest setting and gently wave it 1 foot away from the cake. This will warm up the frosting enough for it to become shiny!
  • Coffee: I do not recommend skipping the coffee as it enhances the chocolate flavor. You won’t taste it! However, if you have an intolerance, you may skip it
  • Storage: This cake is best eaten at room temperature, or even slightly warmed up in the microwave (by the slice). You can keep it in an airtight container in a cool place for 2-3 days. Any longer and transfer to the fridge for up to 1 week combined. If refrigerating, I recommend microwaving for 10-20 seconds before eating
  • Make ahead: You can prepare this cake in advance and keep it at room temperature (~70F) for 1-2 days! Just make sure it is properly covered. I let it chill for 15-20 minutes so the frosting sets, then wrap in cling wrap and keep at room temperature
