For the Chocolate Ganache Topping
  • 1 cup 170g semi-sweet chocolate chips (or dairy-free chocolate)
  • ¾ cup 180ml heavy cream (or coconut cream for dairy-free)
  • 1 tsp vanilla extract

Equipment

  • Two 8-inch round cake pans
  • Parchment paper
  • Mixing bowls (large and medium)
  • Whisk or electric mixer
  • Measuring cups/spoons or kitchen scale
  • Cooling rack
  • Small saucepan (for ganache)

Method
 

Make the Cake
  1. Preheat oven to 350°F (175°C). Grease two 8-inch cake pans and line with parchment paper.
  2. In a large bowl, whisk gluten-free flour, cocoa powder, baking powder, baking soda, and salt.
  3. In a separate bowl, whisk eggs, granulated sugar, brown sugar, melted butter, buttermilk, and vanilla until smooth.
  4. Gradually add dry ingredients to wet, mixing until just combined. Slowly stir in hot water or coffee to form a smooth batter.
  5. Divide batter evenly between pans. Bake for 25–30 minutes, or until a toothpick comes out clean.
  6. Cool cakes in pans for 10 minutes, then transfer to a cooling rack.
Make the Ganache Topping
  1. Heat heavy cream in a saucepan over medium heat until just simmering (do not boil).
  2. Pour hot cream over chocolate chips in a heatproof bowl. Let sit for 2 minutes, then stir until smooth.
  3. Add vanilla extract. Let ganache cool slightly for pouring.
Optional Whipped Ganache
  1. Cool ganache to room temperature, then refrigerate for 20–30 minutes until thickened.
  2. Whip with an electric mixer on medium speed for 2–3 minutes until fluffy. Spread over cooled cake.

Flavor Tip: Add 1 tsp espresso powder to enhance chocolate flavor.
