Ingredients
- 40g unsweetened cocoa powder
- 240ml boiling water or hot coffee
- 360g all-purpose flour
- 240ml vegetable oil
- 240ml buttermilk
- Large eggs
- Vanilla extract
- Granulated sugar
- Baking soda
- Baking powder
- Salt
- 340g unsalted butter
- Confectioners’ sugar
- Fresh strawberries, finely chopped
- 98g semi-sweet chocolate bar
- Heavy cream
Instructions
- Preheat oven to 350°F (175°C) and prepare three 9-inch round cake pans with butter and parchment paper.
- Sift cocoa powder into a heat-proof bowl, whisk in boiling water or hot coffee until smooth, and let rest for 10 minutes.
- In a large bowl, whisk together flour, sugar, baking soda, baking powder, and salt for 60 seconds to ensure even distribution.
- Whisk the oil, room-temperature buttermilk, eggs, and vanilla into the cooled cocoa mixture until emulsified.
- Slowly pour the wet mixture into the dry ingredients, whisking until just uniform, then divide into pans.
- Bake for 30 minutes until springy, then cool completely before preparing the strawberry buttercream by beating butter, sugar, and berries.
- Assemble the cake with buttercream layers, chill for one hour, and finish with a ganache drip made from heated cream and chopped chocolate.
Notes
To achieve perfectly level cake layers without domes, consider using water-soaked fabric baking strips around the exterior of your pans. Always ensure your eggs and buttermilk are at true room temperature to prevent the batter from seizing and becoming dense.
