Instructions
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper for easy removal.
- In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined and free of lumps.
- In a separate bowl, mix the buttermilk, vegetable oil, eggs, and vanilla extract. Pour this mixture into the dry ingredients and beat on medium speed until just combined – about 2 minutes.
- Carefully stir in the boiling water. The batter will be thin – this is normal and will result in an incredibly moist cake.
- Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Cool in pans for 10 minutes before transferring to wire racks to cool completely.
- Beat the softened butter until creamy. Gradually add powdered sugar and cocoa powder, then mix in heavy cream, vanilla extract, and salt. Beat until light and fluffy.
- Once cakes are completely cool, frost the top of one layer, place the second layer on top, and frost the entire cake generously for that iconic Matilda look.
Notes
The boiling water helps 'bloom' the cocoa powder, intensifying the chocolate flavor and creating an exceptionally moist crumb. Ensure eggs and buttermilk are at room temperature for optimal mixing and texture. Don't overmix – mix just until ingredients are combined. Never frost a warm cake – wait until it's completely cool to prevent the frosting from melting.
