Moist, rich chocolate cake layered with a glossy, silky chocolate fudge frosting. Just like the iconic cake from Matilda.
2 ½ cups all-purpose flour
1 ¾ cups granulated sugar
2 tsp baking powder
1 tsp baking soda
½ tsp kosher salt
½ cup cocoa powder (unsweetened)
⅔ cup vegetable oil
1 tsp vanilla extract
3 large eggs
⅔ cup buttermilk
1 cup hot coffee
11.11 oz unsalted butter
14.1 oz dark chocolate (60–70%), chopped
⅓ cup cocoa powder
1 ⅓ cups heavy cream
1 ⅓ cups powdered sugar
½ tsp kosher salt
1 tsp vanilla extract
Preheat oven to 350°F (180°C). Line two 8-inch cake pans with parchment paper and grease the sides.
In a large bowl, combine:
flour
sugar
salt
baking powder
baking soda
Sift in cocoa powder, then whisk to combine.
Add vegetable oil, buttermilk, vanilla, and eggs. Mix until almost combined.
Pour in the hot coffee and whisk until the batter is smooth and runny.
Divide batter between the two pans (using a scale works best for even layers). Optional: use cake strips for flat, even baking.
Bake for 25–30 minutes, or until a toothpick comes out clean.
Let cakes cool completely before frosting.
In a saucepan, add:
butter
heavy cream
dark chocolate
Sift in cocoa powder and powdered sugar. Add salt.
Cook over medium-high heat, stirring constantly, until completely smooth.
Strain mixture into a bowl (this makes it silky).
Cover the surface directly with plastic wrap to prevent a skin from forming.
Cool 30 minutes at room temperature, then chill 1–2 hours until thickened to frosting consistency.
Place a small dollop of frosting on your cake board or plate (to keep the cake from sliding).
Lay down the first cake layer.
Spread ⅓ of the frosting over the top.
Add the second cake layer.
Frost the outside with remaining frosting, using an offset spatula to create waves or swirls.
Chill 30 minutes before slicing for cleaner cuts.
