Description

Topped with a silky, stable cream cheese chocolate frosting, it provides a sophisticated balance of moisture and flavor perfect for any celebratory occasion.
Ingredients
- Unsalted butter
- Extra virgin olive oil
- Buttermilk
- Egg whites
- Egg yolks
- Sugar
- All-purpose flour
- Cornstarch
- Baking powder
- Baking soda
- Sea salt
- Cream cheese
- Cocoa powder
- Powdered sugar
- Vanilla extract
Instructions
- Prepare your equipment. Position oven racks to the center, grease two 9-inch round cake pans, line with parchment, and flour the sides.
- Aerate egg whites. Whisk egg whites and 1/4 cup sugar until the mixture is glossy and holds stiff peaks.
- Emulsify wet ingredients. Whisk together buttermilk, melted butter, egg yolks, olive oil, and extract in a bowl until uniform.
- Combine dry base. Sift the flour, cornstarch, baking powder, baking soda, salt, and remaining sugar together to remove clumps.
- Incorporate liquids. Gently stir the buttermilk mixture into the dry ingredients until just combined without over-mixing.
- Bake the layers. Divide batter into pans and bake at 350°F / 176°C for twenty minutes, rotating pans halfway through.
- Cool the cakes. Rest cakes in pans for fifteen minutes before inverting onto a wire rack to cool completely.
- Prepare the frosting. Beat butter and cream cheese, then gradually add cocoa, powdered sugar, and buttermilk until spreadable.
- Assemble the cake. Trim cake domes to ensure flat layers, frost between the rounds, and cover the exterior with the remaining frosting.
Notes
- Ensure all dairy and egg components are at room temperature to prevent the butter from seizing during emulsification.
- Use a digital scale to measure flour precisely, as volume measurements are prone to inconsistencies.
- Test your chemical leaveners by adding a pinch to vinegar; if they fail to bubble, discard and replace them for proper lift.
- Chill the baked cake layers before frosting to simplify the assembly process and minimize surface tearing.
