Ingredients

Scale
  • 1 ¾ cups (220 g) all-purpose flour, sifted
  • ¾ cup (75 g) unsweetened cocoa powder, preferably Dutch-processed
  • 1 ½ cups (300 g) granulated sugar
  • 1 ½ teaspoons baking soda
  • ½ teaspoon salt
  • 2 large eggs, room temperature
  • 1 cup (240 ml) dry red wine (Cabernet Sauvignon or Merlot recommended)
  • ½ cup (120 ml) vegetable oil
  • 2 teaspoons vanilla extract
  • ½ cup (120 ml) buttermilk, room temperature (optional but recommended)
  • 1 cup (240 ml) heavy cream, chilled
  • 6 oz (170 g) semisweet chocolate chips, melted and slightly cooled
  • 2 tablespoons powdered sugar
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour your cake pan(s) or line with parchment paper.
  2. In a large bowl, sift together flour, cocoa powder, sugar, baking soda, and salt. Whisk to combine.
  3. In a separate bowl, beat eggs lightly with red wine, vegetable oil, vanilla extract, and buttermilk (if using) until smooth and slightly frothy.
  4. Slowly pour wet ingredients into dry ingredients, stirring gently with a spatula until just combined. Do not overmix.
  5. Pour batter into prepared pan(s) and smooth the top. Tap the pan lightly to release air bubbles.
  6. Bake for 35–40 minutes for one 9-inch pan, or 25–30 minutes for two 8-inch pans. Check doneness with a toothpick.
  7. Let the cake cool in the pan for 15 minutes, then transfer to a cooling rack to cool completely.
  8. Whip chilled heavy cream in a cold bowl until soft peaks form. Gently fold in melted chocolate, powdered sugar, and vanilla extract until light and airy.
  9. Spread the mousse evenly over the cooled cake. Chill in the refrigerator for at least 1 hour to set.
  10. Slice with a warm knife and serve chilled or at room temperature.

Notes

Let red wine come to room temperature before mixing for better blending. Melt chocolate slowly to avoid burning. Fold mousse gently to keep it light and airy. Use a warm knife dipped in hot water for clean slices. Buttermilk is optional but recommended for tender crumb; can substitute with milk plus lemon juice or vinegar.
