Method
- Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line with parchment circles.
- Cream butter, granulated sugar, and brown sugar until light and fluffy, about 3–5 minutes.
- Beat in eggs one at a time, then mix in vanilla extract until combined.
- In a saucepan, heat stout and cocoa powder until smooth. Let cool slightly.
- In another bowl, whisk buttermilk with vegetable oil.
- Whisk flour, baking soda, baking powder, and salt together in a separate bowl.
- Alternate adding dry mix with wet (stout mixture and buttermilk mixture) into butter mixture, beginning and ending with dry. Mix until just combined.
- Fold in chopped dark chocolate gently.
- Divide batter into pans and bake 30–35 minutes. Let cool 10 minutes, then turn out onto racks.
- Make ganache by heating cream, pouring over chopped chocolate. Add butter and salt, whisk until smooth. Let cool until spreadable.
- Optional: For caramel, melt sugar until amber, stir in butter, cream, and salt. Let cool slightly before drizzling.
- Assemble by leveling cakes, spreading ganache between and over, then drizzle with caramel. Sprinkle sea salt. Serve!
Notes
You can prepare the ganache and caramel a day ahead. The cake also freezes well. Just wrap each layer tightly in plastic wrap and freeze for up to 2 months. Thaw before assembling. Optional salted caramel adds indulgent depth!
