Equipment

  • bundt pan
  • Mixing bowls
  • Electric mixer
  • Measuring cups and spoons
  • wire cooling rack

Ingredients
  

  • 2 cups all-purpose flour
  • 1 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup unsweetened cocoa powder
  • 1 3/4 cups granulated sugar
  • 1 cup unsalted butter, softened
  • 3 large eggs
  • 2 tsp vanilla extract
  • 1 cup buttermilk
  • 1 cup heavy whipping cream
  • 1/2 cup cream cheese, softened
  • 1/2 cup powdered sugar
  • 1 tsp vanilla extract (for mousse)
  • 1 cup semi-sweet chocolate chips
  • 3/4 cup heavy cream (for ganache)

Instructions
 

  • Preheat the oven to 350°F (175°C). Grease and flour a bundt pan thoroughly.
  • In a large bowl, whisk together flour, baking powder, baking soda, salt, and cocoa powder.
  • In another bowl, beat butter and sugar until light and fluffy, about 3–5 minutes.
  • Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
  • Alternate adding dry ingredients and buttermilk to the batter, mixing gently until smooth.
  • Beat cream cheese and powdered sugar until smooth. Fold in vanilla and whipped cream until light and fluffy.
  • Pour half the cake batter into the pan, spread mousse evenly over the batter, then top with remaining batter.
  • Bake for 45–50 minutes or until a toothpick inserted comes out clean.
  • Heat heavy cream until just simmering, pour over chocolate chips, let sit 2 minutes, then whisk until smooth.
  • Pour ganache over the cooled cake and garnish with chocolate curls if desired.

Notes

Use room-temperature ingredients for best texture. Cool the cake completely before glazing with ganache. Store leftovers in an airtight container in the refrigerator for up to 3 days. The cake tastes even better after chilling overnight.
