Equipment

  • Two 9-inch round cake pans
  • Mixing bowls
  • Electric mixer (notes: stand or hand mixer)
  • Measuring cups and spoons
  • Wire rack (notes: for cooling)
  • Offset spatula (notes: for spreading ganache)

Ingredients
  

  • For the Cake:
  • 2 cups All-purpose flour
  • 1 tablespoon Baking powder
  • 1/2 teaspoon Salt
  • 3/4 cup Unsalted butter notes: softened
  • 1 1/2 cups Granulated sugar
  • 3 Eggs
  • 1 tablespoon Vanilla extract
  • 1 cup Whole milk
  • For the Custard Filling:
  • 2 cups Whole milk
  • 1/2 cup Granulated sugar
  • 3 Egg yolks
  • 1/4 cup Cornstarch
  • 1 tablespoon Vanilla extract
  • For the Ganache:
  • 6 oz Chocolate chips notes: dark or semi-sweet
  • 1/2 cup Heavy cream
  • 1 tablespoon Unsalted butter notes: optional for shine

Instructions
 

  • Prepare the Cake Layers:
  • Preheat oven to 350°F. Grease and line two 9-inch cake pans.
  • In a mixing bowl, cream butter and sugar until fluffy. Add eggs one at a time, followed by vanilla extract.
  • In a separate bowl, whisk together flour, baking powder, and salt. Gradually add dry ingredients to the wet mixture, alternating with milk.
  • Pour batter evenly into prepared pans. Bake for 25-30 minutes or until a toothpick comes out clean. Let cool completely.
  • Make the Custard Filling:
  • Heat milk in a saucepan until warm but not boiling. In a bowl, whisk egg yolks, sugar, and cornstarch.
  • Slowly add warm milk to the egg mixture while whisking. Return to saucepan and cook over medium heat, stirring constantly until thickened. Add vanilla and let cool.
  • Prepare the Ganache:
  • In a saucepan, heat cream until it simmers. Remove from heat and stir in chocolate chips until smooth. Add butter if desired for extra shine.
  • Assemble the Cake:
  • Level the cake layers if needed. Place one layer on a serving plate and spread custard evenly on top. Add the second layer.
  • Pour ganache over the top, letting it drip down the sides. Smooth with an offset spatula. Chill for at least 1 hour before serving.

Notes

Refrigerate leftovers for up to 5 days. Let the cake sit at room temperature for 30 minutes before serving for the best texture.
