Ingredients

  • All-purpose flour – 1 ½ cups (190g), sifted
  • Granulated sugar – 1 cup (200g)
  • Baking powder – 1 ½ tsp
  • Salt – ¼ tsp
  • Unsalted butter – ½ cup (113g), softened
  • Large eggs – 3, room temperature
  • Whole milk – ½ cup (120ml)
  • Pure vanilla extract – 2 tsp
  • Whole milk – 2 cups (480ml) for custard
  • Granulated sugar – ½ cup (100g) for custard
  • Egg yolks – 4 large
  • Cornstarch – ¼ cup (30g)
  • Unsalted butter – 2 tbsp (28g), room temperature for custard
  • Pure vanilla extract – 1 tsp for custard
  • Semisweet chocolate chips – ½ cup (90g)
  • Heavy cream – ¼ cup (60ml)
  • Unsalted butter – 1 tbsp (14g), optional for glaze

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line with parchment paper.
  2. In a medium bowl, whisk together flour, sugar, baking powder, and salt.
  3. In a large bowl, beat softened butter until creamy. Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
  4. Alternate adding dry ingredients and milk to the butter mixture, beginning and ending with dry ingredients. Mix on low speed until combined.
  5. Divide batter evenly between pans and smooth tops. Bake 25-30 minutes or until a toothpick comes out clean.
  6. Cool cakes in pans for 10 minutes, then transfer to a cooling rack to cool completely.
  7. For custard: Heat milk in a saucepan over medium heat until steaming but not boiling.
  8. Whisk egg yolks, sugar, and cornstarch in a bowl until smooth and pale.
  9. Temper eggs by slowly adding about ¼ cup hot milk while whisking constantly, then return mixture to saucepan with remaining milk.
  10. Cook over medium heat, whisking constantly until thickened (5-7 minutes). Remove from heat and stir in butter and vanilla extract. Strain if desired.
  11. Cover custard with plastic wrap pressed on surface and chill for about 1 hour.
  12. For glaze: Heat heavy cream until simmering, pour over chocolate chips, let sit 1-2 minutes, then stir until smooth. Stir in butter for shine.
  13. Assemble cake by placing one cake layer on plate, spreading custard evenly over it, then topping with second cake layer.
  14. Pour chocolate glaze over top and spread gently, allowing some to drip down sides.
  15. Chill assembled cake for at least 30 minutes before slicing and serving.

Notes

Temper eggs slowly by adding warm milk bit by bit to avoid curdling. Do not overmix cake batter to keep it tender. Pour chocolate glaze while warm for a shiny finish. Chill assembled cake before serving for best slicing.
