Ingredients

Scale

For the Cake

  • 1 1/2 cups all purpose flour
  • 1 cup granulated sugar
  • 3 large eggs
  • 1/2 cup unsalted butter, melted
  • 1 cup whole milk, divided
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon salt

For the Pastry Cream

  • 3 tablespoons cornstarch
  • 2 teaspoons vanilla extract, divided
  • 1/4 cup of the sugar from measured amount (extracted as 1 cup sugar total, 1/4 cup used here)

For the Ganache

  • 4 ounces semi sweet chocolate, chopped
  • 1/2 cup heavy cream

Instructions

  1. Preheat and Prepare Pan. Preheat oven to 350 degrees Fahrenheit. Grease and line a 9 inch round cake pan.
  2. Mix Dry Ingredients. In a bowl, whisk together flour, baking powder, and salt.
  3. Beat Eggs and Sugar. In a separate bowl, beat eggs and granulated sugar until light and slightly thickened.
  4. Add Wet Ingredients. Stir in melted butter, 1/2 cup of the milk, and 1 teaspoon vanilla extract.
  5. Combine Mixtures. Gradually mix the dry ingredients into the wet mixture until smooth.
  6. Bake. Pour batter into prepared pan and bake for 25 to 30 minutes until golden and a toothpick inserted in the center comes out clean.
  7. Cool and Slice. Cool completely, then slice the cake horizontally into two even layers.
  8. Make Pastry Cream. In a saucepan, whisk together remaining 1/2 cup milk, cornstarch, and 1/4 cup of the sugar from the measured amount. Cook over medium heat while whisking until thickened.
  9. Finish Pastry Cream. Remove from heat and stir in remaining 1 teaspoon vanilla extract. Let pastry cream cool completely.
  10. Assemble Cake. Spread pastry cream evenly over the bottom cake layer and place the top layer over it.
  11. Prepare Ganache. Heat heavy cream until warm but not boiling. Pour over chopped chocolate and let sit for 2 minutes, then stir until smooth to form ganache.
  12. Top and Chill. Pour ganache over the top of the cake and allow it to spread evenly. Chill for at least 1 hour before slicing and serving.

Notes

  • Cool the cake and pastry cream completely before assembling to ensure proper texture.
  • Chill the cake after topping with ganache for at least 1 hour to set the ganache perfectly.
