Equipment

  • medium sized saucepan
  • Whisk
  • medium bowl
  • 8" cake pan
  • large mixing bowl
  • Electric mixer
  • large glass measuring cup
  • Wire cooling rack
  • cake plate

Ingredients

For the cake

  • 2 eggs
  • 1 cup sugar
  • 1 cup + 2 tablespoons flour
  • ½ teaspoon salt
  • 1 ¼ teaspoon baking powder
  • 5 tablespoons butter
  • ½ cup whole milk
  • 2 teaspoons vanilla

For the filling:

  • 5 egg yolks
  • cup sugar
  • ¼ cup cornstarch
  • 2 cups whole milk
  • 1 tablespoons butter
  • 1 tablespoon vanilla

Chocolate Topping:

  • 6 ounces semi-sweet chocolate
  • ¼ cup heavy cream
  • ½ teaspoon vanilla

Instructions

  • Start with making the filling so it can chill. Heat the milk in a medium sized saucepan over low heat.
  • While it’s heating, whisk the egg yolks and sugar until smooth.
  • Add in the cornstarch and whisk.
  • Once the milk is simmering, slowly pour it into the eggs while whisking vigorously to prevent the eggs from curdling. Return the mixture to the saucepan and whisk over low/medium heat until it begins to thicken.
  • Remove from heat and add the butter and vanilla and stir until the butter has melted.
  • Place the filling into a bowl and cover with plastic wrap that’s been laid directly on top of the cream filling to prevent it from forming a skin.
  • Place in the refrigerator to chill thoroughly while making the cake.
  • Preheat the oven to 350 degrees. Spray an 8” cake pan with cooking spray containing flour and set aside.
  • In a large bowl, beat the eggs and sugar for 4 minutes. Really, set a timer!
  • Whisk the flour, salt and baking powder together. Add it to the egg mixture and beat until incorporated.
  • In a large glass measuring cup, heat the milk and butter together until the butter has melted.
  • Add the vanilla to the milk and stir. Gradually pour the milk/butter mixture into the batter and mix.
  • The batter will be quite thin. Pour into the cake pan and bake for 30-35 minutes, or until a skewer comes out cleanly. Remove and let cool in the cake pan for 10 minutes before turning out on a cooling rack and letting cool completely.
  • Once the cake has cooled, slice in half and stack the first layer on a cake plate and spread the cream filling over the entire layer.
  • Top with the remaining layer of cake and press down gently to set the top layer.
  • Return it to the refrigerator for about 30 minutes to set.
  • In a small (microwave safe) bowl, place the heavy cream and chocolate chips and melt in short intervals, stirring constantly until the chocolate is completely melted and smooth.
  • Stir in the vanilla.
  • Pour the chocolate over the top of the cake and using a spoon, push a little bit over the edges to let it drip down the sides slightly.
  • Return to the refrigerator for an additional 15-20 minutes to allow the ganache to set.
