  • 1/2 tsp salt
  • 1 cup (200 g) sugar
  • 365 ml (1 can) evaporated milk
  • 1/2 cup (115 g) butter or refrigerated margarine

Cake Layers:

  • 24 graham crackers
  • 3/4 cup (180 ml) evaporated milk

Chocolate Ganache:

  • 250 ml (1 cup) all-purpose cream
  • 250 g (8.8 oz) dark chocolate chips or bar, chopped

Directions

Prepare the Custard Filling:

  • In a medium saucepan, whisk together the egg yolks, vanilla extract, flour, salt, and sugar until smooth.
  • Gradually whisk in 365 ml evaporated milk, ensuring no lumps form.
  • Cook the mixture over medium heat, stirring constantly, until it thickens and comes to a gentle boil.
  • Remove from heat and stir in the butter or margarine until fully melted and incorporated.
  • Let the custard cool to room temperature, then chill in the refrigerator for about 1 hour.

Assemble the Cake:

  • Pour 3/4 cup of evaporated milk into a shallow dish. Briefly dip each graham cracker into the milk.
  • Layer the dipped graham crackers on the bottom of a 9×13 inch baking dish.
  • Spread half of the chilled custard evenly over the first layer of graham crackers.
  • Add another layer of dipped graham crackers, followed by the remaining custard.
  • Add a final layer of dipped graham crackers on top of the custard.

Prepare the Chocolate Ganache:

  • In a small saucepan, heat the all-purpose cream until it just begins to simmer (do not boil).
  • Remove from heat and add the dark chocolate chips or chopped chocolate bar. Let sit for a few minutes, then stir until smooth and glossy.

Finish the Cake:

  • Pour the ganache over the top layer of graham crackers, spreading it evenly with a spatula.
  • Refrigerate the cake for at least 4 hours, or overnight, to allow it to set.
