  • 1 tsp vanilla extract
  • 1/2 cup unsalted butter, melted
  • 1/2 cup milk

For the Three Milk Soak:

  • 1/2 cup whole milk
  • 1/2 cup evaporated milk
  • 1/2 cup sweetened condensed milk

For the Neapolitan Flan Filling:

  • 1 1/2 cups whole milk
  • 1 cup heavy cream
  • 3/4 cup sugar
  • 3 large eggs
  • 1 tsp vanilla extract
  • 2 tbsp cornstarch
  • 1/4 cup cocoa powder (for chocolate layer)
  • 1/4 cup strawberry puree (for strawberry layer)

For the Whipped Cream Topping:

  • 1 cup heavy cream
  • 2 tbsp powdered sugar
  • 1 tsp vanilla extract

Instructions

  1. Prepare the Sponge Cake:

    • Preheat oven to 350°F (175°C). Grease and flour an 8-inch round pan.
    • Sift flour, baking powder, and salt.
    • Beat eggs with sugar until fluffy (~5 mins). Mix in vanilla.
    • Fold in dry ingredients, then gently stir in melted butter and milk.
    • Pour into pan and bake for 25–30 mins. Cool for 10 mins, then transfer to a wire rack.
  2. Make the Milk Soak:

    • Mix whole milk, evaporated milk, and sweetened condensed milk. Set aside.
  3. Create the Neapolitan Flan Filling:

    • Heat milk, cream, and sugar until warm.
    • Whisk eggs and cornstarch. Slowly combine with warm milk mixture.
    • Return to heat and whisk until thickened (~5–7 mins).
    • Divide into 3 parts: leave one plain, add cocoa to one, strawberry puree to the other. Cool.
  4. Assemble the Cake:

    • Slice sponge cake horizontally into two layers.
    • Pour milk soak over both layers, letting it absorb for 5–10 mins.
    • Place bottom layer on serving plate, spread alternating flan layers. Top with second cake layer and remaining flan.
  5. Whipped Cream Topping:

    • Beat cream, powdered sugar, and vanilla until stiff peaks form.
    • Frost the cake and decorate as desired.
  6. Chill & Serve:

    • Refrigerate for 3–4 hours. Serve chilled, optionally with grated chocolate or fresh fruit.

Notes

  • For firmer flan, refrigerate it before layering.
  • A serrated knife helps neatly slice soaked sponge layers.
  • Use stabilized whipped cream if preparing ahead.
