🛒 Ingredients

10 servings

10
  • 1½ packets of plain shortbread or digestive biscuits (about 300 g)
  • 120 g (½ cup) unsalted butter, melted
  • 11 Gala apples, peeled and grated
  • 9 tablespoons granulated sugar
  • 2 tablespoons ground cinnamon
  • 1 tablespoon fresh lemon juice
  • 1 can sweetened condensed milk (395 g / 14 oz)
  • 1 cup heavy cream or sour cream (200 g)
  • 4 egg yolks
  • vanilla extract or vanilla powder, to taste

Directions

  1. 1

    Blitz the biscuits in a food processor until fine crumbs form. Add the melted butter and pulse until the mixture holds together like damp sand.

  2. 2

    Press the mixture evenly into the base of a 26-28 cm springform pan. Refrigerate while you prepare the filling.

  3. 3

    Cook the grated apples, sugar, and lemon juice in a large saucepan over medium heat, stirring often, until all moisture has evaporated and the mixture is jammy (about 15 minutes).

  4. 4

    Stir in the cinnamon, remove from heat, and allow to cool completely. Spread evenly over the biscuit base.

  5. 5

    In a clean saucepan, whisk together the condensed milk, egg yolks, and vanilla. Cook over low heat, stirring constantly, until thickened. Remove from heat and fold in the cream.

  6. 6

    Pour the custard over the apple layer, smooth the top, and dust with extra cinnamon.

  7. 7

    Bake in a preheated oven at 180 °C (350 °F) for 20 minutes, until the custard is just set with a slight wobble.

  8. 8

    Cool to room temperature, then refrigerate for at least 2 hours before slicing and serving cold.

💡 Chef's Tip

For a firmer crust, blind-bake the biscuit base at 180 °C for 8 minutes before adding the apple filling. Granny Smith apples work beautifully here if you prefer a tart contrast to the sweet custard.
