Preheat the oven to 175°C. Grease a 23-centimetre flan pan and dust lightly with flour. In a mixing bowl, whisk eggs and sugar until pale and increased in volume. Gently fold in flour, cornstarch, and baking powder until just combined. Spread batter evenly into the prepared pan. Bake for 12 to 15 minutes until lightly golden and a toothpick inserted comes out clean. Let cool completely.

In a saucepan, heat milk until just below boiling. In a separate bowl, whisk together egg yolks, sugar, and cornstarch until smooth. Slowly whisk the hot milk into the egg yolk mixture. Return the mixture to the saucepan and cook over medium heat, stirring constantly, until thickened. Remove from heat and stir in vanilla extract. Allow custard to cool slightly before use.
