Ingredients
Scale
For the Shortcrust Base:
1½ cups all-purpose flour
¼ cup granulated sugar
Pinch of salt
½ cup unsalted butter, cold and cubed
1 egg yolk
2–3 tbsp cold water
For the Lemon Custard Filling:
1½ cups whole milk
¾ cup granulated sugar
3 large egg yolks
¼ cup cornstarch
Zest of 1 lemon
½ cup fresh lemon juice (about 2 lemons)
2 tbsp unsalted butter
1 tsp vanilla extract
Instructions
Make the Crust: In a bowl, mix flour, sugar, and salt. Cut in cold butter until the mixture is crumbly. Add egg yolk and cold water, stirring until dough forms. Press into a tart pan or square cake pan and chill for 20–30 minutes.
Pre-Bake the Crust: Preheat oven to 350°F (175°C). Prick the base with a fork and bake for 12–15 minutes until lightly golden. Let cool slightly.
Prepare the Lemon Custard: In a saucepan, whisk sugar, cornstarch, lemon zest, and yolks. Slowly add milk while whisking. Cook over medium heat until thickened. Remove from heat and stir in lemon juice, butter, and vanilla.
Bake the Cake: Pour custard into pre-baked crust. Bake for 25–30 minutes until just set but still slightly jiggly in the center. Cool completely before slicing.
