Step‑by‑Step Instructions for Lemon Custard Cake
Step 1: Prepare the Crust
In a mixing bowl, combine the all-purpose flour, sugar, and salt, stirring gently to blend. Then, cut in cold unsalted butter with a pastry cutter or your fingertips until the mixture resembles coarse crumbs. Add the egg yolk and cold water gradually, mixing until a dough forms. Chill the dough in the refrigerator for 20-30 minutes to firm up.
Step 2: Pre-bake the Crust
Preheat your oven to 350°F (175°C) to prepare for baking. Roll out the chilled dough on a floured surface until about 1/4 inch thick, then fit it into a tart pan, ensuring to press it firmly into the edges. Prick the bottom with a fork to prevent bubbling and bake for 12-15 minutes, until the crust is golden and slightly firm. Let it cool completely.
Step 3: Make the Custard
In a medium saucepan, whisk together the sugar, cornstarch, lemon zest, and egg yolks until smooth. Gradually pour in the milk while stirring continuously to prevent lumps. Cook the mixture over medium heat, stirring frequently, until it thickens and starts to bubble, which should take about 8-10 minutes. Once thickened, mix in fresh lemon juice, butter, and vanilla extract until smooth.
Step 4: Bake the Cake
Pour the luscious lemon custard into the prepared crust, ensuring an even layer. Carefully place it in the oven and bake for 25-30 minutes. The custard should appear set but with a slight jiggle in the center when done. Remove the cake from the oven and allow it to cool completely before slicing for serving.

How to Store and Freeze Lemon Custard Cake
Refrigerator: Store leftover slices tightly wrapped in plastic wrap or an airtight container for up to 3 days to maintain freshness and flavor.
Freezer: For longer storage, slice the Lemon Custard Cake and individually wrap portions in plastic wrap, then place them in a freezer bag. This method preserves taste for up to 3 months.
Thawing: When ready to enjoy, transfer the wrapped slices from the freezer to the fridge to thaw overnight or on the counter for a couple of hours before serving.
Reheating: If you would like to warm the cake slightly, do so in a low oven (about 300°F), just until warmed through, avoiding the microwave to maintain custard texture.
