Step‑by‑Step Instructions for Lemon Custard Cake
Step 1: Prepare the Crust
In a mixing bowl, combine all-purpose flour, granulated sugar, and a pinch of salt. Cut in cold butter using a pastry cutter or your fingers until the mixture resembles coarse sand. Stir in an egg yolk and add cold water, one tablespoon at a time, until a dough forms. Wrap the dough tightly in plastic and chill in the refrigerator for 20-30 minutes.
Step 2: Bake the Crust
Preheat your oven to 350°F (175°C). Roll out the chilled dough on a lightly floured surface, then gently press it into the bottom and up the sides of a tart or cake pan. Prick the bottom with a fork to prevent bubbling. Bake for 12-15 minutes, or until the crust is lightly golden. Allow it to cool completely in the pan.
Step 3: Make the Custard
In a medium saucepan, whisk together granulated sugar, cornstarch, lemon zest, and egg yolks until smooth. Gradually whisk in the milk, ensuring there are no lumps. Cook this mixture over medium heat, stirring constantly, until it thickens and starts to bubble—about 5-7 minutes. Remove from heat, then mix in fresh lemon juice, butter, and vanilla extract until fully combined.
Step 4: Combine and Bake
Pour the luscious custard into your cooled crust, smoothing it out with a spatula. Bake the assembled Lemon Custard Cake in the oven for 25-30 minutes, or until the edges are set while the center has a slight jiggle. This balances perfectly between creamy and set, creating that desired texture.
Step 5: Cool and Serve
Remove the cake from the oven and let it cool completely at room temperature. Once cooled, slice into squares or wedges, dust with powdered sugar, and garnish with fresh lemon twists or berries if desired. This delightful Lemon Custard Cake is best enjoyed chilled, allowing all those vibrant flavors to shine!
