Ingredients & Substitutions
All-Purpose Flour
You will need 1 1/4 cups (150g) of all-purpose flour in total, divided between the crust and the filling. It creates a tender but firm shortbread base and helps stabilize the custard.
Granulated Sugar
Using 1 5/6 cups (365g) total, the sugar sweetens the tart lemon profile. It creates a perfectly balanced filling that isn’t overly sour.
Unsalted Butter
You will need 1/2 cup (115g) of melted unsalted butter. This is the secret to achieving that undeniably buttery, golden-brown crust.
Large Eggs
Use 4 large eggs at room temperature. They are the structural backbone of the thick, creamy, pale yellow custard filling.
Fresh Lemon Juice & Zest
You need 1/2 cup (120ml) of freshly squeezed lemon juice and 2 tbsp (12g) of zest. Bottled juice will not give you the bright, natural flavor required for this dessert.
Heavy Cream
Using 1/2 cup (120ml) of heavy cream adds luxurious fat to the filling. This ensures the moist texture of the custard remains perfectly sliceable.
Kosher Salt
Just 1/4 tsp (1g) of salt in the crust elevates all the flavors. It cuts through the sweetness and enhances the buttery notes.
Powdered Sugar
You will need 2 tbsp (15g) of powdered sugar. This is used strictly for generously dusting the top of the cake before serving.
Equipment Needed
- 8-inch or 9-inch Springform Pan: Essential for cleanly removing the cake without damaging the delicate custard layers.
- Parchment Paper: Prevents the buttery crust from sticking to the bottom of the pan.
- Mixing Bowls & Whisk: Necessary for smoothly combining the custard ingredients without over-aerating the eggs.
- Fine Mesh Sieve: Optional, but recommended for straining the lemon juice to remove seeds and excess pulp.
Step-by-Step Instructions
Step 1: Prepare the Crust
Preheat your oven to 350°F (175°C). Line the bottom of your springform pan with parchment paper.
In a medium bowl, combine 1 cup (120g) of all-purpose flour, 1/3 cup (65g) of granulated sugar, the melted butter, and the salt. Stir until the mixture resembles wet sand.
Step 2: Bake to Golden-Brown
Press the crust mixture firmly and evenly into the bottom of the prepared pan. Bake for 15 to 18 minutes.
Watch for a crucial visual cue: the base should form a buttery, golden-brown crust. Remove it from the oven and let it cool slightly while you lower the oven temperature to 325°F (160°C).
Step 3: Whisk the Custard Filling
In a large mixing bowl, whisk together the remaining 1 1/2 cups (300g) of sugar and 1/4 cup (30g) of flour. Add the eggs one at a time, whisking gently until combined.
Pour in the fresh lemon juice, lemon zest, and heavy cream. Whisk until you have a smooth, thick, creamy, pale yellow custard filling.
Step 4: Bake the Cake
Carefully pour the liquid filling over the warm crust. Place the pan back into the oven and bake for 35 to 40 minutes.
You will know it is done when the top of the cake is lightly browned on the edges and the center still has a slight jiggle. Do not overbake, or you will lose the moist texture of the custard.
Step 5: Chill and Garnish
Allow the cake to cool completely at room temperature for 1 hour, then transfer it to the refrigerator to chill for at least 4 hours. This chilling process solidifies the filling for a clean slice.
Just before serving on a warm-toned wooden table or rustic white plate, generously dust the top with powdered sugar.
Expert Tips for Success
- Use Room Temperature Ingredients: Ensuring your eggs and heavy cream are at room temperature prevents the custard filling from separating or baking unevenly.
- Press the Crust Firmly: Use the flat bottom of a measuring cup to pack the crust down. This ensures the wet filling does not seep underneath while baking.
- Don’t Skip the Chill Time: Slicing into a warm custard cake will result in a runny mess. It must chill completely to achieve that thick, creamy consistency.
- Dust Just Before Serving: The moisture from the custard will eventually absorb the powdered sugar. For the best visual presentation, dust the cake right as it hits the plate.
Storage & Reheating/Freezing
Store leftover Lemon Custard Cake in the refrigerator. Cover the pan tightly with plastic wrap or transfer slices to an airtight container. It will keep its moist texture for up to 4 days.
You can freeze this cake, though the texture of the custard may change slightly upon thawing. Wrap individual slices in plastic wrap, then place them in a freezer-safe bag for up to 2 months. Thaw overnight in the fridge before serving, and add a fresh dusting of powdered sugar.

Frequently Asked Questions
Yes! In fact, making this cake a day ahead is ideal because it allows the custard ample time to chill and firm up in the fridge overnight. Wait to dust with powdered sugar until right before serving.
It is highly recommended to use fresh lemon juice. Bottled lemon juice often contains preservatives that can alter the natural tartness and prevent the custard from setting properly.
Yes, because the filling is made with eggs and heavy cream, the cake must be stored in the refrigerator. It will keep its moist texture and remain food-safe for up to 4 days.
Pre-baking the shortbread crust until it is a deep golden-brown creates a barrier. Make sure you press the crust firmly into the pan so the liquid custard doesn’t seep underneath during baking.
A runny custard usually means the cake was underbaked or it was not chilled long enough. The custard needs at least 4 hours in the refrigerator to fully set into a sliceable, thick texture.
