Ingredients
Lemon Custard Filling
- 1 egg (for richness and body)
- 50 g sugar (for gentle sweetness)
- A pinch of salt (to highlight the flavors)
- 20 g cornstarch (for a smooth, thick custard)
- 200 ml milk (creates a velvety texture)
- Zest of 1 lemon (fresh, aromatic citrus notes)
- Juice of ½ lemon (adds a bright tang)
- 25 g butter (for a glossy, rich finish)
Cake Batter
- 2 eggs
- 100 g sugar (sweet but well balanced)
- 100 ml vegetable oil (keeps the crumb moist and tender)
- 120 ml milk (for a silky, pourable batter)
- Zest of 1 lemon (extra lemon flavor)
- Juice of 1 lemon (for a fresh, zesty kick)
- 200 g all‑purpose flour (provides structure and softness)
- 10 g baking powder (helps the cake rise and stay fluffy)
Step-by-Step Instructions
1. Prepare the Lemon Custard
- In a small saucepan, whisk together the egg, sugar, salt, and cornstarch until no lumps remain.
- Gradually pour in the milk while whisking continuously to keep the mixture smooth.
- Add the lemon zest and lemon juice.
- Cook over medium‑low heat, stirring constantly, until the custard thickens and gently bubbles, about 5 minutes.
- Remove from the heat, add the butter, and stir until completely melted and the custard is silky.
- Press a piece of plastic wrap directly onto the surface of the custard to prevent a skin from forming. Let it cool to room temperature.
2. Make the Cake Batter
- In a mixing bowl, beat the eggs and sugar together until the mixture becomes pale and airy.
- Slowly mix in the vegetable oil, milk, lemon zest, and lemon juice until fully combined.
- Sift the flour and baking powder over the wet ingredients.
- Gently fold everything together just until no streaks of flour remain. Avoid overmixing to keep the cake light and soft.
3. Assemble and Bake
- Preheat your oven to 350°F (175°C).
- Grease a 9‑inch (23 cm) round cake pan.
- Pour half of the cake batter into the prepared pan and smooth the surface.
- Spread the cooled lemon custard evenly over the batter, leaving a small border around the edges if possible.
- Cover the custard with the remaining cake batter, spreading it carefully so the custard stays mostly in the center.
- Bake for 30–35 minutes, or until the top is golden and a toothpick inserted into the cake portion comes out clean.
4. Cool and Finish
- Let the cake cool in the pan for a short time before carefully removing it.
- Once slightly cooled, dust the top with powdered sugar for a simple, elegant look.
- Slice and serve while still warm for the dreamiest, custardy texture.
