- ¼ cup fresh lemon juice (from 1–2 lemons)

Instructions
1. Prepare the Cake
- Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan.
- In a medium bowl, whisk together the flour, baking powder, and salt.
- In a large bowl, cream the softened butter and sugar until light and fluffy.
- Add eggs one at a time, beating well after each.
- Mix in vanilla extract and lemon zest.
- Alternate adding the dry ingredients and milk to the wet mixture, stirring just until combined.
- Pour the batter into the prepared pan and smooth the top.
- Bake for 25–30 minutes or until a toothpick comes out clean.
- Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool fully.
2. Make the Lemon Custard
- In a saucepan over medium heat, combine milk and sugar. Stir until the sugar dissolves.
- In a separate bowl, whisk together egg yolks and cornstarch.
- Slowly add a bit of the warm milk mixture into the yolks, whisking constantly to temper.
- Pour the tempered yolk mixture back into the saucepan.
- Cook over medium heat, stirring continuously, until thickened (about 5–7 minutes).
- Remove from heat and stir in lemon juice, zest, and vanilla.
3. Assemble the Cake
- Slice the cooled cake in half horizontally.
- Spread half the custard over the bottom layer.
- Place the top layer on and spread the remaining custard over the top.
- Chill for 1–2 hours before serving for best flavor and texture.
