How to Make Lemon Custard Cake That Melts in Your Mouth

  1. Grease an 8×8-inch baking dish and line it with parchment paper. Preheat the oven to 325°F (160°C).

  4. Mix in the melted butter, lemon zest, and lemon juice until well combined.
  5. Sift in the flour and gently fold until the batter is smooth.
  6. Slowly whisk in the lukewarm milk. The batter will be quite thin at this point.
  7. Gently fold in the whipped egg whites in three parts, ensuring small lumps are okay.
  8. Pour the batter into the prepared dish and smooth out the top.
  9. Bake for 45–55 minutes, until the top is golden and the center is slightly jiggly.
  10. Cool the cake completely, then chill in the fridge for at least 1 hour before slicing.
  11. Dust with powdered sugar and garnish with lemon slices and mint leaves before serving.

Variations & Creative Twists

  • Berry Bliss: Add a handful of fresh blueberries or raspberries mixed into the batter for a delightful fruity twist.
  • Ginger Lemon: Incorporate some finely grated fresh ginger into the batter for a zesty and spicy variation.
  • Coconut Cream: Substitute half of the whole milk with coconut milk for a tropical flair. The nutty flavor complements the lemon beautifully.
  • Meringue Magic: Top the cake with a light meringue after it cools, then briefly broil for a golden finish.
