Ingredients
For the Cake
- 1/2 cup unsalted butter (softened)
- 1 cup granulated sugar
- 3 large eggs
- 1 tablespoon lemon zest (from about 1 lemon)
- 1/4 cup fresh lemon juice
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
For the Custard Layer
- 2 cups whole milk
- 1/2 cup granulated sugar
- 3 large eggs
- 1/4 cup fresh lemon juice
- 1 tablespoon lemon zest
- 1 teaspoon vanilla extract
- 1/4 cup cornstarch
Timing
Making The Best Lemon Custard Cake takes about 20 minutes for preparation and 40-45 minutes for baking.
Instructions
Step 1: Preheat the Oven
- Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan and line the bottom with parchment paper for easy removal.
Step 2: Prepare the Cake Batter
- Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Add Eggs and Flavorings: Beat in the eggs one at a time, mixing well after each addition. Add the lemon zest, lemon juice, and vanilla extract, and mix until combined.
- Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.
- Pour into Pan: Pour the cake batter into the prepared cake pan and spread it evenly.
Step 3: Prepare the Custard Layer
- Heat Milk: In a medium saucepan over medium heat, combine the whole milk and sugar. Heat until the sugar dissolves and the mixture is warm, but do not boil.
- Mix Eggs and Cornstarch: In a separate bowl, whisk together the eggs, lemon juice, lemon zest, vanilla extract, and cornstarch until smooth.
- Combine Mixtures: Slowly pour the warm milk mixture into the egg mixture while whisking continuously to temper the eggs. This prevents them from curdling.
- Pour Custard Over Cake: Carefully pour the custard mixture over the cake batter in the pan. Do not stir; the custard will settle to the bottom during baking.
Step 4: Bake
- Bake: Bake in the preheated oven for 40-45 minutes, or until the top is lightly golden and the custard is set. A toothpick inserted into the center should come out clean.
- Cool: Remove from the oven and allow to cool in the pan for about 10 minutes before transferring to a wire rack to cool completely.
Step 5: Serve
- Dust with Powdered Sugar: Once cooled, dust the top with powdered sugar for an elegant finish.
- Slice and Enjoy: Serve slices of the cake chilled or at room temperature, and enjoy the delightful lemon flavor!
