How to Make Italian Lemon Custard Cake
Step 1: Prepare the Custard
-
In a small saucepan, whisk milk, cornflour, sugar, and egg yolk.
-
Cook on low heat, stirring continuously until thick.
-
Remove from heat, stir in butter, lemon zest, and lemon juice.
-
Let the custard cool slightly.
Step 2: Make the Cake Batter
-
In a bowl, whisk eggs and sugar until pale and creamy.
-
Add melted butter, vanilla, lemon zest, and lemon juice.
-
Mix flour, baking powder, and salt. Add to the wet mixture.
-
Finally, pour in milk and whisk until smooth.
Step 3: Assemble and Bake
-
Pour cake batter into a greased baking pan.
-
Gently spoon custard over the batter. It will sink slightly while baking—this is what creates the creamy middle layer.
-
Bake at 350°F (175°C) for 35–40 minutes, or until the top turns golden and the center is set.
-
Let it cool completely before slicing—this helps the custard settle.
Serving Suggestions
-
Dust with powdered sugar for a classic finish.
-
Serve slightly chilled for the best custard texture.
-
Pair with coffee, espresso, or herbal tea.
-
Add fresh berries or a dollop of whipped cream for extra luxury.

Lighter cake: Replace half the butter with oil.

Different citrus: Try orange or lime for a twist.

Gluten free: Substitute with gluten-free all-purpose flour.
