Step-by-Step Instructions

1 – Prepare the Lemon Custard

1️⃣ In a saucepan, whisk together egg yolks, sugar, cornstarch, and milk until smooth.
2️⃣ Cook over medium heat, whisking constantly, until thickened.
3️⃣ Remove from heat and stir in butter, lemon juice, and zest.
4️⃣ Set aside to cool.

2 – Make the Cake Batter

1️⃣ In a large bowl, beat eggs and sugar until light and frothy.
2️⃣ Add melted butter, milk, vanilla, and lemon zest.
3️⃣ Sift in flour, baking powder, and salt. Mix until smooth.

3 – Combine and Bake

1️⃣ Pour half of the batter into a greased 9-inch baking pan.
2️⃣ Spoon the lemon custard evenly over the layer.
3️⃣ Top with the remaining batter — don’t worry if it doesn’t cover perfectly.
4️⃣ Bake at 350°F (175°C) for 35–40 minutes, until golden and just set.

4 – Cool and Dust

Cool completely before dusting with powdered sugar. Slice gently — the custard layer should be creamy and slightly wobbly.

What Is an Italian Lemon Cake?

An Italian Lemon Cake is a classic European-style dessert known for its light sponge texture and bright citrus flavor.
Unlike heavy American cakes, Italian versions rely on eggs, milk, and zest for flavor rather than frosting.

This variation — Lemon Custard Cake — adds a middle layer of creamy custard that forms naturally during baking, creating two distinct textures: a fluffy top and a silky custard base.

Do Italian Cream or Custard Cakes Need Refrigeration?

Yes — any cake that contains custard, cream, or dairy-based filling should be refrigerated.

✅ Store in an airtight container in the refrigerator for up to 4 days.
✅ Bring to room temperature before serving for the best flavor.
✅ Avoid freezing — it can change the custard texture.

💡 Tip: Refrigeration also enhances the lemon flavor as it chills!

What Makes This Cake Special

• Uses fresh lemon juice for natural brightness.
• The custard layer forms on its own as it bakes — pure kitchen magic.
• Soft, melt-in-your-mouth texture that gets even better after chilling.
• A true Italian nonna recipe: simple, honest, and full of love.
