What Kind of Lemons Should I Use?

The best lemons for this recipe are fresh, unwaxed lemons with vibrant yellow skin and a strong, aromatic scent. Meyer lemons, if you can find them, add a slightly floral, sweet note, but classic Eureka or Lisbon lemons are perfect as well. Freshly squeezed lemon juice is essential for the best flavor—bottled juice just doesn’t compare when you want that bright, tangy lift!

Ingredients for the Italian Grandma’s Lemon Custard Cake

Each ingredient plays an important role in this delightful cake, so let’s take a look at why you need them:

• Eggs: These create the structure and help the cake separate into two beautiful layers—sponge and custard.
• Sugar: Balances the tartness of the lemon and gives the cake its sweetness.
• Unsalted Butter: Adds richness and a tender crumb, bringing everything together.
• All-Purpose Flour: Forms the backbone of the cake, supporting both the custard and the cake layers.
• Fresh Lemons (juice and zest): The star ingredient, giving the cake its zesty, fresh, and slightly tangy flavor.
• Whole Milk: Essential for that creamy custard texture.
• Powdered Sugar: For dusting on top, adding a sweet and elegant finish.
• A pinch of salt: Enhances the flavors and balances sweetness.

Every ingredient is chosen for how it contributes to the cake’s unique taste and texture—no substitutions for the real thing!

How To Make Italian Grandma’s Lemon Custard Cake

Follow these steps to achieve the perfect lemon custard cake every time:

Step 1: Prep Your Ingredients

Zest and juice your lemons, melt your butter, and separate your eggs. Having everything ready makes assembly quick and smooth.

Step 2: Whip Egg Whites

Beat the egg whites until stiff peaks form. This will help the cake develop its classic airy top layer.

Step 3: Mix Yolks, Sugar, and Lemon

In another bowl, beat the egg yolks with sugar until pale. Stir in the lemon zest, juice, and melted butter for bright flavor.

Step 4: Add Dry Ingredients

Gently fold in the flour and a pinch of salt, being careful not to deflate your mixture.

Step 5: Add Milk

Slowly mix in the milk—your batter will be quite runny at this stage (that’s what creates the custard layer!).

Step 6: Fold in Egg Whites

Carefully fold in the beaten egg whites. The batter will look a bit uneven—this is normal.

Step 7: Bake

Pour the batter into a lined or greased pan and bake until the top is golden and set. The center should have a gentle wobble.

Step 8: Cool and Dust

Allow the cake to cool completely, then dust generously with powdered sugar before slicing and serving.
