How to Make the Recipe

Step 1: Prep the Oven and Pan

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

Step 2: Separate and Whip the Eggs

Separate the eggs. Beat the egg whites with a pinch of salt until stiff peaks form. Set aside.

Step 3: Make the Batter

In a separate bowl, beat the egg yolks with sugar until light and creamy. Mix in the melted butter and vanilla. Stir in the flour until just combined, then add the lemon juice and zest. Gradually mix in the lukewarm milk until fully incorporated.

Step 4: Fold in Egg Whites

Gently fold the whipped egg whites into the lemon batter, a third at a time. The batter will be thin and a bit lumpy—this is normal.

Step 5: Bake

Pour the batter into the prepared dish. Bake for 45–50 minutes, or until the top is lightly golden and just set. The center should still jiggle slightly when gently shaken.

Step 6: Cool and Dust

Let the cake cool completely in the pan, then refrigerate for at least 2 hours. Dust with powdered sugar before serving.

Tips for Making the Recipe

• Use room temperature eggs for better volume and texture.
• Don’t overmix after adding egg whites; gentle folding preserves the airy structure.
• Warm the milk slightly to prevent curdling when added to the batter.
• Bake in a water bath if you want an ultra-smooth custard layer.
• Chill the cake for clean slicing and best texture.

How to Serve

Serve chilled or at room temperature with a light dusting of powdered sugar. Add a garnish of fresh berries, lemon slices, or a dollop of whipped cream for a beautiful finish. It’s perfect as a light dessert after dinner or as part of a brunch spread.

Make Ahead and Storage

Storing Leftovers

Store the cake in the fridge, covered, for up to 3 days. The texture gets even better as it rests.

Freezing

Freeze individual slices wrapped in plastic and foil for up to 1 month. Thaw in the fridge before serving.

Reheating

Not recommended. This cake is best served chilled or at room temperature.

FAQs

1. Why did my cake not separate into layers?

The egg whites may not have been folded in gently enough, or the batter may have been overmixed. Also, baking temperature matters—too hot and the layers won’t set properly.

2. Can I use bottled lemon juice?

Fresh lemon juice is best for flavor, but bottled will work in a pinch.

3. Can I double the recipe?

Yes, bake in a 9×13-inch dish and increase baking time slightly (check at 55 minutes).

4. How do I know it’s done?

The top should be golden and puffed, and the center should jiggle slightly when shaken.

5. Can I make this cake in advance?

Yes, it actually improves in texture after chilling. Make it a day ahead for best results.

6. Is it supposed to be jiggly?

Yes! The custard layer should be creamy and soft, with a jiggle when you move the pan.

7. What kind of milk should I use?

Whole milk works best for richness and proper texture.

8. Can I skip the lemon zest?

You can, but the zest adds a lot of fresh lemon flavor that balances the sweetness.

9. Can I use a different pan size?

You can, but it will affect the thickness and baking time—stick close to 8×8 for best results.

10. Is this cake gluten-free?

Not as written, but can be made gluten-free with a suitable flour substitute.
