How to Make the Recipe

Step 1: Prepare the Oven and Pan

Preheat your oven to 325°F (160°C). Line an 8×8-inch square baking pan with parchment paper or lightly grease it.

Step 2: Beat the Egg Yolks and Sugar

In a large bowl, whisk together the egg yolks and sugar until light and creamy.

Step 3: Add Butter, Vanilla, and Lemon

Mix in the melted butter, vanilla extract, lemon juice, and lemon zest until well combined.

Step 4: Incorporate the Flour

Gently fold in the flour until fully blended.

Step 5: Add Milk Gradually

Slowly whisk in the lukewarm milk. The batter will be thin—this is normal.

Step 6: Whip Egg Whites

In a separate bowl, beat the egg whites to stiff peaks.

Step 7: Combine Egg Whites and Batter

Gently fold the whipped egg whites into the batter in three parts. Don’t overmix; it’s okay if some lumps remain.

Step 8: Bake

Pour the batter into the prepared pan and bake for 45–55 minutes, or until the top is lightly golden and the center jiggles slightly when shaken.

Step 9: Cool and Dust

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

Tips for Making the Recipe

Make sure eggs are at room temperature for easier separation and better volume when whipped.
Lukewarm milk helps blend ingredients smoothly without curdling.
Don’t overmix the egg whites into the batter—gentle folding maintains the layers.
Bake on the middle rack to ensure even heat distribution.
Let the cake cool fully to allow layers to set properly before cutting.

How to Serve

Lemon Custard Cake is best served chilled, with a generous dusting of powdered sugar. For an extra touch, add a few fresh berries or a dollop of whipped cream on top. Pair with a light herbal tea or espresso for a balanced finish.

Make Ahead and Storage

Storing Leftovers

Store leftover cake in an airtight container in the refrigerator for up to 3 days. The flavors will continue to develop and improve.

Freezing

To freeze, wrap individual slices in plastic wrap and place them in a freezer-safe container. Freeze for up to 1 month. Thaw overnight in the refrigerator before serving.

Reheating

This cake is typically served cold, but if you prefer a slightly warm slice, heat gently in the microwave for 10–15 seconds.

FAQs

7. Can I double the recipe?

Yes, but use a larger pan and adjust baking time accordingly—watch for the jiggle test!
