Ingredients for Lemon Custard Cake

These ingredients create a classic old-fashioned lemon custard cake with a creamy center and light top.

Main Ingredients

• 4 large eggs, separated
• 1 1/4 cups granulated sugar
• 1 tablespoon fresh lemon zest
• 1/2 cup unsalted butter, melted
• 1/2 cup fresh lemon juice
• 1 teaspoon vanilla extract
• 1 cup all-purpose flour
• 1/4 teaspoon salt
• 1 1/4 cups milk, at room temperature
• Powdered sugar for garnish (optional)

Optional Substitutions

• Dairy-free: Use almond or oat milk for the milk, and a dairy-free butter alternative if desired.

How to Make Lemon Custard Cake — Step by Step

Follow these clear steps for a dependable lemon custard cake with a silky interior and light top.

Step 1: Prepare the Pan and Oven

Preheat the oven to 325°F (160°C). Grease a 9×9-inch baking pan and line it with parchment paper for easy removal.

Step 2: Whisk Egg Yolks and Sugar

In a large bowl, whisk the egg yolks with the granulated sugar until the mixture turns pale and creamy, about 2–3 minutes.

Step 3: Add Lemon and Butter

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

Step 4: Combine Dry Ingredients

Sift the flour with the salt, then gradually fold these dry ingredients into the wet mixture until smooth and lump-free.

Step 5: Add Milk

Slowly whisk in the room-temperature milk. The batter should be thin and custard-like.

Step 6: Whip Egg Whites

In a clean, dry bowl, beat the egg whites until stiff peaks form. Gently fold the whipped whites into the batter in two or three additions to maintain airiness.

Step 7: Bake

Pour the batter into the prepared pan and smooth the top. Bake for 40–45 minutes, until the surface is golden and the center still jiggles slightly when nudged.

Step 8: Cool and Serve

Allow the cake to cool completely in the pan so the custard sets. Dust lightly with powdered sugar before slicing. Serve chilled or at room temperature.

Pro Tips for the Best Result

• Use fresh lemons: Fresh zest and juice deliver the brightest flavor and aroma.
• Don’t overmix: Especially when folding in whites—gentle motions preserve volume.
• Cool fully: The custard firms up as it cools; slicing too soon can cause it to be too soft.
• Room-temperature milk and eggs: These ingredients blend more evenly and help proper set.

Common Questions

• Can I make lemon custard cake ahead of time?
  Yes — it often tastes better the next day after chilling and letting flavors meld.
• What makes the cake moist?
  Fresh ingredients, the custard-like batter, and folding in whipped egg whites for lift all contribute to moisture and structure.
• Why isn’t my custard thickening?
  It may be underbaked or the milk was too cold; ensure oven temperature is accurate and milk is at room temperature.

Best Ways to Serve Lemon Custard Cake

Make the most of this dessert by pairing it thoughtfully:

• Top with lightly sweetened whipped cream and fresh berries for color and texture contrast.
• Serve with hot tea or a pitcher of iced lemon water for a coordinated citrus theme.
• Offer it as a light, refreshing finish after seafood or pasta entrees.
