How to Make Lemon Custard Cloud Cake – Soft Layers & Silky Filling Recipe
Step 1: Bake the Sponge
First things first, preheat your oven and prepare your cake pans by greasing and lining them with parchment paper for an easy release. Creaming the butter and sugar together until pale and fluffy is the key to an airy cake crumb. Then, add the eggs one at a time, making sure each is well incorporated before the next. Stir in the vanilla, lemon zest, and fresh lemon juice which infuse the cake with that irresistible citrus aroma. Combining dry ingredients separately and adding them alternately with milk keeps the batter tender and smooth. Baking for about 20 to 25 minutes gives you perfectly golden and springy cake layers that cool beautifully on a wire rack.
Step 2: Make the Lemon Custard
The heart of this Lemon Custard Cloud Cake – Soft Layers & Silky Filling Recipe lies in the lemon custard itself. Whisk together milk, sugar, yolks, cornstarch, lemon zest, juice, and a pinch of salt in a saucepan and cook over medium heat while stirring constantly. This care ensures the custard thickens without lumps and attains a silky smooth consistency. Just as it thickens, remove it from heat and stir in a pat of butter – it’s this final touch that enriches the filling and lends it that luscious texture. Don’t forget to chill the custard completely by pressing plastic wrap directly onto the surface to prevent a skin from forming.
Step 3: Assemble the Cake
Now for the fun part—assembling! Place one sponge layer on your favorite cake stand or plate, then spread the chilled lemon custard evenly on top. This layer of creamy lemon filling is what will elevate your cake to spectacular heights. Gently place the second sponge on top, creating that dreamy sandwich of soft clouds with a silky center.
Step 4: Decorate & Serve
To finish, dust the top of your cake with powdered sugar for a light, pretty presentation. If you’re feeling fancy, add a swirl of whipped cream crowned with a fresh mint leaf right in the center, adding color and extra creaminess. Let the assembled cake chill for 15 to 30 minutes before slicing to ensure clean, neat edges—this makes serving look as delightful as the taste.
How to Serve Lemon Custard Cloud Cake – Soft Layers & Silky Filling Recipe

Garnishes
Simple touches like a dusting of powdered sugar bring out the cake’s elegance while a dollop of whipped cream adds soft sweetness that complements the citrus. Fresh mint leaves not only look beautiful but offer a refreshing aroma and flavor contrast that awakens the palate.
Side Dishes
Pair this cake with a light cup of herbal or green tea, or a glass of sparkling wine to elevate its citrus notes. For a fuller dessert spread, fresh berries like raspberries or blueberries make excellent partners, adding bursts of juicy color and tartness.
Creative Ways to Present
For a stunning centerpiece, serve your Lemon Custard Cloud Cake on a decorative cake stand surrounded by lemon slices and sprigs of mint. Alternatively, cut into slices and plate each with a drizzle of raspberry coulis or a small scoop of vanilla ice cream for an elegant plated dessert that impresses every time.
Make Ahead and Storage
Storing Leftovers
Leftover cake can be stored covered in the refrigerator for 2 to 3 days. Keep it tightly wrapped or in an airtight container to prevent the custard from absorbing other fridge odors and to maintain the sponge’s softness.
Freezing
This cake is best enjoyed fresh, but you can freeze the sponge layers separately by wrapping them well in plastic and foil for up to 2 months. The lemon custard does not freeze well due to its creamy consistency, so prepare that fresh before assembling.
Reheating
If you prefer your cake slightly less chilled, bring slices to room temperature before serving. Avoid microwaving as it may alter the texture of the custard and sponge, diminishing that perfect cloud-like softness.
FAQs
Can I use lemon extract instead of fresh lemon juice and zest?
While lemon extract can add flavor, fresh lemon zest and juice provide much more vibrant and natural citrus brightness that defines this Lemon Custard Cloud Cake – Soft Layers & Silky Filling Recipe, so fresh is definitely best.
Is this cake suitable for beginners?
Absolutely! The steps are straightforward, and the instructions guide you through each essential technique—whether it’s creaming butter and sugar or cooking the custard—to help you achieve a stunning result even on your first try.
Can I substitute the whole milk with another type of milk?
You can use alternatives like almond or oat milk, but whole milk contributes to the tender crumb and custard creaminess that make this cake so special. Using lower-fat or non-dairy milks might slightly change the texture.
How long does the custard take to chill properly?
Chilling the custard for at least 1 to 2 hours (or until completely cold) ensures it sets nicely for easy spreading and keeps the filling unexpectedly smooth and firm within the cake layers.
What’s the best way to get clean, neat slices?
Use a sharp knife dipped in hot water and wiped dry before slicing. This technique helps cut through the soft layers and smooth custard cleanly without tugging or dragging.

Ingredients
Cake Sponge
- 1½ cups all-purpose flour
- 1½ tsp baking powder
- ¼ tsp salt
- ½ cup unsalted butter, room temperature
- ¾ cup granulated sugar
- 3 large eggs
- 1 tsp vanilla extract
- Zest of 1 lemon
- 2 tbsp fresh lemon juice
- ½ cup whole milk
Lemon Custard Filling
- 1 cup milk
- 2 egg yolks
- ⅓ cup granulated sugar
- 2 tbsp cornstarch
- 1 tsp lemon zest
- 2 tbsp lemon juice
- 1 tbsp butter
- Pinch of salt
Decoration
- Powdered sugar, for dusting
- Whipped cream (optional)
- Fresh mint leaves (optional)
Instructions
- Bake the Sponge: Preheat your oven to 350°F (175°C). Grease and line two 8-inch cake pans with parchment paper. In a mixing bowl, cream together the room temperature butter and granulated sugar until the mixture is pale and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract, lemon zest, and lemon juice until combined. In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually alternate adding the dry ingredients and the whole milk to the wet mixture, folding gently until just combined. Divide the batter evenly between the prepared pans and bake for 20 to 25 minutes until the cakes are golden and springy to the touch. Allow the cakes to cool completely on a wire rack.
- Make the Lemon Custard: In a medium-sized saucepan, whisk together the milk, sugar, egg yolks, cornstarch, lemon zest, lemon juice, and a pinch of salt until smooth. Place the saucepan over medium heat and cook, stirring constantly, until the mixture thickens and becomes smooth, which should take about 6 to 8 minutes. Remove from heat and stir in the butter until fully incorporated. Transfer the custard to a bowl and press plastic wrap directly onto the surface to prevent a skin from forming. Refrigerate until the custard is completely chilled.
- Assemble the Cake: Place one of the cooled sponge layers on a cake stand or serving plate. Spread the chilled lemon custard evenly over the top of this layer. Carefully place the second sponge layer on top of the custard layer, pressing lightly to secure.
- Decorate & Serve: Dust the top of the cake with powdered sugar. If desired, decorate with a swirl of whipped cream and garnish with a fresh mint leaf in the center. Chill the cake for 15 to 30 minutes before slicing to ensure clean, neat edges when serving.
Notes
- Ensure the butter is at room temperature for easy creaming with the sugar.
- For a more intense lemon flavor, zest and juice fresh lemons rather than using bottled lemon juice.
- Pressing plastic wrap directly onto the custard prevents an unpleasant skin from forming.
- Chilling the cake before slicing helps achieve clean cuts and a more presentable appearance.
- Optional whipped cream and fresh mint leaves add a lovely complementary flavor and presentation.
