Ingredients’ Breakdown for Creamy Cake

For Choux Pastry (Pâte à Choux)

Water: Water works as a binder in the choux pastry. It also helps in hydrating the flour and making the choux pastry crispy and light with a hollow inside..
Butter: We are using fall-fat, unsalted butter for the choux pastry. It adds richness to the choux and helps it cook evenly.
All-purpose flour: Flour is the main ingredient since it gives the pastry body and helps it in holding the shape. Therefore, we are using high-quality all-purpose flour.
Eggs: Eggs will work as a leavening agent. It makes the pastry batter lighter and also adds richness to it.
Sugar: Sugar makes the choux sweet. For this recipe, we are particularly using brown sugar since it gives the choux a deep caramelized flavor. You can use regular white sugar or any type of sweetener of your choice.
Salt: Salt helps in enhancing the flavor of the choux. It really brings out the buttery richness and sweetness.

For Pastry Cream (Crème Pâtissière)

Egg yolks: Egg yolks will help in making the cream super rich. It also gives the cream a silky texture that is literally so blissful.
Sugar: Sugar is the main ingredient in the cream. We are using brown sugar for the authentic caramelized taste. Of course, it will make the cream sweet and indulgent. Again, you can use regular sugar or any sweetener of your choice.
Cornstarch: Cornstarch will work as a thickener for the cream. You can use all-purpose flour as well, but cornstarch makes the cream lighter.
Milk: We are using full-fat milk for a thick and creamy taste and texture. You can use any alternative you like.
Salt: Again, salt brings out the sweetness and helps in balancing the richness as well.
Vanilla extract: Vanilla extract gives the cream floral notes. It is optional, but we highly recommend it.

For Crème Mousseline

Chilled pastry cream: Make sure the pastry cream is super chilled. It will help it fluff up with the butter and sugar, making it lighter as well.
Butter: We are using unsalted butter. Also, make sure that the butter is at room temperature and soft enough to whip.
Sugar: We are using white granulated sugar. You can swap it with any sweetener of your choice.

Ingredients

Choux Pastry (Pâte à Choux)

½ cup Water
½ stick Unsalted butter (At room temperature)
½ cup All-purpose flour
3 Eggs (Large)
2 teaspoons Sugar
A pinch of Salt

Pastry Cream (Crème Pâtissière)

2 Egg yolks
⅓ cup Sugar
3 tablespoons Cornstarch
1⅔ cups Milk
A pinch of Salt
A few drops of Vanilla extract (optional)

Crème Mousseline

Chilled pastry cream (All from above)
1 stick Unsalted Butter
1 ½ tablespoons Sugar

Instructions

For Choux Pastry

1
In a saucepan, combine water, butter, sugar (2 tsp), and a pinch of salt.
Make sure the butter fully melts and the mixture comes to a rolling boil. If the butter isn’t hot enough, the dough won’t come together properly.
2
Remove from heat, add all the flour at once, and stir quickly until combined.
3
Return to medium heat and cook, stirring constantly, for 3–4 minutes to dry the dough.
This step is crucial—drying the dough prevents sogginess and helps the pastry puff up in the oven.
4
Let it cool slightly (5–10 minutes), then beat in eggs one at a time until the batter is glossy and smooth.
5
Divide into two portions, spread evenly on parchment-lined pans (use two 6-inch or similarly sized pans), and bake at 375°F (190°C) for 25–30 minutes until golden. Cool completely on a rack.

For Pastry Cream (Crème Pâtissière)

6
Whisk the egg yolks with half the sugar (from the pastry cream amount) and the cornstarch until smooth.
7
Heat the milk with the remaining sugar, a pinch of salt, and vanilla (if using) to just below boiling.
8
Temper the yolks by slowly pouring the hot milk into the yolk mixture while whisking constantly.
9
Return the combined mixture to the saucepan and cook over medium heat, whisking very actively until it thickens to a custard consistency.
Continuous whisking prevents the eggs from scrambling and keeps the cream smooth.
10
Once thickened, transfer to a bowl, press plastic wrap directly onto the surface to prevent a skin from forming, and chill completely.

For Crème Mousseline

11
Beat the softened unsalted butter with the sugar until pale and fluffy
The butter must be soft but not melted.
12
Bring the chilled pastry cream to a slightly cool, room temperature (so it’s not cold) and add it to the butter very gradually — one spoonful at a time (maximum two spoonfuls at once).
Adding the cream slowly emulsifies it with the butter; adding too much at once can cause separation/curdling.
13
Whip until the mousseline is silky, smooth, and stable.

Assembly

14
Place the first baked choux layer on a serving board.
15
Spread all the crème mousseline evenly over the first layer.
16
Cover with the second choux layer, press gently to even out.
17
Wrap the assembled cake and refrigerate overnight to allow the cream to stabilize and the layers to settle.
18
Dust generously with powdered sugar before serving.

Note

Pro Tips:

Boil the butter/water thoroughly before adding flour.
Cook the choux dough enough to remove excess moisture.
Temper eggs slowly when making pastry cream and whisk constantly.
Add pastry cream to butter very gradually when making mousseline to avoid separation.

Substitutions and Variations

Almond/Oat Milk instead of Milk: It is a great dairy-free option, but it will make the pastry thinner.
Coconut Sugar instead of Sugar: Coconut sugar will lower the GI. The pastry will become darker in color and a slight caramel flavor change.
Gluten-free blend instead of All-purpose flour: It is a great gluten-free option, but it may affect the rise and texture of the choux.

Vegan butter: It is a dairy-free alternative to butter but it can alter the flavor and stability of mousseline.
