You probably have most of the ingredients sitting in your pantry already. This is proof that you don’t need expensive ingredients to make something extraordinary.

So, roll up your sleeves and let’s make a cake that’s soft, buttery, and unforgettable, a dessert that lives up to its name.

Ingredients

For the Dough:

150 g (1 ½ cups) all-purpose flour
100 ml (½ cup) water
100 ml (½ cup) milk
80 g (⅓ cup) butter
4 large eggs
1 teaspoon baking powder
½ teaspoon salt

For the Cream Filling:

500 ml (2 cups) milk
150 g (¾ cup) sugar
100 g (1 cup) all-purpose flour
2 large eggs
180 g (¾ cup) butter

Optional Topping:

Icing sugar, grated chocolate, or fresh berries

Instructions

Step 1: Prepare the Dough

Melt and Combine Liquids:
In a saucepan, melt butter over medium heat. Add milk, water, and salt. Stir until smooth and combined.
Mix the Dry Ingredients:
In a bowl, whisk flour with baking powder.
Cook the Dough:
Slowly add dry ingredients to the saucepan while stirring constantly. Continue mixing until the dough pulls away from the sides and forms a smooth ball.
Cool and Add Eggs:
Transfer dough to a bowl and let it cool slightly (so the eggs don’t scramble). Add eggs one at a time, mixing well after each. The dough should be smooth and slightly sticky.
Bake the Layers:
Preheat oven to 400°F (200°C). Line a 25 cm round pan with parchment paper. Divide the dough into two equal parts. Spread one evenly in the pan and bake for 20 minutes. Repeat with the second half. Let both layers cool completely.

Step 2: Make the Cream Filling

Whisk the Base:
Beat eggs and sugar until pale and frothy. Add flour gradually, then whisk in milk to make a smooth mixture.
Cook the Cream:
Pour into a saucepan and cook on medium heat, stirring constantly, until it thickens. Once it starts to bubble, cook for 3 more minutes. Remove from heat, cover with plastic wrap, and let cool.
Blend with Butter:
In another bowl, beat butter until light and fluffy. Add the cooled cream a spoonful at a time, blending after each addition. You should get a smooth, custard-like cream.

Step 3: Assemble the Cake

Place one baked layer on a serving plate or back into the pan.
Spread half of the cream evenly over it.
Add the second cake layer and spread the rest of the cream on top.
Chill in the refrigerator for at least 2 hours (overnight gives the best texture).

Before serving, dust the top with icing sugar or your favorite garnish.

Tips & Tricks

Prevent lumps: Whisk constantly when cooking the cream — slow and steady wins.
Perfect dough: Don’t overbake — it should be golden and airy, not dry.
Best chilling time: The cream sets beautifully after 2–3 hours in the fridge.
Presentation tip: Sprinkle powdered sugar through a fine sieve for an elegant snowy finish.

Substitutions & Variations

Gluten-Free: Swap flour for a 1:1 gluten-free baking blend.
Dairy-Free: Use plant-based butter and milk.
Flavor Boosts: Add vanilla extract, almond essence, or lemon zest to the cream.
Festive Touch: Layer with jam or top with melted chocolate for a Christmas version.

Frequently Asked Questions

Can I make this cake ahead of time?

Yes! In fact, it tastes even better the next day as the flavors meld together. Store covered in the fridge for up to 3 days.

Can I freeze it?

You can freeze the baked dough layers separately (without cream) for up to a month. Defrost and fill when ready.

Why did my dough deflate?

That’s usually from overmixing or not baking at a high enough temperature. Ensure your oven is fully preheated before baking.
