Prepare Dough: Start by melting 80 grams of butter in a saucepan over low heat. Once melted, mix in 100 ml of milk, 100 ml of water, and ½ teaspoon of salt, stirring until fully combined. Bring the mixture to a gentle boil, then remove from heat.

Mix Dry Ingredients: In a large mixing bowl, whisk together 500 grams of flour and 1 teaspoon of baking powder until well blended.

Combine Mixtures: Gradually add the flour mixture to the boiling liquid, stirring continuously until a smooth batter forms. Allow the batter to cool for about 10 minutes before incorporating 4 eggs, one at a time.

Bake Layers: Preheat your oven to 400°F (200°C). Divide the dough evenly into prepared baking pans, spreading it out to create thin layers. Bake each layer for approximately 20 minutes, or until golden brown.

Make Cream Filling: Beat 4 eggs with 150 grams of sugar until frothy. Slowly mix in the remaining flour and 100 ml of milk. Cook over low heat, stirring constantly, until thickened. Mix in 100 grams of cream.

Assemble Cake: Once cooled, layer the baked dough and cream filling. Refrigerate for at least two hours.

Garnish & Serve: Dust with icing sugar and garnish with fruits or chocolate shavings. Slice and enjoy.
