Knead the egg yolks, flour, and milk with the hook attachment of a stand mixer until no liquid remains visible. Add the softened butter and continue kneading until the dough comes together completely.

Cover with parchment paper and refrigerate for 2 hours to allow gluten to relax.
04 -
Preheat the oven to 200°C.
05 -
Divide the chilled dough into 12 equal pieces.
06 -
Roll each piece into rounds of 20-22 cm in diameter using a rolling pin. Keep unused portions covered to prevent drying.
07 -
Prick each round with a fork to prevent air bubbles while baking.
08 -
Bake each round for 7 minutes until lightly golden. Handle with care as they cool on a wire rack, as they are very fragile.
09 -
Separate egg whites from yolks and leave the whites covered at room temperature overnight to stabilize.

In a stand mixer bowl, warm the egg whites and powdered sugar over a water bath until the sugar completely dissolves, whisking gently throughout. If using a thermometer, heat to 55-60°C.

Place one disc of crust on a serving plate and spread 2 generous tablespoons of dulce de leche evenly across the entire surface.
13 -
Gently place another disc on top. Minor cracks are acceptable as they will be covered by the dulce de leche.
14 -
Continue alternating dulce de leche and pastry discs until all layers are used, ensuring the final layer is pastry.
15 -
Refrigerate the layered cake overnight to allow flavors to meld and structure to stabilize.

Cover the entire cake with the prepared swiss meringue, creating decorative peaks if desired.
