Fluffy Buns with Dulce de Leche

Warm the milk until lukewarm (not hot). Add the yeast and sugar, stir, and let sit for 10–15 minutes until a frothy cap forms.

Add the egg, egg yolk, vanilla sugar, and salt. Mix well.

Gradually add the sifted flour and knead the dough.

Once the dough comes together into a ball, add the softened butter and knead for 10–15 minutes. The dough should become smooth, soft, and slightly sticky.

Transfer the dough to a greased bowl, cover with a towel, and let rise in a warm place for 1–1.5 hours. It should double in volume.

Gently punch down the risen dough and divide into 50–60g portions. Roll each piece into a small flat circle.

Place 1 teaspoon of chilled boiled condensed milk in the center. Pinch the edges tightly and shape into buns.
