In a bowl, mix warm milk, sugar, and yeast. Let it sit for 10 minutes until foamy.

Add flour, salt, egg, and butter. Knead the dough for about 10 minutes until smooth.

Cover the dough and let it rise for 1-2 hours, or until doubled in size.

Roll out the dough into a large rectangle, about ¼ inch thick.

Cut the dough into triangles using a sharp knife or pizza cutter.

Roll each triangle from the base to the tip to form a crescent shape.

Place the shaped Gipfeli on a baking sheet lined with parchment paper.

Let them rise for another 30 minutes for a fluffier texture.

Preheat the oven to 375°F (190°C).

Brush each Gipfeli with a beaten egg for a golden finish.

Bake for 15-18 minutes until golden brown.

Let them cool slightly before serving.
