In a large mixing bowl, combine 1/2 cup warmed milk, 1 packet (2 1/4 teaspoons) active dry yeast, and 1/4 cup granulated sugar; let sit for about 5 minutes until frothy.

Add 1/2 cup melted unsalted butter, 2 large eggs, and 1 teaspoon vanilla extract to the yeast mixture; stir until fully combined.

In another bowl, whisk together 3 cups all-purpose flour and 1 teaspoon salt; gradually add to the wet ingredients, mixing until a dough forms.

Turn the dough onto a floured surface and knead for about 8 minutes until smooth and elastic.

Place the dough in a lightly greased bowl, cover with a kitchen towel, and let rise in a warm place until doubled in size, about 1 hour.

Punch down the risen dough and roll it out into a large rectangle on a floured surface; use a sharp knife or pizza cutter to cut the dough into a Christmas tree shape.

Sprinkle 1/2 cup chocolate chips or dried fruit over the dough, then fold the branches over the filling to create layers for pulling apart.

Preheat the oven to 350°F (175°C); transfer the shaped dough to a baking sheet lined with parchment paper, brush with a beaten egg, and bake for 25 minutes or until golden brown.

Allow the bread to cool slightly, about 10 minutes, before serving to avoid burns and enhance flavor.
