In a mixing bowl, combine flour, yeast, sugar, and salt.

Add warm milk and melted butter, and mix until a dough forms.

Knead the dough for about 5 minutes until smooth.

Let the dough rise for 30 minutes in a warm place.

Preheat the oven to 375°F (190°C).

Divide the dough into small balls and flatten each one.

Place a spoonful of fruit filling in the center and fold the dough over.

Place on a baking sheet and bake for 20 minutes until golden brown.
