Combine flour, sugar, and salt in a large bowl. Sprinkle the instant yeast over the mixture and mix it in gently.

Create a well in the center of the dry ingredients and add warm milk and eggs into the well. Beat them together gently with a fork.

Stir in the rest of the flour mixture until a sticky dough forms.

Knead the dough until smooth (about 10 minutes) and passes the windowpane test.

Form into a ball, cover with plastic wrap, and let rise until doubled in size (about 1 hour).

Punch down the dough, divide into 16 equal pieces, and shape each into a 4x4 inch square.

Place a cheese stick at one end, roll it up while tucking in the sides, and seal.

Arrange on a parchment-lined baking sheet, cover, and let rise until doubled (about 30 minutes).

Preheat oven to 160 degrees C and bake for 12-15 minutes, or until golden brown.

Cool slightly, then brush with softened butter and sprinkle with sugar.
