In a bowl, mix together flour, yeast, sugar, and salt.

In another bowl, combine warm milk, melted butter, and egg. Add to the dry ingredients and mix until a dough forms.

Knead the dough on a floured surface until smooth, then let it rise until doubled in size.

Roll out the dough into a rectangle and spread softened butter over it.

Sprinkle brown sugar and cinnamon evenly over the butter.

Evenly distribute the sliced strawberries on top.

Roll the dough tightly into a log and cut into rolls.

Place the rolls in a greased baking dish and let them rise again.

Bake in a preheated oven at 375°F (190°C) for 25 minutes or until golden brown.

For the glaze, mix powdered sugar, milk, and vanilla until smooth. Drizzle over warm rolls.
