Prepare the Dough
In a small bowl, dissolve the yeast in warm milk with 1 tablespoon of sugar. Let it sit for 5-10 minutes until the mixture is frothy.
In a large mixing bowl, combine the melted butter, remaining sugar, vanilla extract, salt, and egg. Add the yeast mixture and stir to combine.
Gradually add the flour, 1 cup at a time, until a soft dough forms. Knead the dough for about 5-7 minutes, either by hand or using a stand mixer with a dough hook, until it’s smooth and elastic.
Let the Dough Rise
Place the dough in a lightly greased bowl, cover with a clean towel, and let it rise in a warm place for 1 to 1.5 hours, or until it has doubled in size.
Make the Strawberry Filling
While the dough is rising, chop the fresh strawberries into small pieces. In a small bowl, combine the chopped strawberries, brown sugar, cinnamon, and melted butter. Stir until the strawberries are well coated and the mixture is combined.
Roll Out the Dough
Once the dough has risen, punch it down and transfer it to a floured surface. Roll the dough into a large rectangle (about 12x18 inches).
Assemble the Rolls
Spread the strawberry mixture evenly over the rolled-out dough. Starting from the longer edge, tightly roll the dough into a log.
Cut the rolled dough into 12 equal slices using a sharp knife or pizza cutter.
Bake the Rolls
Place the rolls into a greased 9x13-inch baking pan, spacing them closely together. Cover with a clean towel and let the rolls rise for another 30-45 minutes, or until they’ve puffed up.
Preheat your oven to 350°F (175°C).
Bake the rolls for 20-25 minutes, or until they’re golden brown and fully cooked through.
Make the Glaze
While the rolls are baking, make the glaze by whisking together the powdered sugar, milk, vanilla extract, and salt in a small bowl until smooth.
Glaze and Serve
Once the rolls are done baking, remove them from the oven and let them cool for about 5 minutes.
Drizzle the glaze over the warm rolls and serve immediately.
