Make the Dough:
In a large mixing bowl, combine the warm milk and sugar. Sprinkle the yeast over the top and let it sit for 5-10 minutes until foamy.
Add the melted butter, vanilla extract, salt, and egg to the yeast mixture. Mix until combined. Gradually add in the flour and knead the dough on a floured surface for about 5-7 minutes until it’s smooth and elastic.
Let the Dough Rise:
Place the dough in a greased bowl, cover it with a clean towel, and let it rise in a warm place for 1 to 1 ½ hours, or until it doubles in size.
Prepare the Filling:
While the dough is rising, mix the brown sugar and cinnamon in a small bowl. Set aside.
Chop the fresh strawberries into small pieces, keeping them aside for later.
Roll Out the Dough:
Once the dough has risen, punch it down and roll it out on a floured surface into a rectangle (about 12x8 inches).
Spread the softened butter over the dough, then evenly sprinkle the cinnamon-sugar mixture over the butter.
Add the Strawberries:
Evenly distribute the chopped strawberries over the cinnamon-sugar layer.
Form the Rolls:
Starting from one of the long edges, tightly roll the dough into a log. Cut the log into 8-10 even slices using a sharp knife or dental floss.
Bake the Rolls:
Place the rolls in a greased baking pan or on a baking sheet. Cover with a towel and let them rise for an additional 30 minutes.
Preheat the oven to 350°F (175°C). Bake the rolls for 20-25 minutes or until golden brown on top.
Make the Strawberry Glaze:
While the rolls are baking, whisk together the powdered sugar, strawberry puree, vanilla extract, and milk in a small bowl until smooth. Adjust the milk to get the desired glaze consistency.
Glaze the Rolls:
Once the rolls are out of the oven, let them cool for a few minutes before drizzling the strawberry glaze over the top.
Serve:
Serve the rolls warm with extra glaze on the side, if desired. Enjoy with a cup of coffee or tea!
