Instructions
Dough
Lightly grease a 9x9 square baking dish or 9-10 inch round cake or pie pan and set aside.
In a large bowl, add flour, granulated sugar, and salt. Whisk to combine. Set aside.
In a microwave safe bowl, add milk and butter. Microwave in 20 second increments until butter has melted and mixture is warm to the touch, but not hot (about 110 degrees Fahrenheit).
Whisk in yeast and continue whisking until yeast has dissolved. Pour yeast mixture into dry ingredients. Add the egg and stir with a sturdy wooden spoon until a soft dough forms.
Turn dough out onto a lightly floured surface. Using floured hands, knead the dough for 3 to 5 minutes, or until dough looks smooth (not sticky).
Transfer dough to a lightly greased bowl, lightly cover, and allow to rise for 10 minutes.
Filling and streusel
In a bowl, add filling ingredients: blueberries, sugar, and cornstarch. Toss until coated. Set aside.
Roll dough out on a lightly floured surface into a 14x9 rectangle. Pour blueberry filling over dough.
Starting at the long 14 inch side, roll dough up into a log. Using a serrated knife, slice into 9 even rolls and place into prepared baking dish.
Lightly cover and allow rolls to rise at room temperature for 60-90 minutes, or until they've doubled in size.
Preheat oven to 350℉.
In a bowl, add streusel ingredients: flour, brown sugar, melted butter, cinnamon, and salt. Stir until clumps form - mixture will look thick and crumbly. After rolls have risen, top with streusel.
Transfer dish to the oven and bake, uncovered, for 25-30 minutes, or until golden brown across the top and rolls reach 195-200 degrees Fahrenheit in the center (use an instant read thermometer to test internal temperature). If rolls are browning too quickly, lightly tent with foil for the remaining baking time.
While the rolls bake, preparing the icing.
Icing
In a medium bowl, add confectioner's sugar, whole milk, and vanilla extract. Stir until smooth. Add more milk as needed to reach desired consistency.
Drizzle icing over warm cinnamon rolls and serve immediately.
Notes
Overnight directions: After assembling the blueberry rolls, cover and transfer to the refrigerator to rise overnight (this replaces the 60-90 minute rise). In the morning, remove cinnamon rolls from the refrigerator and uncover while the oven preheats. Add streusel topping, then bake as directed in the recipe card above.
Leftovers: Store leftover cinnamon rolls covered in the refrigerator for 4-5 days, or at room temperature for 2-3 days.
Freezing baked rolls: Baked cinnamon rolls freeze well and keep for up to 3 months.
Freezing unbaked cinnamon rolls: Follow the directions above for assembly and rising, using a disposable foil pan (or other freezer-safe pan you don't mind freezing for a while). Bake your cinnamon rolls at 350F for 10 minutes. They should look risen and par-cooked, but not yet browned. Cool completely, then cover tightly and freeze for up to 3 months. Transfer to the refrigerator to thaw overnight. In the morning, preheat your oven to 350F and bake for the remaining 15-18 minutes.
