Make the Dough: In a bread machine (dough setting), stand mixer, or by hand, combine flour, egg, warm milk, yeast, salt, and honey or sugar. Mix until a soft, supple dough forms. It should be smooth, not lumpy.
First Proof: Cover and let the dough rise for about 1 hour or until doubled in size. Punch it down to release the air.
Roll Out: On a lightly floured surface, roll the dough into a large 16x9-inch rectangle.
Preheat Oven: Set your oven to 350°F. Line a 9x13 baking dish with parchment paper.
Assemble Filling: Spread the soft butter evenly over the dough. Then layer the strawberry jam, followed by the cinnamon, and finally sprinkle the diced strawberries evenly over the surface.
Shape & Slice: Roll the dough tightly away from you, ending seam side down. Slice the log into 9 even rolls.
Caramel Base: Sprinkle brown sugar over the base of your parchment-lined baking dish. Pour melted butter evenly over the top.
Second Proof: Arrange the rolls in 3 rows of 3 in the pan. Let them rise again for 20–30 minutes until slightly puffy.
Bake: Bake for about 30 minutes, or until the rolls are golden and the centers are cooked through.
Make the Frosting: While the rolls bake, beat together cream cheese, butter, freeze-dried strawberries, and powdered sugar until smooth. Add heavy cream, a little at a time, until desired consistency is reached. Add a pinch of salt to balance the sweetness.
Serve: Spread the strawberry buttercream generously over the warm rolls. Enjoy immediately with cold milk or a celebratory glass of champagne!
