Preheat oven to 400. Add cooking spray to mini or generously coat mini in butter and then add sugar. Shake mini so sugar sticks to all the butter. Make sure everything is coated well so that the rose doesn’t stick.
Using a mandoline or a knife, thinly slice your apples. Transfer to a plate and microwave for about 30 seconds until the apples become pliable but not mushy. Cover in a dish towel to keep warm.
Make your brown butter by adding butter to pan and cook, stirring often until butter starts to caramelize and brown, about 7-8 min.
Make your cinnamon sugar by combining sugar and cinnamon to a small bowl.
Roll out puff pastry dough until it’s about ⅛ inch thick and then cut into strips about 3 inches wide and 12 inches long.
Brush dough with brown butter and then top with cinnamon sugar. Place apple slices along the top of dough along the edge, overlapping the slices slightly. Apples should be sticking out over the edge of the dough. Then fold the bottom of the dough over the slices. Whisk egg and water and brush surface of dough with egg wash.
Roll dough to form a rose and transfer to the mini. Sprinkle with cinnamon sugar. Bake for about 40 min or until dough is cooked. Remove and dust with confectioners’ sugar. Enjoy!
