01 -  In a large mixing bowl, whisk together all-purpose flour, granulated sugar, instant dry yeast, and salt. Add the warm milk, melted unsalted butter, and egg, and mix until a sticky dough forms. Knead by hand or stand mixer for 6 to 8 minutes, until dough is smooth and elastic. 
 02 -  Transfer dough to a greased mixing bowl, cover, and set in a warm location until doubled in volume, about 1 hour. 
 03 -  In a medium bowl, blend protein powder, almond or peanut butter, softened unsalted butter, coconut or brown sugar, and vanilla extract until smooth. Fold in mini dark chocolate chips. 
 04 -  Punch down the dough and roll out on a floured surface to form a 16x12-inch rectangle. Evenly spread the cookie dough filling over the surface, leaving a 1/2-inch border. 
 05 -  Roll the dough tightly from the long side and seal the seam. Slice into 12 equal rolls. Arrange in a greased 9x13-inch baking dish, cover, and let rise for 30 minutes until rolls puff up. 
 06 -  Preheat oven to 350°F. Bake rolls for 22 to 25 minutes until golden brown. 
 07 -  Whisk powdered sugar, milk, and vanilla extract in a small bowl until smooth. Drizzle the glaze over warm rolls just before serving.
