Roll thawed dough onto a lightly floured cutting board or floured piece of parchment paper to form a 12x18 rectangle.
In a small bowl, mix together the softened butter, brown sugar, cocoa powder, and cinnamon to form a paste.
Use a spatula to spread the butter/sugar mixture over the dough.
Roll the dough up tightly into a log.
Slice the log into 12 - 2-inch wide pieces.
Place the cinnamon rolls in a lightly greased 9x13 baking dish, leaving equal space between all of the rolls. Cover with a light towel and place in a warm, draft-free location. Leave to rise for 1 - 1 ½ hours, until puffy.
Preheat oven to 350°F.
Pour the heavy cream over the cinnamon rolls.
Bake for 20-25 minutes, until the cinnamon rolls are lightly browned and cooked through.
Beat or stir together optional frosting ingredients. Spread frosting over warm cinnamon rolls and top with remaining cup of crushed Oreo cookies.
Notes
Notes:Use a bench scraper to cleanly cut through the roll dough. The dough will be soft though easier to slice and transfer than when using a crescent dough, for example.Frozen bread dough makes a nice base for cinnamon rolls. It’s easy to use and has a nice neutral flavor. Thaw a frozen loaf in the refrigerator until thawed through. You don’t want to set it out on the counter because once it thaws and warms it will begin to rise. It’s important to form, roll, and slice the cinnamon rolls and THEN let them rise.You can also use your favorite homemade sweet roll dough as your base. Using pre-made bread dough comes in handy for quicker results.The heavy cream over the top of the cinnamon rolls adds moisture and makes a gooey base in the bottom of the pan.
