Preheat your oven to 375°F. Line a large, flat baking sheet with parchment paper or spray it lightly with non-stick cooking spray to ensure an easy release.
Heat a large skillet over medium-high heat. Drop in the bulk breakfast sausage and cook for 5 to 6 minutes, using a firm wooden spoon or meat chopper to break it apart into tiny, uniform crumbles. Cook thoroughly until the pork is evenly browned with no pink remaining.
Pour the cooked sausage crumbles into a fine-mesh colander to drain away all excess pooling grease. If desired, blot the meat gently with a paper towel; removing excess surface fat prevents the crescent dough from getting soggy during baking.
Transfer the warm, drained sausage into a medium mixing bowl. Add the softened block of cream cheese, garlic powder, black pepper, and optional shredded cheddar. Stir firmly with a sturdy spoon until the residual heat melts the cheeses, binding the sausage into a smooth, uniform paste.
Pop open the tubes of crescent roll dough and unroll the pre-perforated triangles onto a clean cutting board. For smaller, bite-sized appetizers, use a pizza cutter to slice each triangle in half lengthwise to create two narrow triangles.
Spoon a rounded teaspoon of the savory sausage and cream cheese mixture onto the widest end of each dough triangle.
Roll the dough up loosely toward the pointed tip, tucking the edges slightly around the filling to help trap the cheese matrix inside. Place the assembled rolls seam-side down on the prepared baking sheet, leaving an inch of space between them to allow for steam expansion.
Place the sheet onto the middle oven rack and bake at 375°F for 12 to 15 minutes. Watch the pastries closely; they are finished the exact moment the crescent dough puffs up and takes on a beautiful, golden-brown color.
Remove the pan from the oven and let the bites rest flat on a wire cooling rack for 5 minutes before handling. The internal cheese emulsion will be exceptionally hot right out of the oven; letting it settle prevents the rich filling from spilling out on the first bite. Serve warm.
