1. Spray 6-quart oval slow cooker with cooking spray. Cut hot dogs in half lengthwise, then into 1-inch pieces; set aside. Shred enough of the cheese to get 1/2 cup; cover and refrigerate for later. Cut remaining cheese into 1-inch cubes.
2. In 12-inch nonstick skillet, cook beef, onion and garlic over medium-high heat 5 to 7 minutes, stirring occasionally, until beef is no longer pink; drain.
3. Stir in hot dogs, tomato sauce, Worcestershire sauce, 3 teaspoons of the chili powder and the pepper. Heat to simmering; reduce heat to medium, and cook 2 to 3 minutes, stirring frequently, until bubbling and slightly thickened. Remove from heat; transfer mixture to slow cooker. Stir in cheese cubes until well mixed. Cover to keep warm.
4. Separate dough into 8 biscuits. Cut each biscuit into 6 pieces, and transfer to large, resealable food-storage plastic bag. In small bowl, mix melted butter, onion powder and remaining 1 teaspoon chili powder. Pour butter mixture on top of biscuit pieces; seal bag, and shake to evenly coat. Place biscuits in single layer on top of beef mixture in slow cooker.
5. Cover top of insert with large kitchen towel. Place lid on top of towel. (This will prevent condensation from dripping onto biscuits during cooking.) Cook on Low heat setting 2 1/2 to 3 hours or until biscuits are done. Insert knife into center of casserole to test if biscuits are fully baked; outer edge of casserole will be deep golden brown.
6. Sprinkle with reserved shredded Cheddar cheese. Return lid to slow cooker; cook 3 to 5 minutes or until cheese melts. Serve warm.
