For the chili sauce: Brown the ground beef, onions and garlic. Drain the grease. Add the paprika, cinnamon, chili powder and cumin. Stir well and cook about 1 minute. Add in the ketchup, tomato paste, brown sugar and water. Mix well. Cook 3-4 hours on low heat, stirring occasionally. Add more water if needed. Once the chili sauce is done, use a stick blender to make the consistency you want.
To assemble the chili cheese dogs: Preheat the oven to 350°.
Spread a small amount of mayo in each bun. Place the hotdog inside the bun and set each one in a casserole dish.
Spread the top of each hotdog with nacho cheese.
Spoon the chili sauce on top of the nacho cheese.
Sprinkle shredded cheddar cheese on top of each hotdog.
Cover the pan with aluminum foil and bake for 45 minutes. Serve and savor each bite!
