Sift the brown sugar, granulated sugar, salt, chili powder, paprika, black pepper, cumin, garlic powder, onion powder and cayenne pepper into a medium bowl and mix well. Set aside.
Trim all the hard fat from the brisket. Trim all the soft fat to 1/4 inch. Prepare a smoker or a grill, following the manufacturer's directions. Stabilize the temperature at 220 degrees F. Use a mild wood such as hickory or cherry for the smoke flavor. Generously cover all sides of the brisket with the rub and gently massage it in. Reserve the leftover rub. Smoke the meat until an instant-read thermometer registers 170 to 185 degrees F when inserted into the flat part of the brisket, about 1 hour per pound. For example, a 10-pound brisket may need to smoke for about 10 or more hours. Monitor the internal temperature.
Separate the point of the meat from the flat. At this time you can slice the flat part off the brisket and eat. Trim the visible fat from the brisket point and coat it with the reserved rub. Return the meat to the smoker and continue cooking until the internal temperature of the brisket point reaches 200 degrees F. Remove the brisket from the smoker to a cutting board and let it sit for 10 to 20 minutes. Cut into chunks and transfer them to a serving platter. Serve it hot with your favorite sauce on the side.
