Grease a 6 quart crockpot with cooking spray, then pour in olive oil. Set aside.
In a medium sized bowl, whisk together brown sugar, chili powder, ranch mix, paprika, salt, and cayenne. This is our spice rub.
Rub a few spoonfuls of the spice rub onto the steak to fully coat it.
Place steak into the prepared crockpot, then sprinkle on remaining spice rub.
Cover and cook on HIGH for 4 hours or LOW for 8 hours.
Remove steak from the crockpot and use a sharp knife to slice it into strips against the grain (this will basically shred your steak, but will prevent it from creating long and stringy pieces).
Serve as desired - on a bun, in a quesadilla, over mashed potatoes, on top of Mac and cheese, as nachos, etc. with a drizzle of homemade honey mustard sauce, if desired!
