Sprinkle over the seasoning packet that came with the roast. Sprinkle over the brown sugar. Add the potatoes, carrots, garlic and bay leaf on top of the roast. Pour over the beer.
Add the lid to the slow cooker. The total cooking time is 8 hours on low. You can choose when to add your cabbage. I put my cabbage in at the 6 hour mark and cooked for the remaining 2 hours, that's how I like it. Some like to add it at the beginning, and some at the last 30 minutes.
Serve by removing the veggies and removing the corned beef on to a cutting board. Cut the corned beef into slices and serve with the veggies.
