In a large bowl, combine 1 Tablespoon dark brown sugar, 1 Tablespoon Cajun seasoning, 2 teaspoons salt, 2 teaspoons garlic powder, 2 teaspoons onion powder, 2 teaspoons chili powder, and ¼ teaspoon cayenne pepper. Set aside.
Using a sharp knife, cut the steak into bite-size pieces, around 1.5-2 inches thick.
Add the cut steak to the bowl of seasoning and toss well to coat. Set aside.
In a large skillet, heat ¼ cup of olive oil over medium high heat. Add the 6 cloves of chopped garlic and sauté for 1 minute.
Working in batches, add the seasoned steak bites and sear for 3 to 4 minutes per side. Remove the steak bites and set aside.Expert Tip: Add more olive oil if the skillet gets dry and smoky between batches. Reduce the heat down to medium and add 1 Tablespoon of butter to the skillet to melt. Slowly whisk in ¼ cup of heavy whipping cream until slightly thick.
Add the steak bites back to the skillet and stir well to coat in the sauce.
Serve immediately over a bed of rice, egg noodles, or on their own.
