In a small bowl, stir together egg, mayonnaise, mustard, lemon juice, worcestershire sauce, hot sauce, pepper and creole seasoning.
Add the mayonnaise mixture to the crab and, carefully, fold together being careful not to break up the crab meat too much.
Crumble the remaining sleeve of crackers into a bowl or plate.
Scoop the crab mixture into eight 1/3-cup mounds; lightly pat and form into 8 round patties.
Carefully place the fresh patty into the plate of cracker crumbs and carefully cover each patty with the crumbs.
Place the patties in on parchment paper in a casserole dish or platter.
Cover and refrigerate for 1-4 hours.
In a large skillet, heat butter and oil on medium-high heat. Be careful not to burn the butter.
Add the crab cakes and cook over medium-high heat until patties are deeply golden and heated through, about 3 minutes per side.
Carefully transfer the patties to a wire rack.
Serve hot with a lemon wedge.
