This is one of my favorites:

Ingredients
3 tablespoons pancake mix
1 tablespoon prepared DiJon mustard
3 tablespoons mayonnaise
1/4 tsp. Old Bay Seasoning
1 egg, beaten
1 tablespoon chopped fresh parsley
1/4 cup finely chopped red bell pepper
1/4 cup finely chopped onion
1 pound cooked crabmeat, flaked
3 cups vegetable oil for frying

Directions
1. In a medium bowl, stir together the pancake mix, mustard, mayonnaise, egg, onion, bell pepper and parsley until well blended.
Fold in the crabmeat. Form into 3 inch patties.
Place in fridge for 1-3 hours...
2. Heat the oil in a cast iron skillet over medium to medium-high heat.
(There should be enough oil to reach half way up the sides of the crab cakes.)
When the oil is hot, carefully place the patties in the pan.
Fry until golden brown on each side.
Drain on paper towels, and serve immediately.
