Preheat your oven to 425 degrees Fahrenheit.
Prepare a baking sheet by spraying it with non-stick cooking spray or lightly coating it with canola oil.
In a large bowl, combine the mayonnaise, eggs, cracker crumbs, mustard, chopped parsley, salt, and pepper.
Mix these ingredients thoroughly.
Gently fold the crab meat into the mixture, ensuring the crab stays chunky and does not break apart too much.
Form this mixture into 3-ounce portions for each crab cake.
Carefully place the formed crab cakes onto your prepared baking sheet.
Leave space between each portion to allow even cooking.
Bake the crab cakes in the preheated oven for about 7 minutes on the middle rack, until golden brown and cooked through.
Keep an eye out to avoid overcooking.
