Sprinkle cracker crumbs over crab meat.
FOLD all ingredients carefully together. DO NOT OVER MIX. Try and keep the larger pieces intact.

To finish the cakes, beat together the eggs and milk in a shallow dish and then place the flour and panko crumbs in their own shallow dishes. Bread cakes by dipping the top and bottom side of each cake (only) with the following in this sequence: flour, egg mixture and panko crumbs.
Pre-heat oven to 400F then heat a medium size non-stick fry pan on medium high heat and melt butter into the oil. When the oil / butter mix is hot, pan fry cakes on both sides until golden brown and remove to a small cookie sheet.
Place crab cakes in the oven and bake approximately 15 minutes or until the cakes are thoroughly heated through.
