Slice the eggs in half lengthwise. Carefully remove the yolks and place them in a bowl. Set the eggs aside on a serving platter.
Mash the yolks with a fork until very fine. Then add mayonnaise, softened butter, mustard, pickle juice, salt, pepper, and Cajun seasoning.
Mix until smooth and creamy. You can use a fork, spoon, or even an electric hand mixer for extra fluffiness.
Spoon or pipe the filling back into the egg whites. (A piping bag with a star tip makes them extra fancy!)
Garnish: Sprinkle with paprika, green onions, bacon and a slice of pickle and enjoy or refrigerate until ready to serve.
