Hard boil the eggs using your preferred method. Here is the method I use: How To Make Perfect Hard Boiled Eggs

Peel the eggs and cut them in half lengthwise. Remove yolks and place them in a bowl. Set egg whites aside.

Mash the egg yolks with a fork, then add mayonnaise, softened butter, Dijon mustard, pickle juice, salt, and pepper. Mix until smooth and creamy.

Spoon or pipe the yolk mixture into the egg whites, creating a generous filling in each half.

Garnish each deviled egg with a sprinkle of paprika and a pinch of chopped chives.

Refrigerate for at least 1 hour before serving to allow the flavors to meld and yolk filling to firm.
