Hard boil your eggs, if you need instructions for that click the link below for perfect hard boiled eggs. While your eggs are cooking, mix together cream cheese, jalapenos, mayo, jalapeno juice, salt, and mustard. Mix until the cream cheese is fully incorporated into the the mixture.
Peel your eggs and add the yolks to the bowl smashing them with a fork as you add them. Mix this until smooth, it will take a few minutes to fully incorporate the yolks. I mix with a large fork using the side of the bowl to smash any yolk that is not broken up yet.
Place the filling in a plastic storage bag and snip off the tip to pipe the filling into the eggs, or use spoon. Whatever method you are more comfortable with. Top with the sliced jalapeno and paprika if desired.
