Stir, breaking up the chicken with the spoon.
Spoon cream cheese into the slow cooker. Cover for a few minutes, allowing it to melt.
Remove lid and stir cream cheese into chicken.

Notes
If you can't find jalapeno cream cheese, use plain cream cheese and add a can of diced jalapeno peppers to the slow cooker with the chicken. Stir in the plain cream cheese at the end of the cook time.
