Yes. As long as your crock pot gets hot enough to bring the dip to a boil, you'll be fine. Just put everything in the slow cooker, stir, turn on high and allow it to boil. I do not know how long it will take for it to come to a boil, and it will depend on the size of your slow cooker too. But the short answer is: yes, you can make this in a slow cooker.
