Combine butter and garlic in a small bowl. Rub garlic butter evenly over ears of corn. Sprinkle evenly with pepper and salt. Wrap each ear of corn with 2 bacon slices, and secure with wooden picks. Place corn in a 5-quart slow cooker. Add broth and jalapeño pepper.
Cover and cook on LOW 3 to 4 hours or until corn is tender. Remove bacon before serving, if desired.
Bacon Bit: If you don't want to wrap the bacon around the corn, simply chop the bacon and sprinkle on top of the corn in the cooker.
