**Make the Cheese Mixture:** In a mixing bowl, combine cream cheese, cheddar cheese, jalapeños, bacon bits (if using), garlic powder, onion powder, smoked paprika, salt, and pepper. Mix until well combined.
**Shape into Balls:** Use a cookie scoop or spoon to portion out the mixture into bite-sized balls. Roll each ball between your palms to smooth the edges.
**Prepare the Coating:** On a plate, mix crushed tortilla chips or breadcrumbs with parsley (if using). Roll each cheese ball in the coating until fully covered.
**Chill:** Place the coated cheese balls on a tray and refrigerate for at least 30 minutes to firm up.
**Serve:** Arrange the cheese balls on a platter and serve with crackers, pretzels, or fresh veggies for dipping.
