Place the cream cheese in a microwave-safe bowl and microwave on high for 1 minute.
Stir the cream cheese, add the buttermilk, then microwave 1 more minute; stir until smooth, microwaving an additional 30 seconds if needed.
Whisk in 1/4 cup hot sauce, 1 tablespoon honey, 1 1/2 teaspoons cayenne pepper, and 1 teaspoon garlic powder until fully combined.
Fold the chopped, cooked popcorn chicken into the creamy mixture until evenly distributed.
In a small bowl, combine 2 tablespoons hot sauce, 1 tablespoon honey, and 1/4 teaspoon cayenne; stir to make the drizzle.
Spoon the dip into a serving dish, sprinkle the chopped chicken on top if not already mixed, and drizzle the hot sauce mixture over the chicken.
Garnish with sliced green onion and pickle slices and serve with tortilla chips.
