In a mixing bowl, beat the softened cream cheese and sour cream with a hand mixer until the mixture becomes smooth and fluffy. Incorporate the garlic powder, chopped jalapeños, shredded cheddar cheese, bacon, salt, and pepper. Stir until all ingredients are evenly combined.
Place two long sheets of plastic wrap on a flat surface in a cross ('X') shape. Spoon the cheese mixture into the center. Gather the edges of the plastic wrap and twist them together tightly to shape the mixture into a ball. Refrigerate for at least 1 hour until firm.
Prepare the coating by spreading the chopped bacon, jalapeño, shredded cheddar, green onions, and pecans evenly on a flat surface. Unwrap the chilled cheese ball and roll it over the coating mixture, pressing gently to ensure the toppings adhere evenly.
Place the coated cheese ball on a serving platter. Pair with low-carb dippers like celery, bell peppers, or pork rinds for a delightful snack.
