In a large mixing bowl, beat 16 oz of softened cream cheese, 2 cups of shredded sharp cheddar, and ½ cup of sour cream together using a hand mixer for 1-2 minutes, until the mixture is smooth and creamy. Add ½ tsp of garlic powder, ½ tsp of smoked paprika, ¼ tsp of onion powder, along with salt and pepper to taste, and mix thoroughly until well combined.

Once your Pumpkin Cheese Ball mixture is smooth, scoop it onto a large piece of plastic wrap. With the wrap, form the mixture into a round ball shape, twisting and securing tightly to maintain the ball's form. Place the wrapped cheese ball in the refrigerator for at least 2 hours, or overnight if you prefer, allowing it to firm up nicely.

After chilling, carefully unwrap the cheese ball and place it on a plate. Roll the cheese ball in 1 cup of crushed crackers or finely chopped pecans. Press lightly to ensure the coating adheres well, giving your Pumpkin Cheese Ball a delightful crunchy exterior that adds to its visual appeal.

To give your cheese ball the charming pumpkin look, use twine or uncooked spaghetti to gently mark vertical ridges on the sides, mimicking the texture of a pumpkin. This adds an inviting dimension to the Pumpkin Cheese Ball. Once done, carefully remove any twine or spaghetti to leave just the markings.

Insert a pretzel rod or a bell pepper stem into the top of your pumpkin-shaped cheese ball to create a whimsical stem that enhances its appearance. For an extra touch, decorate the base with fresh parsley leaves, adding a pop of greenery to your adorable Pumpkin Cheese Ball.

Before serving, allow the Pumpkin Cheese Ball to sit at room temperature for about 15-20 minutes; this helps soften the cheese slightly for easier dipping. Pair it with an assortment of crackers, pretzels, and crisp vegetables, ensuring your guests have a delightful experience with this festive and playful appetizer at your gathering.
