How many calories are in a Halloween Oreo cookie?

Unfortunately, I don't have access to real-time information, including specific product information like calorie counts.

To find out how many calories are in a Halloween Oreo cookie, I recommend checking the following:

* The Oreo package: The nutritional information should be listed on the back or side of the package.

* The Oreo website: You can often find nutritional details for their products on the official Oreo website.

* A nutrition database: Websites like MyFitnessPal or USDA Food Composition Databases provide comprehensive nutritional information for a wide variety of foods.

Remember that calorie counts can vary slightly depending on the specific flavor and size of the cookie.
