Add the Chex cereal, chocolate-covered pretzels, candy corn, chocolate candies, and Halloween-shaped candies to a large bowl.
Gently toss everything together until evenly combined.
Spread the snack mix onto a parchment-lined baking sheet and sprinkle with Halloween sprinkles.
Let the snack mix sit for 15–20 minutes before transferring it to a serving bowl.
Recipe Notes
Customize the mix with your favorite Halloween candies and snacks. Popcorn, mini marshmallows, or different varieties of chocolate-covered pretzels would all be fun additions.
Store leftovers in an airtight container at room temperature.
