Preheat your oven to 350°F (175°C) to ensure even roasting.

Rinse the pumpkin seeds in a colander to remove debris and pat them dry.

In a large mixing bowl, combine the pumpkin seeds with olive oil, buffalo wing sauce, ranch seasoning mix, and garlic powder.

Spread the seasoned seeds in a single layer on a non-stick baking sheet.

Roast the seeds for 25 to 45 minutes, stirring every 15 minutes.

Check for crispness; if soft, continue roasting in 5-minute increments.

Once golden and crisp, let the seeds cool completely on the baking sheet.
