Pour pretzels into a large microwave-safe bowl and pour oil mixture over the top. Stir until coated. Microwave for 1 minute, remove and stir. Microwave 45 seconds more.
Spread warm pretzels evenly on a large cooking sheet.
For Topping:
Mix together the granulated sugar and cinnamon. While the pretzels are still warm, gently sprinkle this evenly all over the tops of pretzels.
Melt white chocolate in microwave, in 30 second increments, until melted. Drizzle over cooled pretzels. Let white chocolate cool and set before serving. Enjoy!
