Preheat oven to 200 F = 95 C
Mix the cereal, peanuts, Doritos, pretzels and crackers in a large bowl and set aside.
Melt the butter in a small saucepan over medium heat.
Add sugar and remaining ingredients, stirring with a whisk so the mixture doesn't make clumps.
Slowly pour butter mixture over cereal crackers mixture, tossing gently to coat.
Spread the mixture onto a baking sheet coated with cooking spray.
Bake at for 10 minutes. Check periodically so the mix won't burn.
When almost ready, sprinkle sesame seeds and bake for 2 more minutes.
Cool completely before serving.
