Add the Chex, Cheerios, pretzels, peanuts, and oyster crackers in a bowl, and mix well.
In a small saucepan over medium heat, melt the butter. Once melted, add the remaining ingredients and stir until it starts to boil. Once boiling, remove from heat and let cool for a couple of minutes.
Pour the sauce over the mix and using a spatula, toss the mix until fully coasted.
Add the mix to the air fryer and cook at 350°f for 4 minutes. Shake the mixture after 4 minutes and then cook for 3 minutes.
