Prepare the Chai Spice Mix by combining desired amounts of cinnamon, nutmeg, and additional spices. Whisk together until blended and set aside.

Choose your preferred coating sugar, either coarse or powdered sugar, and place it in a shallow bowl for easy access.

Melt the white chocolate and SunButter in a microwave-safe bowl, heating in 20-second intervals until smooth.

Once melted, gently fold in the cereal until coated, then add the chai spice mix and stir until well combined.

Transfer the mixture to a ziplock bag with your chosen coating sugar, seal, and shake to coat the cereal clusters.

Spread the coated mixture on a baking sheet lined with wax paper and refrigerate for at least 4 hours until set.

Break the chilled puppy chow into clusters and store in an airtight container in the fridge.
