Line a large sheet pan with parchment paper and set aside. Measure out the cereal and place in a large bowl; set aside for now.
Add peanut butter, honey, and salt to a large, microwave-safe bowl. Microwave on high for 1 minute. Remove and stir vigorously. Return the bowl to the microwave for another 40 seconds. Remove and stir vigorously again.
Pour in vanilla and mix to combine. Use a spatula to scrape every bit of this peanut butter and honey mixture into the bowl with the cereal. Mix gently until all the cereal is well coated.
Drop clusters about 2 tablespoons in size onto the prepared sheet pan. Gently compress the clusters with your hands to ensure the cereal bites will stay together as they harden. Let stand at room temperature until set, about 1–3 hours. Enjoy!

Notes
Storage: Keep any leftovers in an airtight container in a cool dry place for up to a week. These bites are best when fresh, and each day they lose texture and become overly soft/gooey/chewy (especially in humid climates). This recipe isn’t great for freezing and thawing; the coating softens and the cereal becomes mushy.
