Place the chicken tenders in a large glass bowl with the buttermilk and kosher salt, allow to sit in the fridge for at least 20 minutes, up to overnight.
Pulse 12 cups of cornflake cereal in a food processor until you have about 4 cups of crumbs. Place in a shallow dish and mix in the flour, thyme, and salt.
When ready to make, preheat the oven to 425 degrees. Line two baking sheets with parchment paper
Remove the chicken tenders from the buttermilk, and dredge in the cornflake crumb mixture. Place them with space between, on the baking sheets. Drizzle the tenders with olive oil, and bake for 15 minutes. Flip the tenders, continue to bake for another 10 minutes until thoroughly cooked (165 degrees).
While the chicken is baking, heat the butter in a small saucepan, and stir in the other ingredients for the hot honey (butter through paprika). When the chicken is done, spoon the hot honey sauce over the tenders while hot - sprinkle with extra kosher or flaky salt. Allow to set for a few minutes.
