Preheat the oven to 400 degrees F. Line a baking sheet with foil and spray or brush it with the olive oil.
Crumble the corn bread into fine crumbs over the baking sheet. Drizzle the melted butter over the crumbs. Toast in the oven for about 10-15 minutes, stirring once or twice until golden and crisp. Remove from the oven and increase the temperature to 475 degrees F.
In a bowl combine the buttermilk and the chicken, toss well.
Add half the toasted cornbread crumbs to a shallow bowl and stir in the cheddar cheese cracker crumbs. Remove each piece of chicken from the buttermilk, and dredge through the cornbread crumbs, pressing gently to adhere. Place on the prepared baking sheet. Repeat until all the chicken has been used. Make sure not to crowd your pan, if necessary use two baking sheets. Lightly spray the fingers with cooking spray or a mist of olive oil.
Bake for 10-12 minutes, then gently flip using kitchen tongs and spray the other side. Bake for 10-12 minutes more, then remove from oven and serve with the Jalapeño Honey Butter (recipe below).
