Preheat oven to 350 degrees.
To prepare the baking sheet, place a cooling rack on a 13 by 18" baking sheet.
In a food processor, pulse the Flamin Hot Cheetos until the Cheetos are the size of rice grains. Pour into a plate with edges or a 9"pie plate.
In a mixing bowl, combine the buttermilk, ranch dressing, egg, flour, garlic powder, onion powder, salt, and pepper. Mix until combined.
Add the chicken tenders to the batter and toss with tongs until the chicken tenders are covered in the batter.
With tongs, pull one chicken tender out at a time and roll in the ground Cheetos. Place the chicken on the baking sheet and repeat this step until all the chicken tenders are covered in ground Cheetos.
Bake in a preheated 350-degree oven for 35-40 minutes or until the internal temperature of the chicken reads 165 degrees Fahrenheit.
These chicken tenders can be served with ranch or blue cheese dressing. Enjoy!
