Preheat oven to 250 F.

Spray a large bowl, a large sauce pan, and a deep roasting pan with non-stick spray. You may also want to spray your utensils as you go since these are quite sticky!

Add the brown sugar, butter and corn syrup to the sauce pan over medium high heat. Bring to a boil and let boil for 5 minutes, stirring constantly.

Remove the saucepan from the heat and stir in the baking soda. The mixture will become light in color and will be somewhat foamy.

Pour the Cheetos into the large bowl. Pour the caramel mixture over the top. Stir the Cheetos to coat. You don't have to worry about getting every one fully coated as they will get tossed more in the oven.

Pour Cheetos mixture into the roasting pan and place into the oven.

Bake at 250 for 1 hour, stirring every 15 minutes.

Remove from oven and pour onto wax paper. Allow to cool.
