Preheat the oven to 350 degrees. Once the oven is warm, place the corn directly on the oven rack and bake for 35 minutes. While the corn is roasting, prepare the honey chili butter. In a small bowl, combine the butter, chili powder, and honey. Either mash together with a fork or whip with a mixer. This is easiest if the butter is room temperature or close to it. Once the corn is done roasting, carefully remove it from the oven with an oven mitt, clean kitchen towel, or tongs. Carefully peel back the husks and remove the corn silk. Slather the kernels with honey chili butter. The husks can serve as a handle while eating.
