In a small bowl, mix together the softened butter, honey, smoked paprika, cayenne pepper, garlic powder, salt, and black pepper until smooth. This will be your spicy honey butter.
Carefully cut the corn in half lengthwise to create 'ribs'. You should have a total of 8 pieces from each ear of corn.
Brush each corn rib generously with the spicy honey butter mixture, making sure to coat all sides. Reserve any leftover butter for serving.
Place the corn ribs on the grill or on a baking sheet if using an oven. Grill for about 15-20 minutes, turning halfway through, until they are tender and have nice char marks. If baking, roast for about 25-30 minutes, flipping once.
Once done, remove from the grill/oven and brush them again with a bit more spicy honey butter for extra flavor.
Garnish with freshly chopped cilantro or parsley. Serve with lime wedges on the side for a burst of citrus flavor.
Notes
Adjust the cayenne pepper to taste for desired spiciness.
