Feel free to add more jerk seasoning to the black beans if you prefer your dishes spicier, or try the recipe with 1 Tbs. chili powder instead. For rich, smoky flavor, choose fire-roasted diced tomatoes with green chiles.
Preheat oven to 350°F. Lightly oil 8-inch-square baking dish with olive oil.
Stir together beans, tomatoes and juices, corn, jerk seasoning, 1/4 tsp. salt, and pepper in medium bowl. Adjust seasonings with more jerk seasoning, if desired. Spread in prepared baking dish.
Whisk together flour, cornmeal, sugar, baking powder, and remaining 1/4 tsp. salt in separate bowl. Add coconut milk and 2 Tbs. oil, and stir until just combined—do not overmix. Spread batter over bean mixture with spatula. Bake, uncovered, 30 minutes, or until topping is lightly browned and toothpick inserted in center of topping comes out clean. Let stand 5 minutes before serving
