Cook the Coconut Rice: Rinse rice under cold water. Add to a pot with coconut milk, water, and salt. Bring to a boil, reduce heat to low, cover, and simmer for 15 minutes until tender. Fluff with a fork and set aside.
Make the Mango Salsa: In a bowl, gently mix mango, avocado, red bell pepper, red onion, lime juice, cilantro, and salt. Set aside to let flavors meld.
Season the Shrimp: Pat shrimp dry and toss with olive oil, paprika, smoked paprika, garlic powder, onion powder, cayenne, salt, and black pepper until evenly coated.
Cook the Shrimp: Heat a skillet over medium-high heat. Cook shrimp for 2–3 minutes per side until blackened and just cooked through.
Assemble the Bowl: Spoon coconut rice into bowls, top with blackened shrimp, and finish with a generous scoop of mango salsa. Serve immediately.
