Add the avocado, mayonnaise, cilantro, lime juice, and water to a blender or food processor. Blend until completely smooth. Add more water, 1 tablespoon at a time, if needed to reach your desired consistency. Season with salt to taste and set aside.
Pat the shrimp dry with a paper towel, then season with the blackened seasoning.
Heat a large skillet over medium-high heat. Add the shrimp and cook for 1-2 minutes on each side or until almost fully cooked. Add the honey and toss to coat. Cook for an additional 30-60 seconds, or until the shrimp are fully cooked and lightly caramelized. Remove from the heat.
Char the corn in a hot skillet or on a grill, turning occasionally, until lightly charred on all sides. Allow it to cool slightly, then carefully slice the kernels off the cob. Alternatively, use canned corn. Drain it well, warm it in a skillet, and season with salt and pepper.
Toss the cherry tomatoes with the olive oil and season with salt and pepper. Season the sliced avocado with salt and pepper.
Divide the cooked rice evenly among 4 bowls. Top each bowl with the blackened honey shrimp, charred corn, cherry tomatoes, and sliced avocado.
Drizzle generously with the avocado sauce and serve immediately.
