Start by baking a batch of cornbread according to your favorite recipe. Once cooled, crumble it into small pieces and set aside. This will form the base layer of your salad.

In a bowl, combine the mayonnaise, sour cream, and ranch seasoning mix. Stir until well blended and smooth. This creamy dressing will tie all the layers together.

In a large trifle dish or glass bowl, begin layering the ingredients in the following order: half of the crumbled cornbread, half of the black beans, half of the corn kernels, half of the cherry tomatoes, half of the diced bell pepper, half of the chopped red onion, half of the shredded cheddar cheese, and drizzle half of the ranch dressing over the layers. Repeat the layers with the remaining ingredients, ending with a final drizzle of ranch dressing.

Cover the dish with plastic wrap and refrigerate for at least 2 hours, or overnight if possible. This allows the flavors to meld together. Before serving, garnish with fresh cilantro and a sprinkle of black pepper.
