reheat the oven to 350 degrees F.
Once the cornbread is completely cooled, cut in half horizontally and then into 3/4-inch cubes. Spread on a baking sheet and bake for 10 minutes. Turn with a spatula and bake until firm and lightly toasted, about 10 minutes. Remove from the oven, and let cool and harden.
In a medium saucepan, melt the butter over medium heat. Add the onion, corn, salt, and cayenne and cook, stirring, until very soft, 5 minutes. Add the garlic and jalapeno, stir to mix, and cook for 1 minute. Add the cheese and cream and cook gently over low heat, stirring, until the cheese melts and the mixture is smooth. Remove from the heat and pour into a decorative bowl, surrounded by the cornbread cubes. Serve immediately.
