Preheat oven to 300 degrees. Grease a 13 x 9 baking pan.
In a large bowl, beat together the butter and sugar. Beat in eggs one at a time. Blend in cream corn, peppers, Monterey Jack and Cheddar cheese.
In a separate bowl, stir together
flour, cornmeal, baking powder and salt. Add flour mixture to corn
mixture; stir until smooth. Pour batter into prepared pan.
Bake in preheated oven for 1 hour, until a toothpick inserted into center of the pan comes out clean.
