1Preheat the oven to 350F.
2In a small bowl, toss the corn and raspberries with a spoonful of the flour; set aside. In a medium bowl stir together the remaining flour, sugar, cornmeal, baking powder, baking soda, and salt. In a small bowl or measuring cup, whisk together the eggs, buttermilk, and oil. Stir the egg mixture into the flour mixture with a spatula until almost blended; gently stir in the corn and berries, stirring just until combined.
3Spread the batter evenly into a 9-inch cake pan that has been buttered or sprayed with nonstick spray. Bake for 40 to 45 minutes, until golden and springy to the touch.
4 Serve warm, topped perhaps with sweetened sour cream or raspberry ice cream.
