Step 1

Preheat the oven to 400 degrees F.

Step 2

Whisk the flour, sugar, baking powder, salt and baking soda together in a large bowl.

Step 3

Combine the sour cream, milk, butter, corn and eggs in a blender and blend until smooth. Add to the dry ingredients and whisk until smooth. Butter a 9-by 13-inch baking dish and pour in the batter.

Step 4

Bake until the cornbread springs back when pressed and is golden around the edges, 30 to 35 minutes. Let cool 15 minutes in the baking dish before slicing.
