Combine the flours, sugar, baking powder and salt. Whisk together until well combined. Make a well in the middle of the dry ingredients, and add the oil, eggs, sour cream and whisk together til well combined. Add the cream style corn and fold into batter. Scoop into greased or paper lined muffin tins (I like to use an ice cream scoop), and bake at 400 for 15 minutes.
