Preheat oven to 400° F. Line a muffin tin with paper muffin cups or spray pan very well with cooking spray. Set aside.
In a medium bowl, combine the flour, cheese, sugar, baking powder, paprika, and salt. Set aside.
In a large bowl, combine the egg and sour cream until smooth. Whisk in the milk and oil.
Add the dry ingredients to the wet ingredients and stir with a wooden spoon until just moistened.
Fill muffin cups 3/4-full.
Bake for 20 minutes or until a toothpick inserted near the center comes out clean. Allow the muffins to cool on a wire rack for 10 minutes before serving.
