Preheat the oven to 350 degrees.
In a medium sized bowl, mix together the flour, baking powder, salt, paprika and black pepper.
Sprinkle the cheddar cheese into the dry ingredients, breaking up clumps as you go. Stir a gain.
In a separate bowl, mix together the milk, butter, egg and sour cream. Whisk well.
Slowly pour the liquid ingredients into the dry ingredients. Fold gently until just barely mixed.
Pour the batter into a greased loaf pan and bake for 50 minutes, or until an inserted toothpick comes out clean.
Let cool on a wire rack before eating.
