Preheat oven to 400° F. Grease or line a muffin pan. Set aside.
In a small bowl, combine the flour, sugar, baking powder, and salt.
In a large bowl, beat the egg, vanilla extract, milk, and oil. Add dry ingredients to wet ingredients until combined. Fold in dried blueberries and cranberries.
Bake for 18-20 minutes or until a toothpick comes out clean. Cool for 5 minutes before removing to a wire rack.
