1 teaspoon vanilla
1 cup coarsely chopped cranberries
1 1/3 cups flour

Make topping: in a small bowl, stir together oats, flour, brown sugar, cinnamon, oil and water until the mixture is crumbly. Set aside.
Make muffins: in a large bowl and using a whisk or electric beaters, combine sugar, milk, oil, egg and vanilla. With a wooden spoon, stir in the cranberries.
In another bowl, stir together flour and baking powder. With a wooden spoon, stir the mixture into the cranberry mixture just until everything is combined. Divide the mixture among the prepared muffin cups. Sprinkle topping evenly over top.
