In a large bowl, combine the flour, ¾ cup sugar, cinnamon, baking powder, salt and baking soda. In a small bowl, whisk the egg, buttermilk, butter and vanilla. Stir into dry ingredients just until moistened. Fold in the pear, cranberries and orange peel.
Transfer to a 9-in. springform pan coated with cooking spray and dusted with flour. Combine brown sugar and remaining sugar, sprinkle over batter.
Bake at 350F for 40-45 minutes or until a toothpick inserted near the centre comes out clean. Cool for 10 minutes before removing from pan to a wire rack. Serve warm.
