1Preheat oven to 400 F. Brush the bottom of a 12-cup nonstick muffin tin with 1 teaspoon of the Olive Oil.
2Combine 1 tablespoon of sugar with 1/2 teaspoon of the cinnamon in a small bowl and set aside. Whisk together the flours, baking powder, salt, and the remaining sugar and cinnamon in a medium bowl and set aside.
3Whisk together the buttermilk, the remaining oil, egg whites, pumpkin, vanilla, and orange zest in another medium bowl. Stir in the pineapple.
4Make a well in the flour mixture, pour in the milk mixture and stir until just blended. Spoon the batter into muffin tins. Sprinkle the sugar and cinnamon mixture evenly over the muffins. Bake 18-20 minutes or until wooden pick inserted in middle comes out clean. Carefully remove from tins and cool completely on a wire rack.
5For added decoration, you can even top with some of the grated orange zest and a tidbit or two.
