Zucchini Bread
Preheat oven to 325 degrees F. Grease a 9x5 inch loaf pan and sprinkle with granulated sugar on all sides to prevent sticking.
In a medium bowl, whisk together flour, baking powder, baking soda, salt and cinnamon. Set aside.
In a large bowl, whisk together granulated sugar, brown sugar, vegetable oil, egg, vanilla, and zucchini until combined.
Add dry mixture to wet mixture and mix until just combined.
Pour half of the batter into the prepared pan. Sprinkle with cinnamon sugar filling and use a butter knife to swirl it into the batter. Pour remaining batter over the filling. Sprinkle cinnamon streusel topping over the batter.
Bake for 55-60 minutes or until a wooden toothpick inserted in center comes out clean.

Pour the remaining batter over the cinnamon sugar filling and top with cinnamon sugar streusel. Bake at 375 degrees F. for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
