Step 1

Preheat oven to 350 degrees F. Coat a 9-by-5-inch loaf pan with cooking spray and line with parchment paper, allowing 2 inches to hang over each long side.

Step 2

Whisk flour, sugar, cinnamon, baking soda, salt and baking powder in a large bowl,

Step 3

Whisk oil, applesauce, vanilla and eggs in a small bowl until well combined. Fold the oil mixture into flour mixture until combined. Drain pineapple, reserving juice; set the juice aside. Fold the drained pineapple and shredded zucchini into the batter. Spoon the batter into the prepared pan.

Step 4

Bake until a toothpick inserted in the center comes out clean with some moist crumbs, about 1 hour. (If needed, tent with foil during the last 20 minutes to keep the top from overbrowning.)

Step 5

Brush the top of the bread with the reserved pineapple juice. Transfer to a wire rack to cool in the pan for 30 minutes. Remove the bread from the pan using the parchment as handles. Serve warm or at room temperature.
