Step 1

Preheat the oven to 350 degrees F. Grease two 8 1/2-by-4 1/2-by-2 1/2-inch loaf pans with cooking spray.

Step 2

Combine the flour, baking soda, cinnamon, baking powder, salt, nutmeg and allspice in a small mixing bowl.

Step 3

Beat the sugar, eggs, oil and vanilla in a medium bowl until well combined. Mix in the zucchini and pineapple. Add to the dry ingredients and mix well. Stir in the raisins.

Step 4

Pour half the batter into each loaf pan. Bake, rotating the pans halfway through, until a toothpick inserted in the center comes out clean, about 50 minutes. Let the bread cool in the pans for 5 minutes, then carefully turn out the loaves to finish cooling on a wire rack.
