This pineapple zucchini bread is my favorite way to use up late-summer zucchini and enjoy a moist breakfast treat with a splash of tropical flavor. With the sweetness of pineapple and a soft crumb, it is hard to eat just one slice.
I baked this for a garden club meeting one summer and watched everyone ask for seconds. Now it is the dessert I always bring to potlucks.

- Combine the Wet Ingredients:

Zucchini is my favorite part because it boosts moisture without making the bread taste like vegetables. My kids never know it is there and always ask for another slice. The first time I made this my husband guessed the pineapple but could not figure out the secret ingredient.
Storage Tips
Keep the cooled bread covered at room temperature for up to three days or refrigerate for a week. Wrap the loaves tightly in plastic wrap before freezing for up to three months. For best flavor and texture bring frozen bread to room temperature before serving.
Ingredient Substitutions
No buttermilk in the fridge Combine one cup of milk with a tablespoon of lemon juice or vinegar and let sit for five minutes. You can use applesauce in place of oil if you want to cut fat. Try dried coconut or chopped pecans for extra flavor.
