Blueberry Zucchini Oat Bars are a lightly sweetened oat bar packed with grated zucchini and fresh blueberries. These bars make a wonderful breakfast option or a wholesome snack any time of day.
I recently went blueberry picking with my little one and returned home with more berries than I expected. After a few blueberry-filled breakfasts, I wanted something easy to grab during the week, so I developed these Blueberry Zucchini Oat Bars. They balance gentle sweetness—thanks to maple syrup and mashed bananas—with hearty oats, whole grain flour, and a cup of shredded zucchini for added moisture and nutrients. The blueberries add bursts of brightness in every bite. They’re simple to make, travel well when chilled, and freeze nicely for longer storage.
These bars are intentionally not overly sweet, making them versatile: serve them for breakfast with yogurt, pack them in a lunchbox, or enjoy one as a mid-afternoon snack. Using mashed bananas and maple syrup keeps the added sweeteners minimal while contributing texture and flavor. The shredded zucchini melts into the batter during baking, so the bars stay moist without a heavy vegetable texture—perfect if you want to add a little extra produce into your day without a strong zucchini flavor.
Storage is straightforward: the bars keep best in the refrigerator and will stay good for several days chilled. If you plan to keep them longer, they freeze well—wrap individual bars or the whole pan tightly and thaw as needed. If serving warm, reheat briefly in the oven or microwave; the texture is best when just warmed through.

Ingredients
- 1 cup mashed banana (about 2 large bananas)
- 1/3 cup maple syrup
- 1/4 cup oil (coconut or canola work well)
- 1/2 cup plain whole milk yogurt
- 1 large egg
- 2 cups old fashioned oats
- 1 cup white whole wheat flour
- 1 teaspoon baking soda
- 1/2 teaspoon cinnamon
- 1/2 teaspoon salt
- 1 cup shredded zucchini (about 1 large zucchini)
- 1 cup blueberries
Instructions
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan with cooking spray or line it with parchment paper for easier removal.
- In a large bowl, whisk together the mashed banana, maple syrup, oil, yogurt, and egg until the mixture is smooth and well combined.
- Add the oats, flour, baking soda, cinnamon, and salt. Stir until the dry ingredients are evenly incorporated into the wet mixture.
- Gently fold in the shredded zucchini and blueberries. Be careful not to overmix so the berries keep their shape.
- Pour the batter into the prepared pan and spread it into an even layer with a spatula.
- Bake for 38–40 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean or with only a few moist crumbs.
- Allow the bars to cool in the pan before slicing into squares. Serve at room temperature or chilled.
Tips and Variations
- If fresh blueberries aren’t available, use frozen blueberries but toss them in a tablespoon of flour first to prevent heavy sinking into the batter.
- For a nuttier texture, sprinkle chopped nuts (walnuts or pecans) over the top before baking or stir some into the batter.
- To make these bars dairy-free, substitute a non-dairy yogurt and ensure the chosen oil remains neutral in flavor.
- For extra flavor, add a teaspoon of vanilla extract or a pinch of nutmeg to the batter.
These bars are a practical way to use a surplus of blueberries and zucchini when they’re in season. They strike a balance between wholesome ingredients and a texture that appeals to kids and adults alike. Whether you slice them for a quick breakfast on busy mornings or pack them as a snack, they’re a reliable, tasty option that keeps well and adapts to small substitutions based on what you have on hand.
