- Banana Zucchini Oatmeal Bars (no added sugar, high fiber)
Ingredients You'll Need
Here's what you need to make these banana zucchini oatmeal bars:
- bananas – naturally sweeten the bars without added sugar and help bind everything together for a soft, toddler-friendly texture
- rolled oats – provide slow-digesting carbohydrates and fiber to keep little tummies full and support steady energy
- zucchini – adds moisture and nutrients while blending right into the bars when grated finely
- egg – helps bind the bars and adds protein and healthy fats to support growth and fullness
- milk of choice – adds moisture and contributes calcium and vitamin D for growing bones (use dairy-free if needed)
- coconut oil or olive oil – provides healthy fats that support brain development and help create a soft, tender crumb
- vanilla extract – enhances natural sweetness and flavor without needing added sugar
- cinnamon – adds warmth and flavor while gently introducing spices in a toddler-friendly way
- baking powder – gives the bars a light lift so they’re soft and easy to chew, not dense or gummy

How To Make Your Zucchini Oatmeal Bars
- Step 1: Preheat oven to 350°F and line an 8×8 pan with parchment paper. In a bowl, mash bananas until smooth, then stir in egg, milk, oil/butter, and vanilla.
- Step 2: Fold in oats, zucchini, cinnamon, and baking powder until just combined.
- Step 3: Pour batter into pan, smooth the top. If adding, sprinkle mini chocolate chips, hemp hearts, or blueberries on top!
- Step 4: Bake for 25-30 minutes until set in the center. Cool completely before slicing.
Hint For The Best Zucchini Oatmeal Bars
Make sure to squeeze as much moisture as possible from the shredded zucchini before adding it to the batter. Too much liquid can make the bars soft in the middle or difficult to slice. Grating the zucchini very finely also helps it blend in seamlessly for texture-sensitive toddlers (not "hiding" we're adding).
Substitutions
These banana zucchini oatmeal bars are already gluten-free if using gluten-free rolled oats, but here are some other substitutions if needed!
- egg-free: replace the egg with 1 flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water), let sit for 5 minutes before adding to the batter
- dairy-free: use any unsweetened dairy-free milk such as almond, oat, or coconut milk
- gluten-free: use certified gluten-free rolled oats to keep the bars fully gluten-free
- banana: can swap with ½ cup unsweetened applesauce or pumpkin puree
Variations
You can totally add different mix-ins to these zucchini oatmeal bars if you want!
- chocolate chip zucchini oatmeal bars - add a handful of mini chocolate chips
- blueberry zucchini bars - add a handful of frozen or fresh blueberries
- almond cherry zucchini bars - add a small handful of frozen cherries + ⅓ cup of slivered almonds
Equipment
You’ll need a mixing bowl, fork or potato masher for the bananas, a box grater for the zucchini, measuring cups and spoons, an 8×8 baking pan, and parchment paper for easy removal and slicing. No mixer required, which makes this an easy one-bowl toddler snack recipe.
Storing Your Banana Zucchini Oatmeal Bars
Store leftover banana zucchini oatmeal bars in an airtight container in the refrigerator for up to 5 days. For longer storage, slice the bars and freeze in a single layer, then transfer to a freezer-safe bag or container for up to 2 months. Thaw overnight in the fridge or at room temperature before serving.
Tiff's Dietitian Tip
Toddlers can be unpredictable, and what I love about these bars is that they can truly be transformed into different meals! Serve in a bar form, cut into a shape, form into a cookie, or even crumble over a yogurt parfait.
FAQ
These oatmeal bars are great for 6 months and up, depending on your little one's chewing skills. They can be mashed/crumbled for babies (served more like oatmeal style), cut into bite-size pieces for young toddlers, or served as a whole bar for easy grabbing.
Yes. Removing excess moisture helps the bars bake evenly and makes them easier to slice instead of gummy in the center.
Absolutely. Use any unsweetened dairy-free milk that works for your family!
