These bars contain no refined sugar, are gluten-free, and can easily be made dairy-free, making them a wonderful addition to your weekly meal prep rotation.We had a few hours to spare on Thursday before heading to the airport, and I needed to use up some zucchinis since we’d be gone for a bit. So, I decided to make some healthy zucchini oatmeal bars with my son. He’s so excited about cooking, and every time I start dinner, he has to join in, too! I set him up on his standing stool, give him a kid-friendly cutting board, and let him chop up cucumbers, fruits, and potatoes. He especially loves when I bake and insists on putting everything into the mixer himself. At just 2 ½, he can already crack an egg better than I can!We love making healthy blender muffins and blender bars together. He’s a huge fan of the blueberry blender bars, hidden veggie muffins, and the chocolate chip ones! There are so many flavor combos you can make.

Ingredients for Healthy Zucchini Oatmeal Blender Bars + Substitutions

How to Make Zucchini Oatmeal Bars:

Preheat oven to 350 degrees.

Blend zucchini, applesauce, and milk in a blender on medium for about 30 seconds. Blend until the zucchini is speckled into the milk and applesauce mixture but not completely smooth.

Add oats, honey, vanilla, eggs, cinnamon, sea salt, and baking powder to the blender. Mix on medium for another 30 seconds, being careful not to overmix to maintain the oat texture.

Pour the batter into a parchment-lined baking dish (use a 5×9-inch pan) Bake for approximately 30 minutes, adjusting the cooking time based on the size of your baking dish.

Cool, Slice, and Enjoy! Let the bars cool before slicing for the best texture.

Recipe Notes & Tips:

Sweetener Substitutes:

You can replace honey with maple syrup, agave, or date syrup for a different sweetness. Adjust the amount based on your preferred sweetness level.

Add-ins:

Feel free to mix in extras like chocolate chips, nuts, or dried fruit for added texture and flavor. You can also add some flax seeds or chia seeds for an extra boost of nutrients.

Dairy-Free Option:

Use non-dairy milk (such as almond milk, oat milk, or coconut milk) and a dairy-free egg substitute like flax eggs (1 tbsp ground flaxseed + 3 tbsp water, let sit for 5 minutes).

Spice Variations:

Experiment with spices like nutmeg, cloves, or allspice to change up the flavor profile. You can also increase the cinnamon for a more prominent spice flavor.

Texture:

Don’t overmix the batter to maintain the oat texture. If you prefer a smoother texture, you can blend it longer, but be aware it will alter the final texture of the bars.

Muffin Conversion:

To make muffins, simply pour the batter into a muffin tin and bake at 350°F for 18-22 minutes, or until a toothpick comes out clean.

Freezing:

If you have extra bars, freeze them for up to 3 months. Just wrap them individually and store them in a freezer-safe container. Thaw them in the fridge or microwave for a quick snack or breakfast!
