    My Flourless Chocolate Chip Zucchini Loaf is the best healthy dessert that's lower sugar and full of veggies. Dairy-free and gluten-free!

    We're currently harvesting our summer garden which means the zucchinis are in abundance. I love using zucchinis in savoury recipes like my cheesy white bean tomato bake and beef zucchini casserole, but it's also amazing in sweet recipes like this loaf.

    This chocolate chip zucchini loaf is moist, chocolatey, and just sweet enough while still being fairly low in sugar. It's sweetened with 2 bananas and just a touch of maple syrup, plus we have some extra nutrients from the zucchini. This loaf is what I call a dessert with benefits!

    Why This Recipe Is Dietitian Approved

    1. Blender recipe. You don't need to spend time shredding zucchini, all you need is a blender. We're keeping this recipe really easy!
    2. Hidden veggies. Zucchini is an excellent source of fibre and vitamin C. You can't even taste it in this chocolate chip zucchini loaf and it adds lots of moisture.
    3. Gluten and dairy-free. This flourless loaf uses oats so it's great for those with gluten restrictions. You can also keep it dairy-free by using vegan chocolate chips.

    Ingredients

    Ingredients including bananas, eggs, oats, chocolate chips, maple syrup, seasoning.

    Banana. We use two bananas for their natural sweetness. Try to wait until your bananas are as RIPE as possible for the best texture and flavour.

    Zucchini. You can’t have zucchini bread without zucchini! You can use yellow or green zucchini (the only difference will be the colour).

    Oats. Instead of flour we use oats as our binder of choice. Oats are a great source of fibre and naturally gluten-free, however I recommend using certified gluten-free oats if you have Celiac disease. Minute, rolled or quick oats all work as we will be blending the batter.

    Eggs. We use two full eggs to bind this loaf and give it rise.

    Spices. Salt and cinnamon are the only spices you need for this recipe.

    Vanilla extract. For additional flavour! Pure natural vanilla extract or artificial vanilla will both work.

    Maple syrup. For natural sweetness, I recommend using pure 100% maple syrup. I have not tried this recipe using any other sweetener.

    Chocolate chips. You can always omit these for a plain zucchini loaf, but I think it's so much better with chocolate chips.

    The complete ingredient list with measurements can be found in the recipe card below. 

    Instructions

    1. Preheat the oven to 350 F and grease a 8-½ x 4-½ x 2-½ inch pan.
    Blending the batter for a zucchini loaf.
    1. In a high powered blender combine zucchini, bananas, eggs, maple syrup, vanilla extract, oats, cinnamon, baking soda and salt. Blend until smooth. You may need to use a spoon or spatula to gently stir periodically to ensure everything gets blended.

    1. Bake for about 40-50 minutes or until a toothpick inserted into the center of the loaf comes out clean. Allow to cool before slicing. 

    Substitutions and Variations

    To make gluten-free: use certified gluten-free oats.

    To make dairy-free: use dairy-free chocolate chips.

    To make vegan: I have not tested this recipe using a flax egg or any type of egg substitute. If you decide to try, please let me know how it goes.

    To make nut-free: this recipe is naturally nut-free.

    Oats can be replaced with 2 cups of pre-blended oat flour. I have not tested this recipe using any other flour variation.

    If you wish to shred the zucchini first you can, just don't ring out the excess water.

    Feel free to switch up the mix-ins in this recipe. This zucchini loaf would also be delicious with chopped nuts or seeds.

    Equipment

    • Blender
    • Mixing bowl

    Storage

    This chocolate chip zucchini loaf can be store on the counter in an airtight container or wrapped tightly with plastic wrap for up to 3 days.

    For longer storage, the loaf can be stored in the fridge for up to 7 days or the freezer for up to 3 months.

    To defrost, simply allow the loaf to thaw in the fridge overnight before slicing. To freeze individual slices, wrap each slice with plastic wrap and freeze.

    Top Tips for Success

    If you wish to avoid the slightly green tinge this bread will have, I recommend using yellow zucchini (summer squash).

    For best results when blending, add the wet ingredients FIRST before adding the oats.

    For the sweetest flavour, use ripe bananas that have brown spots. However I don't recommend using previously frozen bananas as they tend to add too much additional moisture.

    For the best eating experience, I highly recommend serving warm with butter or peanut butter.

    Frequently Asked Questions

    Can I sub the oats for all purpose flour?

    I haven't tried it. If you do, leave me a comment below how it went!

    Does this zucchini loaf taste like banana bread?

    As we are using bananas for majority of the sweetness, they do tend to bring a banana bread-flavour to this loaf! Who doesn't want a moist and flavorful slice of banana bread... but with some hidden veggies!?

    Can you taste the zucchini in this recipe?

    You cannot! The beauty of baking with zucchini is it has such a mild flavour it's so easy to mix it into any recipe. This loaf takes on the flavour of the cinnamon, banana and maple syrup but brings such a nice moist texture thanks to the zucchini!

        Hmm you should be able to however the batter might not be quite as smooth, so I recommend just allowing it to process for a bit longer!

      This morning I said "what can I make with two bananas and a zucchini" and then I found this recipe so it was clearly meant to be, and man is this one a winner. I only have the mini kitchen aid food processor and couldn't fit everything together so I blended the oats first, mixed them with the other dry ingredients in a bowl then blended the zucchini, eggs and banana and mixed it all together (I almost just stirred in the eggs but glad I didn't - blending them make the batter nice and fluffy). I also ignored the comment above and used frozen bananas because that's what I had and it turned out great. I did lower the temp and cook for 10 extra minutes just in case to account for extra moisture. SO good and it took me under 15 minutes to get in the oven. Next time I will mix the chocolate through so you get some in every bite but it does look so nice all sprinkled on top. This recipe feels very forgiving so I am excited to play around with other variations!
