Chocolate chip zucchini bars are my favorite answer to those late summer weeks when zucchini just keeps coming from the garden. The bars turn out unbelievably tender and cake-like and every bite is filled with melting chocolate. This recipe solves the what do I do with all this zucchini puzzle while still feeling like a treat for both kids and adults.
The first time I made these was after a neighbor dropped off a basket of zucchini on my porch. The bars magically disappeared in one afternoon at our family picnic and now they are a summer tradition around here.
Ingredients
- All purpose flour: essential for the sturdy structure and soft crumb always sift for best results
- Ground cinnamon: lifts the flavors with a gentle warmth look for fresh aromatic cinnamon for extra flavor
- Baking powder: key for lift and a fluffy texture always double check it is fresh
- Salt: brightens all the other flavors use fine sea salt for even mixing
- Granulated sugar or Splenda blends: provides sweetness and moisture I like to rub it with my fingertips to break any clumps
- Vegetable oil: delivers moistness choose a mild light oil for best crumb
- Large eggs: hold everything together fresh eggs help the batter set properly
- Finely shredded zucchini: keeps bars moist and sneaks in veggies choose small or medium zucchini for sweeter taste and fewer seeds
- Chocolate chips: every bite needs a sprinkle of chocolate use mini or regular chips and go for good quality
Instructions
- Preheat and Prep:
- Set your oven to 350 degrees Fahrenheit right from the start so it has time to properly come to temperature Grease your jelly roll pan with butter or baking spray making sure you get all the corners for easy release later
- Mix Dry Ingredients:
- In a medium bowl whisk together flour cinnamon baking powder and salt Spend an extra minute here for even distribution which helps every bite taste great
- Combine Wet Ingredients:
- In a large bowl mix the sugar oil and eggs Stir until the sugar dissolves and the mixture looks smooth and thick This step ensures no gritty bits and a fluffy crumb
- Blend Wet and Dry:
- Add the dry ingredients to the wet mixture and gently stir until you see almost no flour streaks Big wooden spoons work well for this be gentle to keep the bars tender
- Fold in Zucchini and Chocolate Chips:
- Take your shredded zucchini and squeeze out excess liquid with a paper towel Mix it in evenly to avoid wet spots Add the chocolate chips and fold until everything looks evenly distributed
- Spread in Pan:
- Pour the batter into your prepared pan and use a spatula to smooth the top into an even layer This ensures every bar bakes at the same rate
- Bake to Perfection:
- Slide the pan into the oven and bake for 28 to 35 minutes Check by inserting a toothpick in the center when it comes out mostly clean with a crumb or two they are done
- Cool and Slice:
- Let the pan cool completely on a rack before slicing into bars This keeps them from crumbling and makes neat squares for serving

Chocolate chips steal the show in every batch and kids line up for the gooey bites Sometimes we save a handful of chips just for scattering on top before baking which always leads to plenty of excitement at the kitchen counter.
Storage Tips
You can keep these bars in an airtight container at room temperature for up to two days They stay moist thanks to the zucchini If you have leftovers or want to make a batch ahead freeze them by placing slices in a single layer in a freezer bag Lay parchment between layers to keep them from sticking Simple defrost at room temperature or warm slightly in the microwave for fresh out of the oven goodness
Ingredient Substitutions
If you are low on oil try using applesauce for half the amount and it keeps the bars extra soft Swap in whole wheat pastry flour to bring a heartier bite If regular chocolate chips are all you have use those white chocolate or even butterscotch chips work in a pinch

These bars popped up as a way to use every last zucchini from summer gardens but the chocolate chip twist turns them into a crowd pleaser that works year round Whenever summer zucchini hits its peak we start doubling the recipe and letting everyone in the family help shred and stir
