🍽️ How to Make Chocolate Zucchini Bars
🔪 Step 1: Prep and Preheat
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
🥄 Step 2: Combine Dry Ingredients
In a medium bowl, whisk together:
-
Flour
-
Cocoa powder
-
Baking soda
-
Salt
-
Cinnamon
Set aside.
🥒 Step 3: Mix Wet Ingredients
In a large mixing bowl:
-
Beat together the applesauce, oil, and sugar until smooth.
-
Stir in vanilla extract.
-
Fold in the grated zucchini.
🍫 Step 4: Combine and Stir in Add-ins
Gradually stir the dry mixture into the wet zucchini mixture until fully incorporated. Do not overmix.
Then fold in:
-
Chocolate chips
-
Walnuts (if using)
🔥 Step 5: Bake
Pour the batter into your prepared pan and smooth the top with a spatula. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with moist crumbs (not wet batter).
❄️ Step 6: Cool and (Optional) Glaze
Let the bars cool completely before slicing. If using the glaze, whisk ingredients in a bowl and drizzle over cooled bars.
✅ Tips for Success
Use Fresh Zucchini
Fresh zucchini is crucial for moisture. Don’t squeeze it dry unless it’s extremely watery.
Don’t Overbake
The key to fudgy bars is pulling them from the oven just as the center sets. They’ll continue to firm up as they cool.
Make It Vegan
Replace brown sugar with organic cane sugar, and use dairy-free chocolate chips. Swap eggs (if using) with flax eggs if adapting the recipe further.
🔄 Substitutions and Variations
-
Oil-Free: Replace oil with more applesauce or mashed banana.
-
Gluten-Free: Use a 1:1 gluten-free flour blend.
-
Nut-Free: Skip the walnuts or sub with sunflower seeds.
-
Extra Chocolatey: Add a swirl of chocolate hazelnut spread on top before baking.
❓ Frequently Asked Questions (FAQs)
Q1: Can you taste the zucchini?
No. Zucchini adds moisture and nutrition but is completely neutral in flavor. It blends into the chocolate beautifully.
Q2: Do I need to peel the zucchini?
Not at all. The skin is soft and unnoticeable in the final product, and it adds nutrients and color.
Q3: Can I freeze chocolate zucchini bars?
Yes! After cooling, slice and wrap each bar individually. Freeze for up to 3 months. Thaw at room temperature or microwave for 20–30 seconds.
Q4: How do I store these bars?
Store in an airtight container at room temperature for up to 3 days or in the fridge for up to a week. They get even fudgier the next day!
Q5: Can I make this recipe sugar-free?
You can try using a sugar substitute like monk fruit sweetener or stevia, though texture and moisture may vary. Test in small batches for best results.
