Gluten-Free Vegan Pantry Essentials for Baking

Here’s what you’ll want to stock up on for consistently good results:

  • Gluten-free flour blend: Look for blends containing rice flour, potato starch, and/or tapioca starch for a springy, cake-like crumb.
  • Ground walnuts or almonds: Contribute richness and structure.
  • Cocoa powder: Choose unsweetened for deep chocolate flavor.
  • Plant-based milk: Almond, soy, or oat all work well—go for unsweetened and plain versions.
  • Maple syrup or agave for sweetening.
  • Baking powder and baking soda: Ensure both are certified gluten-free if needed.
  • Apple cider vinegar: Balances flavors and helps baking soda leaven the bread.
  • Vegan chocolate chips: Check labels for gluten and dairy-free certifications.

Step-by-Step Method

  1. Prep your pan:
    • Use a one-pound loaf tin. Line with greased parchment paper for easy removal.
  2. Prepare your zucchini:
    • Grate with a box grater. Squeeze out as much water as possible using a clean tea towel or cheesecloth; this prevents sogginess.
  3. Mix your dry ingredients:
    • Whisk together the gluten-free flour, ground walnuts, cocoa powder, baking powder, baking soda, and salt in a large mixing bowl.
  4. Stir in wet ingredients:
    • In a separate bowl, combine plant-based milk, maple syrup, coconut oil, apple cider vinegar, and grated zucchini.
    • Mix until everything is thoroughly incorporated.
  5. Combine and fold:
    • Add the wet mixture to the dry ingredients. Stir until just combined—do not overmix.
  6. Fold in chocolate chips:
    • Gently mix vegan chocolate chips into the batter.
  7. Bake:
    • Scrape batter into prepared loaf tin, smoothing the top.
    • Bake in a preheated oven at 350°F (175°C) for 35–55 minutes (check at 35, may take up to 1 hour depending on oven and moisture of zucchini).
    • The bread is done when a toothpick inserted comes out mostly clean (a few moist crumbs are fine).
  8. Cool:
    • Let cool in pan for 15 minutes, then carefully transfer to a wire rack to cool completely.

Top Tips for Perfect Gluten-Free Vegan Zucchini Bread

  • Squeeze your zucchini well: Extra moisture will make the bread dense and gooey.
  • Don’t over-mix: Gluten-free batters can become gummy when over-stirred.
  • Let cool before slicing: Warm bread is fragile; allow to cool for clean slices.
  • Storage: Keep leftovers covered at room temperature for 2 days or refrigerate for up to 5 days. Freeze slices for longer storage—reheat in a toaster or microwave as needed.

Key Variations and Customizations

  • Nut-free: Swap ground walnuts for ground sunflower seeds or oat flour, and use nut-free plant milk.
  • Refined sugar-free: Ensure chocolate chips and other components are sweetened with unrefined sugars.
  • Double chocolate: Add extra chips or a chocolate glaze after baking. Optional: sprinkle finely chopped chocolate on top before baking for a crinkly crust.
  • Add-ins: Mix in dried cranberries, chopped pecans, or a hint of espresso powder for complexity.

Troubleshooting Common Issues

ProblemPotential CausesSolution

Nutritional Benefits

  • Zucchini is a source of hydration, fiber, and vitamins

  • Cocoa powder offers antioxidants and adds rich flavor with fewer calories than chocolate bars
  • Plant-based ingredients support a heart-healthy, lower-cholesterol diet

Frequently Asked Questions

Can I use a different flour blend?

Yes. You can swap in any reliable gluten-free all-purpose flour, or use a combination of oat flour and almond flour for added flavor—just note that results may vary slightly in texture and moisture depending on the blend.

Do I have to peel the zucchini?

No, peeling isn’t required. The skin adds color, fiber, and nutrition, and once baked you won’t notice it in the finished bread.

Will the final bread taste like zucchini?

No. The chocolate flavor takes center stage; the zucchini simply brings a tender, moist crumb.

How do I make it soy-free/nut-free?

For soy-free, select a soy-free plant milk (like oat or almond). For nut-free, use ground sunflower seeds instead of nuts and choose oat or coconut milk. Double-check that your chocolate chips are allergen-friendly.

Can I freeze gluten-free vegan chocolate zucchini bread?

Absolutely. Wrap tightly in plastic wrap or freeze slices individually in bags for up to 2 months. Defrost at room temperature or using a toaster.

Expert Tips for Success

  • Use a kitchen scale for precision—especially important in gluten-free baking.
  • Cool cake completely before adding glaze or slicing, as gluten-free baked goods can be fragile when warm.
  • For a crackly top, don’t overwork the surface.
  • Mix-ins: Mini vegan marshmallows or crushed freeze-dried raspberries add a fun twist.
