Ingredients and substitutions

Ingredients on a counter top.
  • Zucchini - You'll need 220 grams or 1.5 cups of finely grated zucchini. Do not drain or squeeze the liquid from your zucchini - the liquid adds moisture to your bread. For this recipe, you'll need about 1 to 1.5 medium or 2 small zucchini.
  • Granulated sugar - Adds sweetness and moisture to your bread. This bread is lightly sweetened as written. If you'd like a sweeter dessert bread, the sugar can be increased by ¼ cup.
  • Vegetable oil - Adds moisture to your bread.
  • Eggs - Add moisture and structure to your bread.
  • Vanilla extract - Adds depth of flavor to your bread.
  • All-purpose flour - Adds structure to your bread. I have not tested this recipe with other types of flours, so I don't suggest making any substitutions. Baking is an exact science, and altering main ingredients can change the density and texture of your bread. Instead, search for a recipe that includes the flour you'd like to use.
  • Cocoa powder - I've written this recipe to use natural cocoa powder. Natural cocoa powder is more acidic than Dutch cocoa powder. When paired with the listed leavening agents, you'll get the proper rise.
  • Leavening agents - This recipe uses both baking soda and baking powder. They cannot be substituted for one another - you'll need both for the proper lift.
  • Chocolate chips - The chocolate chips are optional, but add nice melty pockets throughout your bread. Feel free to use milk chocolate, semi sweet chocolate, white chocolate, or peanut butter chips for a unique flavor.

How to make chocolate zucchini bread

Making chocolate zucchini bread in a metal loaf pan.
  1. Add wet ingredients to a large bowl and stir to combine.
  2. Whisk dry ingredients in a separate bowl before stirring into the wet ingredients. Add chocolate chips last, stirring to combine.
  3. Pour into a 9x5 loaf pan and top with more chocolate chips.
  4. Bake until loaf looks set across the top and pops back when gently pressed in the center.

Tips and tricks

Shredding zucchini for bread - I recommend using the small side of a box grater to grate zucchini for baked goods. Finely grated zucchini melts seamlessly into the batter when baked with the only sign of zucchini being the tiny green flecks. The large side of a box grater also works but adds a noticeable texture to your baked bread. Here's the box grater I use: OXO Good Grips Box Grater

Gently mix batter - If the batter is overmixed, the gluten is overworked and your bread can turn out tough. Instead, use a gentle stirring motion with a spoon (no need for a stand mixer or hand mixer) and only stir until ingredients are just incorporated.

Pan size - This recipe makes one 9x5 loaf of zucchini bread. These are the pans I use for all my zucchini bread recipes: Farberware Loaf Pan 9x5, Set of 2

Storage

Zucchini bread can be stored at room temperature for 3 to 4 days in a tightly sealed container.

Zucchini bread can be frozen for up to 6 months in a tightly sealed, freezer-safe container. To thaw a whole loaf, place on the countertop for up to 3 hours to bring to room temperature. Single slices will thaw in about 1 hour or less.

Frequently asked questions

Should I peel my zucchini for zucchini bread?

No, there's no need to peel your zucchini before shredding it for zucchini bread. The skin of the zucchini contains fiber and other nutrients you'd otherwise be missing out on by peeling it off.
Once your bread is baked, the only sign of zucchini is tiny flecks of green throughout. Otherwise, the zucchini (skin included) melts right into the bread.

Should I squeeze the liquid from my zucchini?

No, do not squeeze the liquid from your zucchini. For this particular recipe we're utilizing the liquid in the zucchini to thin the batter slightly and add moisture to the bread.

Can I use cucumber instead of zucchini?

No, zucchini has a mild flavor that makes it ideal for baking. Cucumber has a fresh "melon" flavor that's much more pronounced and not ideal for hiding in baked goods. For more information: Zucchini vs Cucumber - What's the Difference

Troubleshooting

Why is my zucchini bread soggy/sinking in the middle?

If your baked zucchini bread turned out soggy or sinking in the center, then it was either underbaked or had too much moisture. Make sure not to add extra wet ingredients to this recipe, like extra zucchini, a dollop of sour cream, applesauce, or extra vegetable oil. This recipe includes exact measurements of wet and dry ingredients to ensure your bread turns out perfectly baked and moist, not wet or soggy.

Why is my zucchini bread dry?

Dry baked goods can happen for several reasons. Either your bread was overbaked, too many dry ingredients (like flour) were added to the recipe, or the moisture-adding ingredients (eggs, sugar, oil, zucchini) were reduced.

Why is my zucchini bread bland?

Bland baked goods can happen for a few reasons. Omitting the salt, reducing the sugar, or adding too much flour can cause your bread to turn out bland. Salt enhances the flavors of the other ingredients - it's not there to make your bread "salty". Measure flour accurately by weighing it using the gram measurements listed in the recipe card. If you don't have a scale, use the spoon and level method. Gently spoon flour into a measuring cup, then level off the top with a knife. Scooping flour with a measuring cup compacts flour into the cup, adding up to 25% extra flour to the recipe. Decreasing the listed sugar can also make your bread turn out bland (and sometimes dry).
