Expert recipe tips:

Here are my top six tips and tricks to making the very best, moist, and rich chocolate banana bread:

Remove excess liquid from the zucchini: This is my #1 tip. Be sure to squeeze excess moisture from the shredded zucchini to prevent a soggy loaf.
Don't over-mix the batter: To ensure your chocolate banana bread is light and fluffy, gently fold your dry ingredients and wet ingredients with a spatula or wooden spoon. Overmixing your batter is a big no-no.
Use overripe spotty brown bananas: Using bananas with lots of brown spots is vital for this recipe! It makes this banana zucchini bread sweet without adding cane sugar.
Watch the clock, and don't overbake. Bake your super moist chocolate banana bread until a toothpick comes out clean.
Enjoy it the next day. Banana bread is always best the day after you bake it. Trust me on this!
Use homemade oat flour: Make your oat flour by blending oats until fine, or use store-bought oat flour.

Turn this banana bread recipe into muffins:

Here are instructions on how to turn this chocolate zucchini banana bread into muffins:

Line a muffin tin with 12 paper or silicone liners.
Prepare batter the same way as instructed.
Evenly divide the batter into each muffin liner.

Frequently Asked Questions

Can I taste the zucchini in zucchini banana bread?

You can't taste the zucchini in this chocolate zucchini banana bread. It blends seamlessly with the other ingredients, adding moisture and nutritional value without altering the flavor. This double chocolate banana bread lasts like a fudgy brownie.

Can I add mix-ins?

Yes, feel free to add ½ cup of chopped walnuts, pecans, cashews, peanuts, or almonds to the batter. You can even experiment with ⅓ cup of shredded coconut.

Can I make this chocolate banana bread gluten-free?

You can substitute white whole wheat flour with gluten-free 1:1 baking flour. Oat flour is already gluten-free.

Why did my zucchini banana bread sink in the middle?

I bake this recipe a lot. If your bread sinks in the middle, it is likely because you forgot to remove the extra liquid from the zucchini shreds. If you add the zucchini directly to the batter after shredding, there will be too much liquid, and the banana bread won't rise.

Why is my banana bread dry?

Banana bread can be dry for a few reasons. The main two are (1) you overbaked the banana bread, or (2) you added too much flour. Keep an eye on the clock and the banana bread in the oven; every oven is different. Likewise, spoon and level your flour into the measuring cups, and do not scoop from the bag. Also, don't make any flour substitutions for the almond flour.

Can I make banana bread into muffins?

Yes, you can make this banana bread recipe into muffins. Just scroll up for the instructions or find them in the recipe card notes.

Can I freeze chocolate banana bread for later?

Yes, you can freeze chocolate banana bread by allowing it to cool to room temperature, then place individual slices in freezer-safe bags and freeze them for up to 3 months. When ready to enjoy, let it thaw overnight in the fridge or microwave them for 30 - 60 seconds until warm.

How to store leftover chocolate banana bread:

Simply store this banana bread at room temperature for up to 3 days by covering the pan in foil or plastic wrap. It can also be stored in the refrigerator for up to 5 days!
