Chocolate Swirl Zucchini Bread with Greek Yogurt

A moist, tender quick bread that cleverly incorporates shredded zucchini for extra moisture while maintaining rich chocolate flavor. The applesauce and Greek yogurt create a lighter texture without sacrificing taste, while warm spices like cinnamon and cloves add depth. The dramatic chocolate swirl running through each slice makes this perfect for breakfast, snack time, or dessert. This recipe produces one generous loaf that slices beautifully and freezes well for future enjoyment.

Tips

Tip 1

Use two 8x4 inch pans instead of one 9x5 inch pan if you prefer smaller loaves with shorter baking time.

Tip 2

Slice and freeze individual portions in sandwich bags for convenient grab-and-go breakfast options.

Tip 3

Don't overmix when creating the swirl pattern - gentle swirls preserve the distinct chocolate and plain layers.

FAQ

Can I use regular yogurt instead of Greek yogurt?

Yes, but Greek yogurt provides thicker consistency and more protein. Regular yogurt may make the batter slightly thinner but will still work well.

How long does this bread keep fresh?

Wrapped tightly, it stays fresh at room temperature for 3 days or refrigerated for 1 week. Individual slices freeze well for up to 3 months.

Can I make muffins instead of a loaf?

Yes, divide batter among 12 muffin cups and bake at 350°F for 18-22 minutes. Create mini swirls in each muffin cup.
