Snack time!

This cinnamon swirl zucchini bread is well-spiced, very moist and absolutely satisfying. It’s a lovely snack and a delicious excuse to enjoy cake for breakfast.

If you’ve got an abundance of zucchini, this is a perfect use for at least one of them. You can easily double or triple the recipe to make multiple loaves to share.

I’ve been making a favorite zucchini bread recipe for years, often stirring in or topping with chocolate chips for my kids. They tend to be wary of the green flecks, so a few chips makes the loaf more appealing to them. But I wanted a classic cinnamon quick bread twist—coffee cake or cinnamon swirl flavors are always a favorite.

The change is small and easy: mix a cinnamon-sugar blend and sprinkle it on the batter halfway through, then again on top. It creates a beautiful swirl and adds that warm, cozy cinnamon flavor throughout.

One tip: I usually don’t squeeze all the moisture out of the grated zucchini. Leaving some of that liquid in keeps the bread extra tender and moist—exactly what you want in a quick bread.

We love having quick bread on hand; it feels nostalgic and comforting. Even though it’s a treat, it’s a satisfying, home-baked snack that tastes like childhood and warm kitchens.

Tastes like the warm, cozy months to come!
