One Bowl Zucchini Bread with Coconut Sugar

Making Easy One Bowl Zucchini Bread

That first smell of cinnamon and toasted coconut oil hitting the air is the best part of August. I remember the year my garden went wild, and I had zucchini the size of baseball bats growing every single day.

I wanted something I could throw together for a casual Sunday brunch without spending an hour scrubbing mixing bowls.

This One Bowl Zucchini Bread solves that problem. It's the kind of loaf you bake when you want the house to smell like a bakery but don't actually want to do the work of one. You just mix, bake, and let the oven do the heavy lifting.

You can expect a loaf that's dense but not heavy, with a richness that comes from the coconut oil. It's a reliable treat that doesn't require a fancy mixer or a dozen different tools. Just one big bowl and a spatula.

Why the Batter Stays Light

Mixing everything in one spot prevents us from over working the flour. This keeps the bread tender instead of tough.

How the Moisture Balances

The ratio of coconut oil to grated zucchini prevents the loaf from becoming soggy. It creates a moist crumb that doesn't feel wet.

Quick Recipe Specs

Here are the key details. This recipe is scaled for a standard loaf, but the real advantage of a One Bowl Zucchini Bread is its flexibility. Prep is minimal, which is great if you're short on time.

The total time is 70 minutes, most of which is spent baking. I've found that coconut sugar provides a deeper, more caramelized color than white sugar, giving it a polished, professional look even if you only spent ten minutes on the prep.

Since oven temperatures can vary, I suggest using a thermometer to ensure you're actually reaching 350°F.

Shopping List Breakdown

I use coconut sugar here to bring in a subtle caramel essence. For a different twist, try my Greek Yogurt Zucchini Bread if you prefer a tangier taste.

What Each Ingredient Does

The Full List

• 1 ¾ cups (220g) all purpose flour Why this? Ensures a classic tender crumb and steady structure.
• ¾ cup (150g) coconut sugar Why this? Offers a deeper color and a lower glycemic index than white sugar.
• 1 tsp (5g) baking soda Why this? Works with the zucchini's acidity to help the bread rise.
• ½ tsp (3g) baking powder Why this? Adds an extra boost for a lighter, airier texture.
• ½ tsp (3g) sea salt Why this? Enhances all the other flavors by cutting through the sugar.
• 1 tbsp (6g) ground cinnamon Why this? Gives the recipe its characteristic warm taste.
• ½ cup (120ml) melted coconut oil Why this? Maintains a moist texture for a longer period than butter does.
• 2 large eggs Why this? Acts as a binder and supports the overall structure.
• 1 tsp (5ml) vanilla extract Why this? Complements the cinnamon and sugar for a deeper flavor.
• 2 cups (240g) grated zucchini Why this? Essential for adding nutrients and natural moisture.
• ½ cup (60g) chopped walnuts Why this? Provides a nice textural contrast to the soft bread.

Ingredient Swaps

Equipment Needed

While you don't need fancy gear, a few particular tools make the job easier. I recommend a large mixing bowl (about 4 or 5 quarts) so you have enough space to fold in the zucchini without any spills.

A box grater is the traditional choice for the zucchini, but a food processor with a grating attachment is a huge help for multiple loaves. Just be careful not to over process them into a mush.

A silicone spatula is essential. If you use a whisk for the final fold, you risk over mixing the batter and creating a tough, rubbery bread. The spatula allows for a gentle lift and-turn motion.

A 9x5 inch loaf pan is the ideal size. If you only have an 8x4, your bread will be taller and might need an extra 5-10 minutes in the oven.

Key Steps

Phase 1: The Setup

1. Set your oven to 350°F (175°C).
2. Prepare a 9x5 inch loaf pan by greasing it or using parchment paper. Note: Parchment makes it much simpler to lift the bread out without it breaking.

Phase 2: The One Bowl Blend

3. In a large bowl, whisk the all purpose flour, coconut sugar, baking soda, baking powder, salt, and cinnamon. Whisk until smooth to ensure the baking soda is evenly distributed.
4. Make a well in the center of the dry ingredients.
5. Pour in the melted coconut oil, eggs, and vanilla extract.
6. Stir with a spatula until just combined. Stop once the flour streaks vanish to avoid overworking the gluten.

Phase 3: The Final Fold

7. Gently fold in the grated zucchini and chopped walnuts. Stir until the green shreds are distributed evenly but do not over mix.
8. Transfer the batter into the prepared pan and smooth the top with a spatula.

Phase 4: The Bake & Cool

9. Bake for 55–65 minutes. Wait for the top to reach a deep mahogany brown and a toothpick inserted into the center comes out clean.
10. After 10 minutes of cooling in the pan, transfer the bread to a wire rack.

Avoiding Kitchen Disasters

One mistake I once made was skipping the cooling period in the pan. If you try to flip a hot One Bowl Zucchini Bread onto a rack immediately, the steam is still settling, and the loaf can crack right down the middle.

Fixing a Gummy Center

This usually happens if the oven temperature is too low or the loaf was pulled out too early. Use a digital thermometer to check the center; it should hit 200°F (93°C).

If the top is already dark but the center is raw, tent it with foil and bake for another 10 minutes.

Stopping the Middle Sink

A sunken middle is often a sign of too much moisture or over mixing. Ensure you aren't stirring the batter after the zucchini is in. Also, avoid squeezing the zucchini too much or too little; just grate it and toss it in.

Preventing Dark Tops

If your loaf is browning too fast but feels soft inside, your oven rack might be too high. Move the pan to the center rack. You can also loosely cover the top with aluminum foil after 40 minutes to stop the browning while the center finishes.

Variations & Substitutions

If you want to change the flavor profile, you can easily swap the walnuts for chocolate chips. In fact, if you're craving something richer, I highly recommend my Double Chocolate Zucchini Bread recipe for a fudgy version.

For a different size, you can divide the batter into mini loaf pans. This reduces the bake time significantly, usually down to 30-40 minutes. Just keep an eye on them starting at the 30 minute mark.

You can also add a pinch of nutmeg or a dash of ginger to the dry ingredients. This gives the bread a more "spiced" feel that works great during the winter months.

Freezing and Reheating Guide

The flavor actually improves by the second day. As the zucchini's moisture integrates with the flour, the crumb becomes more cohesive. Keep the loaf at room temperature in a sealed container for as long as 3 days.

If you need it to last longer, the freezer is the way to go. Slice the bread first, wrapping each piece individually in parchment paper before sliding them into a freezer bag. This prevents the slices from freezing together and makes it easy to grab just one.

For the best texture, skip the microwave when warming. Instead, use a toaster or toaster oven until the edges are crisp. This revives that "freshly baked" scent and allows the coconut oil to sizzle slightly.

To minimize waste, don't discard the zucchini peels if you're using a peeler. You can dehydrate them or add them to a homemade vegetable stock for extra nutrients.

How to Serve and Enjoy

I love serving a thick slice of this bread toasted with a smear of salted butter. The salt cuts through the sweetness of the coconut sugar and highlights the cinnamon.

For a more substantial breakfast, pair it with a poached egg and some sliced avocado. The savory elements contrast the sweetness of the bread, making it feel like a full meal.

If you're serving it for a party, slice it into thin rounds and arrange them on a platter with a side of honey whipped ricotta. It turns a simple homemade loaf into something that feels a bit more intentional.

Since this is a healthy One Bowl Zucchini Bread, it also works well as a midday snack. Just keep it in a lunchbox, and it stays moist for hours without needing refrigeration.
