Moist zucchini bread topped with a buttery brown sugar oat crumble. This recipe is an easy-to-make, one loaf recipe made with butter instead of oil to give a delicious nutty flavor and tender crumb.
Brown sugar oat crumble:
- 1/3 cup quick or old-fashioned oats
- 1/4 cup Brown sugar
- 1 tablespoon All-Purpose flour
- 1/2 teaspoon Ground cinnamon
- 2 tablespoon Butter, cold & cut into cubes
- 1/2 cup unsalted butter, melted and cooled
- 2 large eggs, room temperature
- 2 teaspoon vanilla extract
- 1 1/2 cup shredded zucchini (about 2 medium)
- 1 3/4 cup All-Purpose flour
- 1/2 cup light brown sugar, lightly packed
- 1/2 cup granulated sugar
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 2 teaspoon Ground cinnamon
- 1 teaspoon Kosher salt
- Preheat oven to 350°F (177°C). Grease an 8.5 x 4.5-inch loaf pan.
Make oat crumble topping:
- In a medium bowl, combine oats, brown sugar, flour, and cinnamon.
- Add cold cubed butter (~1 in./2.5cm) into dry ingredients.
- Using a pastry cutter or your fingers, cut the cold butter into the flour mixture until the mixture resembles a coarse crumb. Set aside.
Make zucchini bread batter:
- In a large bowl, whisk together melted butter, eggs, and vanilla extract until smooth and combined.
- Add in shredded zucchini, mixing until combined.
- In a medium bowl, whisk together flour, brown sugar, granulated sugar, baking powder, baking soda, cinnamon, and salt until combined.
- Add dry ingredients into the wet ingredients, folding until just combined. Don’t overmix - similar to muffins, a couple of small flour strikes in the batter is ok. The batter will be on the thicker side.
- Pour batter into the prepared loaf pan; it should be about ⅔ full. Smooth batter to ensure the batter is level.
- Evenly sprinkle oat crumble on top of the batter until evenly distributed.
- Bake at 350°F (177°C) for 60-70 minutes.
- Remove bread from the oven and place it on a cooling rack. Allow bread to cool completely before serving.
- Recipe update: this recipe has been updated to include cinnamon within the zucchini bread batter ingredients.
- Prepping zucchini: there is no need to peel before shredding. Use a cheese grater or a food processor to shred the zucchini. If your zucchini has excess water, you may see a pool of water in the container you shredded your zucchini. Pour it out and lightly pat with a paper towel. You don't want to squeeze the moisture out, as this is what keeps the bread moist.
- Edges or top browning too quickly: use foil and tent it around the edges of the loaf.
- Checking if bread is done: insert a knife into the middle of the loaf. If it comes out clean or has a couple of moist dull-looking crumbs on it, your bread is done. If it comes out wet, continue baking.
- Removing loaf from pan: before baking, ensure your loaf pan is generously greased. Once done baking, allow the bread to cool in the pan for 10-15 minutes (or cool enough to handle). Release the edges of the loaf with an offset spatula or knife. Carefully turn out onto the cooling rack.
- Storing bread: in an airtight container, bread can be stored up to 2-3 days at room temperature or 1 week in the refrigerator.
