Description

Cinnamon Zucchini Coffee Cake — a tender, cinnamon-scented breakfast cake studded with shredded zucchini. When zucchini bakes with cinnamon and sugar it takes on a warm, almost-apple sweetness.


Ingredients

Scale

For the cake

  • 1½ cups (186 g) all-purpose flour
  • 2 teaspoons baking powder
  • 1 teaspoon ground cinnamon
  • ½ teaspoon fine salt
  • ¾ cup (150 g) granulated sugar
  • ¼ cup (60 ml) vegetable oil (or other neutral oil)
  • 1 large egg
  • ½ cup (118 ml) milk (dairy or plant-based)
  • 2 cups (about 206 g) shredded zucchini (roughly 1 large or 2 small zucchinis)

For the streusel

  • ½ cup (100 g) packed brown sugar
  • 1 tablespoon (8 g) all-purpose flour
  • 1 teaspoon ground cinnamon
  • 2 tablespoons (28 g) melted butter


Instructions

  1. Preheat the oven to 350°F (175°C). Grease an 8-inch or 9-inch square baking pan (or line it with parchment).
  2. In a medium bowl, whisk together the flour, baking powder, cinnamon, and salt until evenly combined.
  3. In a large mixing bowl, beat the granulated sugar, vegetable oil, and egg until smooth. Pour in the milk and mix to combine.
  4. Add the dry mixture to the wet ingredients and stir gently just until the batter comes together — don’t overmix.
  5. Fold the shredded zucchini into the batter until distributed evenly. Transfer the batter to the prepared pan and spread it into an even layer.
  6. Make the crumb topping: in a small bowl, combine the brown sugar, tablespoon of flour, and cinnamon. Stir in the melted butter until the mixture forms coarse crumbs. Scatter the streusel evenly over the cake batter.
  7. Bake for 30–35 minutes, or until a thin skewer or toothpick inserted into the center comes out clean or with only a few moist crumbs attached.
  8. Let the cake cool slightly in the pan on a wire rack before slicing. Serve warm or at room temperature.

Notes

Notes: Use a box grater to shred the zucchini; no need to squeeze out moisture unless it seems very wet. If you prefer a deeper streusel, double the topping ingredients. If the top browns too quickly, tent loosely with foil for the final 5–10 minutes of baking.
