Ingredients

Units Scale

Streusel

  • 1 cup brown sugar
  • 2 Tablespoons cold unsalted butter
  • 1 Tablespoon all purpose flour
  • 1 1/2 teaspoons ground cinnamon

Cake

  • 2 cups shredded zucchini (from 1 medium zucchini)
  • 1/2 teaspoon salt, divided
  • 2 cups all purpose flour
  • 1/2 cup whole wheat flour (see note*)
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1 1/4 cups granulated sugar
  • 1/3 cup canola oil
  • 1/2 cup plain Greek yogurt
  • 1/2 cup milk
  • 1 large egg, lightly beaten
  • 1 teaspoon vanilla

Instructions

  1. Streusel – Add the brown sugar, flour, butter and cinnamon to the bowl of a food processor. Pulse together until mixture resembles sand. Set aside.
  2. Cake – Toss the zucchini with 1/4 teaspoon of the salt. Let it sit in a small colander to drain.
  3. Meanwhile, grease a 9×13″ rectangular baking pan and heat the oven to 325°F.
  4. Whisk together the all purpose flour, whole wheat flour, baking powder, baking soda, and remaining 1/4 teaspoon of salt in a medium bowl. Set aside.
  5. In a large bowl, whisk together the sugar, oil, yogurt, milk, egg, and vanilla. Fold in the flour mixture until just barely incorporated. Fold in the zucchini until uniform.
  6. Spread half of the batter over the bottom of the greased baking pan. Top with half of the streusel mixture. Carefully, without mixing the streusel mixture into the batter, spread the remaining batter on top of the streusel mixture. Top with the remaining streusel mixture. Bake for 45 minutes, until a toothpick inserted into the center comes out clean. Cool for at least 20 minutes before serving.

Notes

* You can omit whole wheat flour and just use an extra 1/2 cup of all purpose flour, if you wish.
