Cinnamon Zucchini Cake is loaded with zucchini and topped with a cinnamon sugar crackle topping. Perfect way to use up extra zucchini from your garden.
Prep: Preheat oven to 350°F. Grease a 9x13-inch cake pan and set aside. Remove excess liquid from zucchini shreds by pressing with a paper towel. Discard excess liquid.
Combine Wet Ingredients: In a large mixing bowl, combine the brown sugar, melted butter, canola oil, eggs, buttermilk and vanilla extract. Whisk until smooth and completely combined.
Add Dry Ingredients: Add flour, cinnamon, baking soda and salt to liquid mixture. Stir to combine; avoid over-stirring.
Add Zucchini: Gently fold in shredded zucchini and allow the batter to rest for 5 minutes.
Make the Topping: In a small bowl, stir together the topping ingredients (granulated sugar, cinnamon, melted butter, and flour) with a fork until the mixture is coarse and crumbly.
Assemble: Spread the cake batter into the prepared cake pan. Evenly sprinkle the cinnamon-sugar topping across the top of the batter.
Bake: Bake at 350°Ffor 35-40 minutes, or until a toothpick inserted into the center comes out clean and the top bounces back when gently touched. Let cool slightly before slicing.
