Ingredients for a delicious homemade zucchini cake

This rich yummy cake is made with zucchini, eggs, flour, sugar, vegetable oil, cinnamon, and black walnuts. It’s made even more delicious with a frosting made with cream cheese, butter, sugar, and vanilla extract. The finishing touch is a garnish of toasted black walnuts.

Zucchini Cake Recipe Tips for the Cook

  • Allow your ingredients to warm up to room temperature. Eggs taken out of the refrigerator can be brought to room temperature by placing them in a warm water bath for about 10 minutes.
  • Black walnuts can be hard to find. You can substitute regular walnuts or pecans.
  • For a gluten-free cake, change the flour to rice flour. Or, use gluten-free self-rising flour (and omit the baking powder and soda).
  • You can reduce the sugar by substituting maple syrup in the cake and halving the sugar in the frosting. 
  • You can also opt for coconut oil instead of vegetable oil. 
  • If you prefer a single-layer zucchini sheet cake, use a 9 x 13-inch pan
  • If you want to bake your cake in a 10-inch tube or bundt  pan, you will need to increase the bake time. It will take approximately 1 hour.

How to Prepare Zucchini for the Cake

Grating the zucchini for your cake ensures you will have moisture in every single bite. Use the larger side of a box cheese grater to shred your zucchini. Do not squeeze it or drain it to remove any of the moisture; you want it to make the cake moist!

  • Although you don’t taste the zucchini, its addition is the secret to keeping this cake so incredibly moist!
