Key Ingredients for Blueberry Zucchini Cake
Gather these simple ingredients for this tasty cake:
- 3 eggs, lightly beaten
- 1 cup vegetable oil
- 3 tsp vanilla extract
- 2 1/4 cups sugar
- 2 cups zucchini, peeled, grated, and drained
- 3 cups all-purpose flour
- 1 tsp salt
- 1 tsp baking powder
- 1/4 tsp baking soda
- 1 pint fresh blueberries (reserve some for garnish)
How to Make Blueberry Zucchini Cake
Preparing the Cake Batter
Start by preheating your oven to 350°F and preparing two 8-inch round cake pans. Grate the zucchini and wrap it in a clean towel to wring out any excess liquid. In a large bowl, beat together the eggs, oil, vanilla, and sugar until smooth. Gently fold in the drained zucchini.
Baking the Zucchini Cake
Gradually add the flour, salt, baking powder, and baking soda to the mixture. Then, gently fold in the fresh blueberries, being careful not to crush them. Divide the batter evenly between the prepared pans and tap them on the counter to release any air bubbles. Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean.
Making the Lemon Buttercream Frosting
While the cakes cool in their pans for 20 minutes, you can prepare the lemon buttercream. Beat the butter and salt in a bowl until creamy. Gradually mix in powdered sugar, half a cup at a time, until smooth. Then, add the lemon juice, zest, vanilla, and optional yellow food coloring. Beat on medium-high speed for 3-5 minutes until the frosting is light and creamy.
Assembling and Frosting Your Cake

Once the cakes have cooled completely, place one layer on a serving plate. Spread a generous amount of lemon buttercream on top, then add the second layer. Finish by frosting the top and sides of the cake with the remaining lemon buttercream. Garnish with reserved blueberries for an extra pop of color!
Tips for the Perfect Blueberry Zucchini Cake
Zucchini Preparation Tips
Make sure to properly drain the grated zucchini. This step prevents the cake from becoming too moist and ensures a fluffy texture.
Preventing Sinking Blueberries
To avoid sinking blueberries, dust them lightly with flour before folding them into the batter. This simple trick helps keep them suspended during baking.
Blueberry Zucchini Cake Variations
For an extra flavor boost, consider adding a layer of blueberry preserves between the cake layers before frosting. It adds a delightful burst of flavor and makes every bite even more amazing.
Storing Your Blueberry Zucchini Cake
Store any leftover blueberry zucchini cake in the refrigerator due to the butter and moisture content. Allow it to come to room temperature for 5-10 minutes before serving to enhance the flavor and texture.
