Ingredients You’ll Need

1 cup butter, softened: Provides richness and moisture—make sure it’s at room temperature for easy blending.
3 1/2 cups powdered sugar: Essential for the buttercream frosting; it gives a sweet and creamy finish.
Juice of 1 lemon: Brightens the cake and the frosting; feel free to use more to taste.
1 tsp vanilla: Adds depth of flavor; opt for pure vanilla extract for the best results.
Zest of 1 lemon: Enhances the lemon flavor and adds a delightful fragrance.
2 cups zucchini, shredded: Keeps the cake moist—use fresh zucchini, and don’t worry about peeling it.
3 large eggs: They bind everything together and add to the cake’s structure.
1 cup vegetable oil: Keeps the cake tender and fluffy; you can use melted coconut oil if you prefer.
3 tsp vanilla: Adding extra vanilla boosts flavor; just make sure not to go overboard with it.
2 1/4 cups granulated sugar: Sweetens the batter—this also helps with golden caramelization.
3 cups flour: All-purpose flour provides the cake’s structure; you can substitute with a gluten-free blend if needed.
1 tsp salt: Enhances flavor and balances the sweetness.
1 tsp baking powder: Helps the cake rise, ensuring a lovely, fluffy texture.
1/4 tsp baking soda: Works alongside baking powder for leavening; a little goes a long way.
1 pint fresh blueberries: Juicy, fresh blueberries are the star of this cake—frozen can be used in a pinch but may lead to a more wet texture.

How to Make Blueberry Zucchini Cake

Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Spray a 9 x 13 pan with non-stick cooking spray and set aside. This step ensures the cake won’t stick.
Grate Zucchini: Grate fresh zucchini until you accumulate 2 cups. Set this aside since it adds moisture and a subtle flavor to your cake.
Mix Wet Ingredients: In a large bowl, whisk together 3 large eggs, 1 cup vegetable oil, 3 tsp vanilla extract, and 2 1/4 cups granulated sugar. Once they’re well combined, gently fold in the shredded zucchini; this helps maintain the moisture.
Whisk Dry Ingredients: In a separate bowl, combine 3 cups all-purpose flour, 1 tsp salt, 1 tsp baking powder, and 1/4 tsp baking soda. Whisk these together to evenly distribute the leavening agents.
Combine Mixtures: Slowly add the dry ingredients into the wet mixture, stirring until just combined. Overmixing can lead to a dense cake, so stop once you see no dry flour.
Add Blueberries: Fold in 1 pint of fresh blueberries. Be gentle, so they don’t burst and lose their beautiful shape.
Pour Batter into Pan: Distribute the cake batter evenly into the prepared pan. It should look full and gorgeous.
Bake: Place it in the preheated oven for 50-55 minutes, or until a toothpick inserted into the center comes out clean. The top should be slightly golden and fragrant.
Cool the Cake: Once baked, let the cake cool in the pan for at least 30 minutes while you prepare the frosting.
Make Buttercream: In a clean bowl, mix together 1 cup softened butter and 3 1/2 cups powdered sugar until creamy. Add in the juice of 1 lemon and 1 tsp vanilla extract, mixing until it becomes fluffy and spreadable. Finish by stirring in the zest from 1 lemon.
Frost the Cake: Once completely cool, spread the buttercream evenly over the top of the Blueberry Zucchini Cake, letting it shine.

Storing & Reheating

To keep your Blueberry Zucchini Cake fresh, store it at room temperature in an airtight container for up to 3 days. If you want to prolong its shelf life, refrigerate it for about a week. For a long-term option, freeze the cake (without frosting) for up to 3 months. Just wrap it tightly in foil or plastic wrap. To reheat, pop it in a 350°F (175°C) oven for about 10-15 minutes until warm. The texture may slightly change over time, but a quick warm-up revives its delightful flavors.

Chef’s Helpful Tips

Avoid Overmixing: Mix the wet and dry ingredients just until combined to prevent a dense cake.
Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for better texture.
Fresh Zucchini: Always choose firm, fresh zucchini for the best flavor and moisture.
Nuts Optional: If desired, add 1 cup of chopped walnuts or pecans for a delightful crunch.
Lemon Variations: For an enhanced lemon flavor, try using lime or orange zest/juice instead!
Make Ahead: You can bake the cake a day in advance to let flavors meld beautifully.
