Ingredients:
For the Cake
Step 1: Preparing the Wet Ingredients and Zucchini
Begin extract by preheating your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or two 8-inch round cake pans. This step is crucial to ensure your cake doesn’t stick. In a large bowl, whisk together the 3 large eggs until lightly beaten. Then, pour in the 1 cup of vegetable oil and 1 tablespoon of vanilla extract. Whisk these wet ingredients together until they are well combined. Next, add the 2 1/4 cups of sugar to this mixture and whisk until everything is thoroughly incorporated and the sugar has started to dissolve. Now, it’s time for our secret ingredient: the zucchini. Make sure your zucchini is washed, trimmed, and then finely shredded using a box grater. You should have about 2 cups of shredded zucchini. Gently fold the shredded zucchini into the wet ingredient mixture. Don’t worry if it looks a little wet; this is exactly what we want for a moist cake.
Step 2: Combining the Dry Ingredients and Incorporating Them into the Batter
In a separate medium bowl, whisk together the 3 cups of all-purpose flour, 1 teaspoon of salt, 1 teaspoon of baking powder, and 1/4 teaspoon of baking soda. Whisking these dry ingredients together ensures that the leavening agents and salt are evenly distributed throughout the flour, which will lead to a consistent rise and flavor in your cake. Now, gradually add the dry ingredients to the wet ingredients. Mix on low speed, or by hand with a spatula, until just combined. Be careful not to overmix at this stage; overmixing can develop the gluten in the flour too much, resulting in a tougher cake. A few small lumps of flour are perfectly fine.
Step 3: Folding in the Blueberries and Baking the Cake
This is where we add those delightful pops of fruity goodness. Take your 1 pint of blueberries and gently toss them with 1 teaspoon of flour in a small bowl. This light coating of flour helps prevent the blueberries from sinking to the bottom of the cake during baking. Now, gently fold the floured blueberries into the cake batter. Again, try not to overmix. Spoon the batter evenly into your prepared baking pan(s). For a 9×13 inch pan, spread the batter out evenly. If using round pans, divide the batter equally between the two. Place the pan(s) in the preheated oven. Bake for 30-40 minutes for a 9×13 inch pan, or 25-35 minutes for round pans, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The baking time can vary depending on your oven, so start checking a little earlier. Once baked, remove the cake from the oven and let it cool in the pan for about 10-15 minutes before inverting it onto a wire rack to cool completely. It’s important that the cake is completely cool before frosting, otherwise, the buttercream will melt.
For the Lemon Buttercream
Step 4: Creaming the Butter and Adding Confectioners’ Sugar
While the cake is cooling, let’s prepare the luscious lemon buttercream. In a large bowl, using an electric mixer, beat the 3/4 cup (1 1/2 sticks) of unsalted butter at room temperature until it is light and fluffy. This usually takes about 2-3 minutes on medium-high speed. Having the butter at room temperature is key for a smooth buttercream. Gradually add the 4 cups of confectioners’ sugar, about a cup at a time, mixing on low speed until each addition is incorporated. Scrape down the sides of the bowl frequently to ensure everything is mixed evenly. As you add the sugar, the mixture will become quite thick.
Step 5: Achieving the Perfect Lemon Flavor and Consistency
Once all the confectioners’ sugar has been incorporated, the buttercream will be very stiff. Now it’s time to add the fresh lemon juice. Start by adding about 2 tablespoons of fresh lemon juice. Mix on medium speed until the buttercream is smooth and creamy. If the buttercream is still too thick, add more lemon juice, a teaspoon at a time, until you reach your desired consistency. You want a spreadable buttercream that isn’t too runny. You can also add a tiny pinch of salt at this stage if you like, as it can help balance the sweetness and enhance the lemon flavor. Taste the buttercream and adjust the lemon juice as needed to achieve your perfect balance of tart and sweet. Once the cake is completely cool, frost the top generously with this delightful lemon buttercream. Slice and enjoy your moist, delicious, and secretly veggie-packed Blueberry Zucchini Cake!

Conclusion:
This Blueberry Zucchini Cake with Lemon Buttercream is a true delight, offering the perfect balance of moist, tender cake and bright, tangy frosting.

Frequently Asked Questions:
Can I use frozen blueberries instead of fresh?
Absolutely! If using frozen blueberries, do not thaw them before adding them to the batter. Simply toss them in a tablespoon of flour with the other dry ingredients to help prevent them from sinking.
My zucchini seems very wet. Should I drain it?
For this particular Blueberry Zucchini Cake recipe, it’s best not to drain the zucchini. The moisture from the zucchini contributes significantly to the cake’s tender and moist crum extractb. Squeezing out the liquid can result in a drier cake.
How long will the Lemon Buttercream frosting last?
The lemon buttercream will last for about 3-4 days when stored in an airtight container in the refrigerator. Allow it to come to room temperature and give it a good whisk before frosting the cake if it has firmed up.
