Cake Instructions:
Prepare the Wet Ingredients and Zucchini: In a large mixing bowl, whisk together the 3 large eggs until they are well combined and slightly frothy. Next, gradually pour in the 1 cup of vegetable oil while continuing to whisk. This helps to emulsify the mixture, ensuring a smooth and evenly hydrated batter. Add the 1 Tbsp of vanilla extract and the 2 1/4 cups of sugar. Whisk everything together until the sugar is mostly dissolved and the mixture is smooth. Now, it’s time for the star of the moistness: the zucchini! Add the 2 cups of shredded zucchini to the wet ingredients. It’s important to shred your zucchini finely; if you have a very watery zucchini, you can gently squeeze out some excess moisture with a paper towel, but often it’s not necessary, as the moisture contributes to the cake’s incredible texture. Stir the zucchini into the wet mixture until it’s evenly distributed.
Combine Dry Ingredients and Add to Wet Mixture: In a separate medium bowl, whisk together the 3 cups of all-purpose flour, 1 tsp of salt, 1 tsp of baking powder, and 1/4 tsp of baking soda. Whisking the dry ingredients together ensures that the leavening agents and salt are evenly distributed, which is crucial for a consistent rise and flavor. Now, gradually add the dry ingredients to the wet ingredients. Mix on low speed or by hand until just combined. Be careful not to overmix at this stage; overmixing can develop the gluten in the flour too much, leading to a tougher cake. A few streaks of flour are perfectly fine, as they will be incorporated as you add the blueberries.
Fold in the Blueberries and Bake: Gently fold in the 1 pint of blueberries, which you should have tossed in 1 tsp of flour beforehand. This initial flour coating helps to prevent the blueberries from sinking to the bottom of the cake during baking. Stir them in until they are evenly scattered throughout the batter. Now, prepare your baking pans. I like to use two 9-inch round cake pans, greased and floured, or lined with parchment paper. Divide the batter evenly between the prepared pans. Smooth the tops with a spatula. Bake in a preheated oven at 350°F (175°C) for approximately 30-35 minutes, or until a wooden skewer or toothpick inserted into the center of the cakes comes out clean. The aroma that fills your kitchen during this time is simply divine!
Cool the Cakes: Once the cakes are baked, remove them from the oven and let them cool in their pans on a wire rack for about 10-15 minutes. This allows the cakes to set up slightly before you attempt to remove them, reducing the risk of breakage. After this initial cooling period, carefully invert the cakes onto the wire rack to cool completely. It’s essential that the cakes are entirely cool before you attempt to frost them; otherwise, the buttercream will melt and slide right off. Patience is key here!
Make the Lemon Buttercream Frosting: While the cakes are cooling, let’s whip up the glorious lemon buttercream. In a large bowl, beat the 3/4 cup (1 1/2 sticks) of unsalted butter with an electric mixer until it’s light and fluffy. Make sure your butter is truly at room temperature; it should yield slightly when pressed. Gradually add the 4 cups of confectioners’ sugar, about a cup at a time, mixing on low speed until it’s incorporated. Once all the sugar is added, increase the speed to medium-high and beat until the frosting is smooth and creamy. Now for the zing! Add fresh lemon juice, a tablespoon at a time, beating well after each addition, until you reach your desired consistency and lemony flavor. You’re looking for a frosting that is spreadable but holds its shape. Taste and adjust the lemon juice if needed. You can also add a pinch more salt if you like, to balance the sweetness.
Assemble and Frost: Once the cakes are completely cool, you can assemble your masterpiece. Place one cake layer on your serving plate. Generously spread a layer of the lemon buttercream over the top. Carefully place the second cake layer on top. Then, frost the top and sides of the entire cake with the remaining buttercream. You can create pretty swirls or keep it simple and smooth. For an extra touch, you could even garnish with a few fresh blueberries or some finely grated lemon zest. Slice and enjoy this wonderfully moist and flavorful cake!

Frequently Asked Questions:
Q: Can I make this cake ahead of time?
A: Absolutely! The cake itself can be baked a day in advance and stored at room temperature, wrapped tightly. The lemon buttercream is best made closer to serving time for optimal freshness and texture, but can also be made a few hours ahead and stored in the refrigerator. Just be sure to let it soften slightly and re-whip it before frosting the cake.
Q: My zucchini seems to release a lot of water. How do I prevent a soggy cake?
A: This is a common concern! The key is to properly prepare your zucchini. Grate it and then place it in a fine-mesh sieve over a bowl. Let it sit for about 10-15 minutes, pressing down gently occasionally to encourage excess moisture to drain. You can then pat it dry with paper towels for good measure. This step significantly reduces the amount of liquid that goes into your batter.
