Cake Instructions:

Preparing the Cake Batter

First, preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or one 9×13 inch rectangular pan. For extra insurance against sticking, you can also line the bottoms of the round pans with parchment paper circles before greasing and flouring. This step is crucial to ensure your beautiful cake releases cleanly from the pans after baking.

In a large mixing bowl, whisk together the wet ingredients. Crack your 3 large eggs into the bowl, followed by the 1 cup of vegetable oil and the 1 tablespoon of vanilla extract. Whisk these together until they are well combined and slightly frothy. This forms the liquid base of our cake.

Next, gradually add the 2 1/4 cups of sugar to the wet ingredients. Whisk until the sugar is fully incorporated and the mixture is smooth. It’s important to ensure all the sugar is dissolved to prevent a gritty texture in your final cake.

Now it’s time for our star vegetable! Add the 2 cups of shredded zucchini to the bowl. You can shred your zucchini using the large holes of a box grater. Don’t worry about squeezing out all the moisture from the zucchini; that’s what makes this cake so wonderfully moist. Stir the zucchini into the wet ingredients until it’s evenly distributed. The mixture might look a little thick and lumpy at this stage, which is perfectly normal.

In a separate medium bowl, whisk together the dry ingredients. Combine the 3 cups of all-purpose flour, 1 teaspoon of salt, 1 teaspoon of baking powder, and 1/4 teaspoon of baking soda. Whisking the dry ingredients together before adding them to the wet ingredients helps to evenly distribute the leavening agents (baking powder and baking soda), ensuring a consistent rise and texture throughout the cake.

Now, gradually add the dry ingredients to the wet ingredients, mixing on low speed or by hand until just combined. Be careful not to overmix. Overmixing can develop the gluten in the flour too much, resulting in a tough cake. Stop mixing as soon as you no longer see streaks of dry flour.

Gently fold in the 1 pint of blueberries, which you’ve already tossed with 1 teaspoon of flour. This light coating of flour helps prevent the blueberries from sinking to the bottom of the cake during baking. Fold them in carefully to avoid crushing them too much. We want bursts of blueberry, not a uniformly blue batter.

Baking the Cake

Divide the batter evenly between your prepared cake pans. If using two 9-inch round pans, try to get roughly the same amount of batter in each. If using a 9×13 inch pan, pour all the batter into the pan. Smooth the top of the batter with a spatula.

Bake in the preheated oven for 30-40 minutes for round pans, or 40-50 minutes for a rectangular pan. The exact baking time will vary depending on your oven. You’ll know the cake is done when a wooden skewer or toothpick inserted into the center comes out clean, with no wet batter attached. The edges of the cake should also be pulling away slightly from the sides of the pan.

Once baked, let the cakes 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. If you try to remove them too soon, they might break.

Making the Lemon Buttercream Frosting

While the cakes are cooling, prepare the 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 – soft enough to indent easily with your finger, but not melted. This will give you the smoothest, creamiest frosting.

Gradually add the 4 cups of confectioners’ sugar, about a cup at a time, beating well after each addition. The mixture will become very thick.

Once all the confectioners’ sugar is incorporated, add fresh lemon juice, a teaspoon at a time, until the frosting reaches your desired consistency. Start with about 1-2 tablespoons of lemon juice. You’re looking for a spreadable, but not too runny, frosting. The lemon juice adds both flavor and moisture, balancing the sweetness of the confectioners’ sugar. Taste the frosting as you go and adjust the amount of lemon juice to achieve your perfect balance of tart and sweet. If it becomes too thin, you can add a little more confectioners’ sugar.

Assembling and Frosting the Cake

Once the cakes have cooled completely, you can assemble and frost them. If you baked your cake in two round pans, place one layer on your serving plate or cake stand. Generously spread a layer of the lemon buttercream over the top of this first cake layer.

Carefully place the second cake layer on top. If you baked your cake in a rectangular pan, simply frost the top of the cooled cake.

Apply a thin “crum extractb coat” of frosting all over the cake. This is a very light layer of frosting that traps any loose crum extractbs. Chill the cake in the refrigerator for about 20-30 minutes to allow the crum extractb coat to set. This step is optional but highly recommended for a clean, professional-looking finish.

After the crum extractb coat has chilled and set, apply the remaining lemon buttercream generously over the entire cake, including the top and sides. Use an offset spatula to create smooth sides or decorative swirls, as you prefer. You can also use the back of a spoon for a rustic finish. For an extra touch, you could garnish the top with a few fresh blueberries or a sprinkle of lemon zest. Let the frosting set slightly before slicing and serving this delightful Blueberry Zucchini Cake with Lemon Buttercream. Enjoy every moist, flavorful bite!

Don’t be shy about drizzling a little extra lemon juice over the top of the buttercream for an even more intense citrus kick.

Frequently Asked Questions:

Can I freeze this cake?

Absolutely! Once the cake is completely cooled and the buttercream is set, you can wrap it tightly in plastic wrap and then in aluminum foil. It should freeze well for up to 2-3 months. Thaw it overnight in the refrigerator and then bring it to room temperature before serving for the best texture.

My zucchini seemed very watery. Will this affect the cake?

It’s normal for zucchini to release a lot of liquid. That’s actually what contributes to the amazing moistness of this cake! However, if your zucchini is exceptionally watery, you can gently squeeze out some of the excess moisture using a clean kitchen towel or cheesecloth before adding it to the batter. This ensures you don’t make the batter too wet, which could lead to a gummy texture.
