Ingredients:

3 large eggs

1 cup vegetable oil

1 Tbsp vanilla extract

2 1/4 cups sugar

2 cups shredded zucchini (from about 2 medium zucchinis), squeezed dry

3 cups all purpose flour

1 tsp salt

1 tsp baking powder

1/4 tsp baking soda

1 pint blueberries, tossed in 1 tsp flour

3/4 cup (1 1/2 sticks) unsalted butter, softened to room temperature

4 cups confectioners’ sugar

Fresh lemon juice (about 2-4 Tbsp, to taste)

Cake Preparation

Let’s get started on this wonderfully moist cake! The key to a truly tender zucchini cake is to ensure your zucchini is well-drained. After shredding, place it in a fine-mesh sieve and gently press out as much excess moisture as possible. This prevents the cake from becoming too wet. Similarly, make sure your butter for the buttercream is truly at room temperature; it should yield easily to the touch but not be melted.

1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or one 9×13 inch baking pan. You can also line the bottoms with parchment paper for extra insurance against sticking. In a large bowl, whisk together the wet ingredients: the 3 large eggs, 1 cup of vegetable oil, and 1 tablespoon of vanilla extract. Ensure these are thoroughly combined before moving on.

2. To the wet ingredients, add the 2 1/4 cups of sugar and whisk until smooth. Then, gradually incorporate the 2 cups of squeezed and shredded zucchini. Mix well until it’s evenly distributed throughout the batter. This is where the magic happens for moisture and tenderness, so don’t skip squeezing out that liquid!

3. In a separate medium bowl, whisk together the dry ingredients: 3 cups of all-purpose flour, 1 teaspoon of salt, 1 teaspoon of baking powder, and 1/4 teaspoon of baking soda. These leavening agents will work together to give your cake a lovely lift. Gradually add these dry ingredients to the wet ingredients, mixing on low speed or by hand until just combined. Be careful not to overmix the batter at this stage, as it can lead to a tough cake. A few small lumps are perfectly fine.

4. Now it’s time for the blueberries! Gently fold in the 1 pint of blueberries, which you’ve already tossed in 1 teaspoon of flour. This flour coating helps prevent the berries from sinking to the bottom of the cake during baking. Once the blueberries are evenly distributed, carefully pour the batter into your prepared cake pans. If using round pans, divide the batter evenly between the two. If using a 9×13 inch pan, spread it out evenly.

5. Bake for 30-40 minutes for round pans, or 40-50 minutes for a 9×13 inch pan, or until a wooden skewer or toothpick inserted into the center comes out clean. The baking time will vary depending on your oven and the size of your pans. While the cake is baking, you can start preparing the delicious lemon buttercream. Once baked, allow the cakes to cool in their pans for about 10-15 minutes before inverting them onto a wire rack to cool completely. Ensure the cakes are entirely cool before frosting, otherwise, the buttercream will melt.

Lemon Buttercream Frosting

This buttercream is the perfect tangy complement to the sweet and moist cake. The fresh lemon juice adds a bright, zesty finish that truly elevates the entire dessert.

1. In a large bowl, beat the 3/4 cup (1 1/2 sticks) of softened unsalted butter with an electric mixer until it is light and fluffy. This usually takes about 3-5 minutes. Make sure your butter is truly softened, not melted, for the best consistency.

2. Gradually add the 4 cups of confectioners’ sugar, one cup at a time, mixing on low speed until each addition is incorporated. Scrape down the sides of the bowl as needed. Once all the sugar is incorporated, the mixture will be quite thick.

3. Now, it’s time for the lemon flavor. Add 2 tablespoons of fresh lemon juice to the buttercream. Beat again until smooth and creamy. If the buttercream is too thick, add more lemon juice, a teaspoon at a time, until you reach your desired consistency. If it’s too thin, add a bit more confectioners’ sugar. Taste and adjust the lemon flavor to your preference. You want a good balance of sweetness and tartness.

Once the cake layers have cooled completely, you can assemble and frost your masterpiece. Spread a generous layer of the lemon buttercream between the layers, and then frost the top and sides of the cake. For an extra touch, you can garnish with a few fresh blueberries or a sprinkle of lemon zest. Enjoy every delicious bite!

Frequently Asked Questions:

Can I use frozen blueberries?

Absolutely! If using frozen blueberries, I recommend gently tossing them with a tablespoon of the flour from the recipe before folding them into the batter. This helps prevent them from sinking to the bottom of the cake.

How long will the cake last?

The cake will stay fresh at room temperature, well-covered, for about 2-3 days. For longer storage, it can be refrigerated for up to a week. The lemon buttercream is quite stable.

What can I do if I don’t have zucchini?

While zucchini is key for moisture and tenderness in this recipe, if you are absolutely unable to find it, you could try substituting it with grated apple (about 1.5 cups, unsweetened) or even shredded carrots. However, the texture and flavor will be slightly different.
