Ingredients:

3 large eggs

1 cup vegetable oil

1 Tbsp vanilla extract

2 1/4 cups sugar

2 cups shredded zucchini (about 2 medium zucchinis)

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 at room temperature

4 cups confectioners’ sugar

Fresh lemon juice (to taste)

Cake Instructions:

1. Preparing the Wet Ingredients and Zucchini:

Start by preheating your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or one 9×13 inch pan, depending on your preference. This step is crucial for ensuring your cake releases cleanly after baking. In a large bowl, whisk together the 3 large eggs, 1 cup of vegetable oil, and 1 Tbsp of vanilla extract until well combined. Add the 2 1/4 cups of sugar to this wet mixture and whisk until it’s smooth and slightly lighter in color. Now, for the star ingredient: the zucchini. You’ll want to shred your zucchini using the large holes of a box grater. There’s no need to peel it; the skin adds extra nutrients and a lovely subtle color. You should have about 2 cups of shredded zucchini. Gently squeeze out any excess moisture from the shredded zucchini by pressing it between your hands or wrapping it in a clean kitchen towel. This might seem like an extra step, but it helps prevent the cake from becoming too soggy. Add the prepared shredded zucchini to your wet ingredients and stir to incorporate.

2. Combining the Dry Ingredients and Mixing the Batter:

In a separate medium bowl, whisk together the 3 cups of all purpose flour, 1 tsp salt, 1 tsp baking powder, and 1/4 tsp baking soda. Whisking the dry ingredients together ensures that the leavening agents (baking powder and baking soda) and salt are evenly distributed throughout the flour, leading to a consistent rise and flavor in your cake. Now, gradually add the dry ingredients to the wet ingredients, mixing on low speed (if using a mixer) or with a spatula until just combined. Be careful not to overmix the batter at this stage. Overmixing can develop the gluten in the flour too much, resulting in a tougher cake. A few streaks of flour are perfectly fine; they will disappear as you incorporate the blueberries.

3. Adding the Blueberries and Baking:

For the blueberries, it’s important to toss them with 1 tsp of flour before adding them to the batter. This simple step helps prevent the berries from sinking to the bottom of the cake during baking. Gently fold the floured blueberries into the batter until they are evenly distributed. Pour the batter evenly into your prepared cake pans. If you are using round pans, smooth the tops with your spatula. If you are using a 9×13 inch pan, ensure the batter is spread to the edges. Place the pans in the preheated oven. Bake for 30-35 minutes for round pans, or 35-40 minutes for a 9×13 inch pan, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The aroma of warm blueberries and zucchini filling your kitchen is simply divine!

4. Cooling the Cakes:

Once baked, remove the cakes from the oven and let them cool in their pans on a wire rack for about 15-20 minutes. This initial cooling period allows the cakes to firm up slightly, making them easier to handle. After this, carefully invert the cakes onto the wire rack to cool completely. If you’re frosting the cake, it’s essential that the cakes are entirely cool. Frosting a warm cake will cause the buttercream to melt and slide off, creating a messy and unappealing finish. Patience here is key for a beautiful final presentation.

5. 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. This usually takes about 2-3 minutes. Gradually add the 4 cups of confectioners’ sugar, about a cup at a time, beating well after each addition. The mixture will become quite thick. Now, it’s time to add the fresh lemon juice. Start by adding 1-2 tablespoons of fresh lemon juice and beat until combined. Continue to add lemon juice, a tablespoon at a time, beating after each addition, until you reach your desired consistency and lemon flavor. You want a frosting that is spreadable but not too runny. The tartness of the lemon juice beautifully complements the sweetness of the cake and cuts through its richness. Taste and adjust the lemon juice and confectioners’ sugar as needed.

6. Assembling and Decorating:

Once the cakes are completely cool, you can assemble your masterpiece. If you baked two round cakes, place one layer on your serving plate or cake stand. Spread a generous layer of the lemon buttercream over the top of the first cake. Carefully place the second cake layer on top. Apply a thin “crum extractb coat” of frosting all over the cake, which is a very thin layer that traps any loose crum extractbs. Chill the cake in the refrigerator for about 15-20 minutes to set the crum extractb coat. Then, apply the remaining buttercream generously over the top and sides of the cake, smoothing it with an offset spatula or creating decorative swirls. For a final touch, you can garnish with fresh blueberries or a sprinkle of lemon zest. Slice, serve, and enjoy this wonderfully moist and flavorful cake!

Frequently Asked Questions:

Can I make this cake ahead of time?

Yes! The cake itself can be baked up to two days in advance and stored, well-wrapped, at room temperature. The lemon buttercream is best made the day you plan to frost the cake for optimal freshness and texture. You can also bake and cool the cake layers and freeze them, then frost once thawed.

What if I don’t have fresh blueberries?

Frozen blueberries work wonderfully in this recipe! You might want to toss them in a tablespoon of flour before adding them to the batter to help prevent them from sinking to the bottom. Just be sure they are completely thawed and drained of excess moisture before adding them.
