Ingredients:

3 large eggs

1 cup vegetable oil

1 Tbsp vanilla extract

2 1/4 cups sugar

2 cups shredded zucchini

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

Instructions:

Preparing the Cake Batter

1.

Preheat 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 for ensuring your cake doesn’t stick and releases cleanly after baking. If you’re using round pans and plan to stack them for a layer cake, you might also want to line the bottoms with parchment paper for extra insurance.

2.

In a large mixing bowl, whisk together the 3 large eggs, 1 cup vegetable oil, and 1 Tbsp vanilla extract. Make sure these wet ingredients are thoroughly combined. The vegetable oil is key to the cake’s signature moistness, ensuring it stays tender for days. The vanilla extract provides a warm, comforting aroma and flavor base that complements both the zucchini and blueberries beautifully.

3.

Gradually add the 2 1/4 cups sugar to the wet ingredients, whisking until well incorporated. Don’t be tempted to reduce the sugar; it plays a role in the cake’s texture and moisture retention. Once the sugar is blended in, it’s time to incorporate the star vegetable. Stir in the 2 cups shredded zucchini. You want to grate the zucchini finely; this ensures it melds seamlessly into the batter and doesn’t create large, watery chunks. Squeeze out any excess moisture from the zucchini before adding it if you’re concerned about too much liquid, though for this recipe, the oil helps manage moisture well.

4.

In a separate medium bowl, whisk together the 3 cups all purpose flour, 1 tsp salt, 1 tsp baking powder, and 1/4 tsp baking soda. Combining the dry ingredients separately ensures they are evenly distributed, preventing pockets of leavening agents or salt in your finished cake. The baking powder provides lift, while the baking soda reacts with acidic components (even subtle ones in the zucchini or lemon) to give the cake a tender crum extractb and a slight rise.

5.

Add the dry ingredients to the wet ingredients in three alternating additions, begin extractning and ending with the dry ingredients. Mix until just combined after each addition. Be careful not to overmix the batter at this stage. Overmixing can develop the gluten in the flour, leading to a tougher cake. A few streaks of flour remaining are perfectly fine; they will disappear during baking.

6.

Gently fold in the 1 pint blueberries, tossed in 1 tsp flour. Tossing the blueberries in a little flour before adding them to the batter helps prevent them from sinking to the bottom of the cake during baking. This ensures you get lovely bursts of blueberry flavor distributed throughout every slice. Once the blueberries are evenly distributed, pour the batter into your prepared baking pan(s).

7.

Bake for 30-40 minutes for round pans, or 40-50 minutes for a 9×13 pan, or until a toothpick inserted into the center of the cake comes out clean. The baking time will vary depending on your oven and the size of your pans. Let the cake cool in the pan for about 10-15 minutes before inverting it onto a wire rack to cool completely. It’s essential that the cake is entirely cool before frosting, otherwise, the buttercream will melt.

Making the Lemon Buttercream

1.

While the cake is cooling, prepare the Lemon Buttercream. In a large bowl, beat the 3/4 cup (1 1/2 sticks) unsalted butter at room temperature with an electric mixer until light and fluffy. Using room temperature butter is crucial for a smooth, creamy buttercream. If your butter is too cold, it won’t cream properly; if it’s too warm, the frosting can become greasy.

2.

Gradually add the 4 cups confectioners’ sugar to the butter, about a cup at a time, beating on low speed until incorporated. Scrape down the sides of the bowl as needed. This slow addition prevents a cloud of powdered sugar from exploding in your kitchen. Once all the sugar is added, increase the mixer speed to medium-high and beat for another 2-3 minutes until the frosting is smooth and well combined.

3.

Add fresh lemon juice, a tablespoon at a time, beating until the buttercream reaches your desired consistency and flavor. Start with a tablespoon and taste. You’re looking for a frosting that is spreadable but holds its shape, with a bright, zesty lemon flavor that complements the sweet cake. You might need more or less lemon juice depending on the moisture content of your confectioners’ sugar and your personal preference for tangin extractess. Beat for an additional minute or two after adding the lemon juice to ensure everything is thoroughly incorporated.

Assembly

1.

Once the cake has cooled completely, frost it generously with the Lemon Buttercream. If you made a layer cake, place one layer on your serving plate, spread a good amount of frosting on top, then place the second layer. Frost the top and sides of the cake. You can create swirls and peaks with your spatula for a beautiful presentation. If you made a sheet cake, simply spread the buttercream evenly over the top. For an extra touch, you can garnish with a few fresh blueberries or a sprinkle of lemon zest.

Enjoy this incredibly moist and flavorful Blueberry Zucchini Cake! It’s a testament to the magic that can happen when simple, wholesome ingredients come together.

Frequently Asked Questions:

Can I use frozen blueberries instead of fresh?

Absolutely! If you’re using frozen blueberries, toss them with a tablespoon of flour before adding them to the batter to help prevent them from sinking to the bottom. You might also need to bake the cake for a few extra minutes.

How should I store leftover cake?

This cake is best stored in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. The buttercream might firm up in the fridge, so let it come to room temperature for about 30 minutes before serving for the best texture.

Is it possible to make this cake dairy-free?

While adapting the cake itself to be dairy-free is manageable by using plant-based milk and oil, the lemon buttercream relies heavily on butter. For a dairy-free frosting, you would need to find a specific recipe for a vegan lemon buttercream using plant-based butter alternatives and a suitable liquid like lemon juice or a non-dairy milk.
