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 (about 2-4 Tbsp, or to taste)

Instructions:

Preparing the Cake Batter

Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease and flour two 9-inch round cake pans. You can also line the bottoms with parchment paper for extra insurance against sticking. In a large bowl, whisk together the 3 large eggs, 1 cup vegetable oil, and 1 Tbsp vanilla extract until well combined. This wet ingredient base is crucial for a tender cake. The oil, in particular, contributes to incredible moisture that oil-based cakes are famous for.

Gradually add the 2 1/4 cups sugar to the wet ingredients, whisking until smooth and no longer gritty. Next, stir in the 2 cups shredded zucchini. Don’t worry if it looks a bit wet; the zucchini will release moisture during baking, contributing to the cake’s moist texture. Gently fold in the shredded zucchini, ensuring it’s evenly distributed throughout the batter.

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. Whisking the dry ingredients together helps to aerate them and ensures that the leavening agents are evenly distributed, leading to a consistent rise. Add these dry ingredients to the wet ingredients in two additions, mixing until just combined. Be careful not to overmix the batter at this stage, as overmixing can develop the gluten in the flour, resulting in a tougher cake. A few small lumps are perfectly fine.

Now for the star of the show: the blueberries! Gently fold in the 1 pint blueberries that you’ve tossed with 1 tsp of flour. Tossing the blueberries in a little flour before adding them to the batter helps to prevent them from sinking to the bottom of the cake during baking. Once incorporated, divide the batter evenly between the prepared cake pans. Smooth the tops with a spatula.

Baking and Cooling the Cake Layers

Bake for 30-40 minutes, or until a wooden skewer or toothpick inserted into the center of the cakes comes out clean. The exact baking time will vary depending on your oven, so it’s always best to check for doneness. Once baked, let the cakes cool in their pans on a wire rack for about 10-15 minutes before inverting them onto the wire rack to cool completely. Ensuring the cakes are fully cooled before frosting is essential; otherwise, the buttercream will melt and slide right off.

Whipping Up the Lemon Buttercream

While the cakes are cooling, prepare the lemon buttercream. In a large bowl, using an electric mixer (a stand mixer with a paddle attachment is ideal, but a hand mixer works just as well), beat the 3/4 cup (1 1/2 sticks) unsalted butter until it’s light and fluffy, about 2-3 minutes. Make sure your butter is truly at room temperature; it should yield slightly when pressed but not be melted.

Gradually add the 4 cups confectioners’ sugar, about 1 cup at a time, beating well after each addition. The mixture will become thick. Once all the confectioners’ sugar is incorporated, add about 2 tablespoons of fresh lemon juice. 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, you can add a little more confectioners’ sugar. Taste the buttercream and adjust the lemon juice to your preference for tangin extractess.

Assembling and Decorating Your Masterpiece

Once the cake layers are completely cool, you can begin extract assembling. Place one cake layer on your serving plate or cake stand. Generously spread about a third of the lemon buttercream over the top. Carefully place the second cake layer on top.

Frost the top and sides of the entire cake with the remaining lemon buttercream. You can create a smooth finish with an offset spatula, or add some rustic swirls for a more casual look. If you have any extra blueberries, you can scatter a few on top for decoration. Chill the cake for about 15-30 minutes before slicing and serving to allow the buttercream to set slightly.

Enjoy this wonderfully moist and flavorful cake! It’s a fantastic way to enjoy the bounty of summer produce in a truly delicious way.
