Ingredients:

3 large eggs

1 cup vegetable oil

1 Tbsp vanilla extract

2 1/4 cups sugar

2 cups shredded zucchini (about 2 medium zucchini, squeezed to remove excess moisture)

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

Cake Preparation

1. Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or two 8 or 9-inch round cake pans. If using round pans, you might want to line the bottoms with parchment paper as well for easier removal. This ensures your beautiful cake doesn’t stick.

2. In a large bowl, whisk together the wet ingredients: the 3 large eggs, 1 cup of vegetable oil, and 1 tablespoon of vanilla extract. Whisk until everything is well combined and the mixture is a uniform color. This forms the base of our moist cake.

3. Add the 2 1/4 cups of sugar to the wet ingredients and whisk until smooth. Next, incorporate the 2 cups of shredded zucchini. Remember to squeeze out as much excess moisture as possible from your shredded zucchini before adding it. You can do this by placing the shredded zucchini in a clean kitchen towel or cheesecloth and wringin extractg it out firmly. This step is crucial for preventing a soggy cake and ensuring a perfectly tender crum extractb.

4. 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. Give these a good whisk to ensure the leavening agents and salt are evenly distributed throughout the flour. This is important for consistent rise and flavor.

5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed (or by hand with a spatula) until just combined. Be careful not to overmix at this stage, as overmixing can develop the gluten in the flour too much, leading to a tougher cake. A few streaks of flour are perfectly fine; they will disappear as you fold in the blueberries.

6. Gently fold in the 1 pint of blueberries, which you’ve already tossed with 1 teaspoon of flour. This little bit of flour helps to prevent the blueberries from sinking to the bottom of the cake during baking. Fold them in just enough to distribute them evenly throughout the batter.

7. Pour the batter into your prepared baking pan(s) and spread it evenly. 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 can vary depending on your oven, so it’s always best to start checking a little earlier than the suggested time.

8. Once baked, let the cake cool in the pan for about 10-15 minutes before inverting it onto a wire rack to cool completely. Ensure the cake is fully cooled before frosting; a warm cake will melt the buttercream into a gooey mess.

Lemon Buttercream Frosting

While your cake is cooling, let’s whip up this bright and zesty buttercream.

1. In a large bowl, beat the 3/4 cup (1 1/2 sticks) of unsalted butter at room temperature until it’s creamy and smooth. Using room temperature butter is key for a smooth and lump-free buttercream.

2. Gradually add the 4 cups of confectioners’ sugar, about a cup at a time, beating well after each addition. Start on a low speed to avoid a powdered sugar cloud explosion, then increase the speed to medium.

3. Add fresh lemon juice, a tablespoon at a time, beating after each addition, until the frosting reaches your desired consistency and flavor. You’re looking for a fluffy, spreadable frosting. You might need a bit more or less lemon juice depending on how tart you like it and the moisture content of your confectioners’ sugar. Taste and adjust as needed. If the frosting is too thick, add a tiny bit more lemon juice or a splash of milk. If it’s too thin, add a little more confectioners’ sugar.

Once the cake is completely cool, frost it generously with the lemon buttercream. Slice and enjoy this delightful combination of moist cake and tangy frosting!
