Blueberry Zucchini Cake with Lemon Buttercream

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 and prepare your pans. Begin extract by preheating your oven to 350 degrees Fahrenheit (175 degrees Celsius). This ensures your oven is at the correct temperature when the batter is ready, leading to even baking. Next, grease and flour two 9-inch round cake pans, or a 9×13 inch baking pan. For extra insurance against sticking, you can also line the bottoms of your round pans with parchment paper rounds, then grease and flour the parchment. This step is crucial for ensuring your beautiful cake releases cleanly from the pan.

2. Combine wet ingredients and sugar. In a large mixing bowl, whisk together the 3 large eggs, 1 cup of vegetable oil, and 1 tablespoon of vanilla extract until well combined. This forms the liquid base of your cake. Next, gradually add the 2 1/4 cups of sugar to the wet ingredients, whisking until the mixture is smooth and slightly lighter in color. The sugar will start to dissolve, contributing to the cake’s tender crum extractb and sweetness.

3. Incorporate the shredded zucchini. Add the 2 cups of shredded zucchini to the wet ingredients. You don’t need to squeeze the moisture out of the zucchini; the extra moisture contributes to the cake’s incredible tenderness. Stir everything together until the zucchini is evenly distributed throughout the wet mixture. Don’t worry if it looks a little lumpy at this stage; it will all come together when you add the dry ingredients.

4. Combine and add dry ingredients. In a separate medium bowl, whisk together the 3 cups of all-purpose flour, 1 teaspoon of salt, 1 teaspoon of baking powder, and 1/4 teaspoon of baking soda. Whisking the dry ingredients together ensures that the leavening agents and salt are evenly distributed, preventing pockets of saltiness or uneven rising. Now, gradually add the 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. Overmixing can develop the gluten in the flour too much, resulting in a tougher cake. A few streaks of flour remaining are okay, as they will disappear during baking.

5. Gently fold in the blueberries. Prepare your 1 pint of blueberries by tossing them with 1 teaspoon of flour. This step helps prevent the blueberries from sinking to the bottom of the cake during baking. Gently fold the floured blueberries into the cake batter using a spatula. Be delicate to avoid crushing the berries, which can release their juices and color the batter too much. Distribute them as evenly as possible throughout the batter.

6. Bake the cake. Divide the batter evenly between your prepared cake pans or pour it into the 9×13 inch pan. Smooth the top with a spatula. 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, so it’s always best to start checking for doneness a little early. Once baked, let the cakes 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.

Making the Lemon Buttercream Frosting

1. Cream the butter. While the cake is cooling, prepare your lemon buttercream. In a large mixing bowl, beat the 3/4 cup (1 1/2 sticks) of unsalted butter with an electric mixer until it’s light and fluffy. Ensure your butter is at room temperature for optimal creaming. This process incorporates air, making the frosting smooth and spreadable.

2. Gradually add confectioners’ sugar. With the mixer on low speed, gradually add the 4 cups of confectioners’ sugar, about a cup at a time. Mix until just combined after each addition. 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 creamy.

3. Add lemon juice for flavor and consistency. Add fresh lemon juice, a tablespoon at a time, and continue to beat until you reach your desired consistency and lemon flavor. Start with about 2-3 tablespoons and add more as needed. The lemon juice will brighten the flavor and thin the frosting slightly. You’re looking for a spreadable consistency that isn’t too stiff or too runny.

Assembling and Decorating

Once your cakes are completely cool, you can frost them. If you baked two round cakes, place one cake layer on your serving platter, spread a generous amount of lemon buttercream over the top, then carefully place the second cake layer on top. Frost the top and sides of the entire cake with the remaining buttercream. If you used a 9×13 inch pan, simply frost the top of the cooled cake. You can create swirls with your spatula for a rustic look, or smooth it out for a more polished finish. For an extra touch, you could garnish with a few fresh blueberries or a sprinkle of lemon zest. Enjoy this delightful cake!

Frequently Asked Questions:

Can I freeze this Blueberry Zucchini Cake?

Yes, absolutely! Once completely cooled, you can wrap individual slices or the whole cake tightly in plastic wrap and then foil before freezing. It should stay fresh for up to 2-3 months. Thaw overnight in the refrigerator before serving.

My zucchini seems very watery, will that affect the cake?

It’s best to squeeze out as much excess moisture as possible from your grated zucchini. You can do this by placing the grated zucchini in a clean kitchen towel or cheesecloth and wringin extractg it out over the sink. This step is crucial for ensuring a perfectly textured cake and preventing it from becoming dense or soggy.

What can I use instead of lemon for the buttercream?

If lemon isn’t your favorite, you can easily substitute it with lime zest and juice for a similar tartness. A touch of vanilla extract can also be added for a classic flavor profile if you prefer to omit the citrus altogether.
