Ingredients:

Cake Instructions:

1. Prepare the Wet Ingredients: Begin extract by preheating your oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease and flour a 9×13 inch baking pan, or two 8-inch round cake pans. In a large bowl, whisk together the 3 large eggs, 1 cup of vegetable oil, and 1 tablespoon of vanilla extract until well combined. This forms the moist foundation of our cake. The oil will contribute significantly to the cake’s tender crum extractb.

2. Combine Dry Ingredients and Add Zucchini: 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. These leavening agents will work together to give our cake a lovely rise. Once the dry ingredients are thoroughly mixed, gradually add the 2 and 1/4 cups of sugar to the wet ingredients, beating until just combined. Now, it’s time to incorporate the star of our show – the 2 cups of shredded zucchini. Gently fold the shredded zucchini into the wet batter until evenly distributed. Don’t be alarmed by the amount of zucchini; it will disappear into the cake, leaving behind only its wonderful moisture.

3. Combine Wet and Dry Mixtures and Add Blueberries: 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, as this can lead to a tough cake. Overmixing develops the gluten in the flour too much. Finally, gently fold in the 1 pint of blueberries that you’ve tossed with 1 teaspoon of flour. Tossing the blueberries in a little flour helps prevent them from sinking to the bottom of the cake during baking. This coating creates a slight barrier, allowing them to distribute more evenly throughout the batter.

4. Bake the Cake: Pour the batter evenly into your prepared baking pan(s). If using round pans, you can bake them one at a time or both if your oven allows for even heating. Bake for 30-35 minutes for round pans, or 40-45 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 exact baking time will depend on your oven. Keep an eye on it towards the end of the baking time. Once baked, allow the cake to cool in the pan for about 10-15 minutes before inverting it onto a wire rack to cool completely. Ensuring the cake is fully cooled before frosting is crucial to prevent the buttercream from melting.

Lemon Buttercream Frosting Instructions:

1. Cream the Butter: While your cake is cooling, prepare the luscious lemon buttercream. Make sure your 3/4 cup (1 and 1/2 sticks) of unsalted butter is at room temperature. This is very important for achieving a smooth and creamy frosting. In a large bowl, beat the softened butter with an electric mixer on medium-high speed until it’s pnon-alcoholic ale and fluffy, which usually takes about 3-5 minutes. This creaming process incorporates air, making the frosting light.

2. Add Confectioners’ Sugar and Lemon Juice: Gradually add the 4 cups of confectioners’ sugar to the creamed butter, about a cup at a time, beating on low speed until just combined after each addition. Once all the confectioners’ sugar is incorporated, increase the mixer speed to medium-high and beat for another 2-3 minutes until the frosting is smooth and creamy. Now, it’s time to add the bright, zesty flavor! Add fresh lemon juice, a tablespoon at a time, beating well after each addition, until you reach your desired consistency and a pleasant lemon flavor. Start with 2-3 tablespoons and add more as needed. The amount of lemon juice will depend on its acidity and your preference. Taste and adjust the sweetness or tartness as desired.

3. Frost the Cooled Cake: Once the cake is completely cool, you can frost it generously with the lemon buttercream. Use an offset spatula to spread the frosting evenly over the top and sides of the cake. For a more decorative finish, you can pipe the frosting using a pastry bag and tip. The vibrant yellow of the lemon buttercream complements the rustic charm of the blueberry zucchini cake beautifully. Enjoy this moist, flavorful cake!

FAQs:

Can I omit the zucchini?

While you can omit the zucchini, it will significantly change the texture of the cake. The zucchini is what lends this Blueberry Zucchini Cake its incredible moisture and tender crum extractb. If you’re not a fan of zucchini in baking, I’d suggest trying a different cake recipe that doesn’t rely on it for moisture.

How should I store this cake?

Store any leftover cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. The buttercream can soften at room temperature, so refrigeration is best for longer storage.

Can I make this cake ahead of time?

Absolutely! The cake layers can be baked a day in advance and stored at room temperature. The buttercream can also be made a day ahead and refrigerated; simply let it come to room temperature and re-whip it before frosting the cooled cake.
