Making the Cake Batter
Creating the Zesty Lemon Buttercream
- While the cake is cooling, prepare the luscious lemon buttercream. In a large mixing bowl, beat the 3/4 cup (1 1/2 sticks) unsalted butter (at room temperature, which is essential for a smooth frosting) with an electric mixer until it is light and fluffy. This can take several minutes.
- Gradually add the 4 cups confectioners’ sugar, one cup at a time, beating well after each addition. Once all the confectioners’ sugar is incorporated, the mixture will be thick.
- Now it’s time for that bright, refreshing lemon flavor! Add fresh lemon juice a tablespoon at a time, beating well after each addition, until the buttercream reaches your desired consistency and flavor. You’ll want it to be spreadable but not too thin. The amount of lemon juice needed can vary depending on its acidity and your personal preference. Start with a tablespoon and add more as needed. You can also add a touch of lemon zest for an even more intense citrus punch.

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. This helps prevent them from sinking to the bottom of the cake and also reduces excess moisture.
What are some variations I can try for this Blueberry Zucchini Cake?
You can easily adapt this recipe. Consider adding a teaspoon of cinnamon or nutmeg to the dry ingredients for a warmer spice note. For an extra citrusy punch, add a tablespoon of lemon zest directly into the cake batter. You could also swap out the blueberries for raspberries or a mix of berries.
How should I store leftover cake?
Store any leftover Blueberry Zucchini Cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4-5 days. The lemon buttercream is dairy-based, so refrigeration is recommended for longer storage, especially in warmer climates.
