Can I use frozen zucchini for this recipe?

Yes, you can use frozen zucchini, but you must thaw it completely and drain it thoroughly in a sieve before measuring. Frozen zucchini releases significantly more moisture than fresh because the freezing process breaks down the cell walls. If you do not squeeze the thawed zucchini until it is quite dry, the extra water will ruin the structural integrity of the batter.

How should I store the leftover cake?

Because of the cream cheese frosting, this cake must be stored in the refrigerator to prevent spoilage. Cover the pan tightly with aluminum foil or plastic wrap to keep the crumb from drying out in the cold air. The cake will stay fresh and moist for up to 5 days, and many tasters find the flavors actually improve after the first 24 hours of refrigeration.

What is the best way to grate zucchini for baking?

Use the small or medium holes on a box grater to ensure the pieces are small enough to melt into the batter during the bake. Large shreds can create pockets of moisture that lead to an uneven crumb and may be unappealing to some diners. Aim for a consistent shred that looks like fine confetti, which allows for the most even distribution throughout the cake.

Can I replace the oil with applesauce?

You can replace half of the oil with unsweetened applesauce to reduce the fat content, but be aware that it will change the final texture. Oil provides a specific type of moisture and tenderness that applesauce cannot fully replicate, often resulting in a slightly more rubbery crumb. If you make this change, do not over-mix the batter, as the lack of fat makes the gluten much more sensitive to development.

Why did my cake sink in the middle?

A sunken center is usually the result of one of two things: under-baking or too much moisture from the zucchini. If the internal temperature doesn't reach 205°F, the starch structure isn't strong enough to support the weight of the cake as it cools. Always ensure you have pressed the zucchini dry and use an oven thermometer to confirm your oven is actually reaching 350°F.

Can I bake this recipe as muffins instead?

This batter works well for muffins; simply grease a standard muffin tin and fill each cup about three-quarters full. Bake at 350°F for 20 to 25 minutes, or until a tester comes out clean. Because muffins bake faster, you will need to watch them closely to ensure they don't dry out, as the higher surface-area-to-volume ratio makes them more prone to over-baking.

Instructions

Prepare oven and pan. Preheat your oven to 350°F and thoroughly grease a 9×13 baking pan to ensure the cake releases easily.
Combine dry ingredients. In a medium bowl, whisk together the flour, cinnamon, baking soda, baking powder, and salt until uniform.
Aerate egg mixture. Using a stand mixer, beat the eggs on high until frothy, then lower the speed to incorporate the sugar, oil, vanilla, and lemon zest.
Incorporate flour mixture. Gradually stir the dry ingredients into the wet mixture in three stages, being careful not to overmix the batter.
Fold in extras. Gently fold in the pressed, dry zucchini and the chopped walnuts using a silicone spatula until evenly distributed.
Bake the cake. Pour the batter into the prepared pan and bake for 40 to 45 minutes until a tester comes out clean and the center registers 205°F.
Cool and frost. Allow the cake to cool completely on a wire rack before spreading the cream cheese frosting evenly over the top surface.

Notes

Ensure zucchini is thoroughly squeezed in a sieve to prevent a soggy, dense cake center.
Use a digital scale to weigh your flour, as packing it into measuring cups can lead to a dry, crumbly texture.
Toast the walnuts in a 350°F oven for 6-8 minutes before adding them to the batter to unlock deeper flavor and aroma.
Bring your cream cheese and butter to room temperature before mixing the frosting to avoid unwanted lumps.
Check the internal temperature of the cake with a probe thermometer to guarantee the starch has fully set at 205°F.
