Step 5: Bake

❓ Frequently Asked Questions

Can I taste the zucchini?

No. The zucchini adds moisture and tenderness but has a very mild flavor that is masked by the lemon.

Can I use coconut flour instead of almond flour?

Not directly. Coconut flour absorbs much more liquid, so it requires a different recipe ratio.

Is this cake gluten-free?

Yes. Since it’s made with almond flour instead of wheat flour, it’s naturally gluten-free. Be sure your baking powder is certified gluten-free if needed.

Do I need to peel the zucchini?

No. The peel is tender, nutritious, and blends into the cake during baking.

Can I make this ahead of time?

Yes! In fact, the lemon flavor becomes even more pronounced after the cake rests overnight in the refrigerator, making it an excellent make-ahead dessert.
