Don't skip squeezing that zucchini dry, it's a game-changer. Feel free to swap in different nuts if you want, maybe try pecans too. Keep an eye on your oven and go easy when mixing the batter so it stays soft and fluffy.

Storage Smarts

Your cake will stay tasty on the counter for around 3 days or stick it in the fridge for up to a week. Warming up leftovers brings back that just-baked feel. You can even make the frosting a day ahead and keep it cold until needed.

Frequently Asked Questions

→ How do I handle the zucchini?

Squeeze out extra water from zucchini to avoid ending up with a heavy, wet cake. The drier, the better for baking!

→ Can I swap gluten-free flour?

Sure, you can use regular flour instead. The cake might feel slightly different, but it'll still be delicious.

→ Is pistachio extract a must?

It's not required, but it gives a stronger nutty flavor. Even without it, the cake's still amazing.

→ Can I bake this ahead of time?

Absolutely, just bake the layers up to 48 hours earlier. Keep them tightly wrapped and frost when ready to serve.

→ Why mix two types of sugar?

Brown sugar brings moisture and richness. White sugar keeps the texture right. Together, they create the perfect balance.
