❓ Frequently Asked Questions

Can I use frozen zucchini?

Yes, but thaw completely and squeeze out all the liquid before adding.

Do I have to peel the zucchini?

No need! The peel softens as it bakes and adds fiber and color.

Can I double the recipe?

Absolutely—use a 9×13-inch pan and bake for 30–35 minutes.

Are these bars suitable for kids?

Yes! They’re soft, not overly sweet, and loaded with hidden veggies. For picky eaters, you can add chocolate chips to make them more appealing.

Can I add a glaze or frosting?

Yes. A light lemon glaze or dairy-free cream cheese frosting works beautifully, but the bars are also great as-is.
