Grate your zucchini and squeeze it in a clean kitchen towel or cheesecloth to remove excess moisture, preventing soggy muffins and ensuring the perfect tender crumb texture.

Use a kitchen scale or lightly oil your measuring cup before adding agave nectar to prevent sticking, and measure it accurately since it's sweeter than sugar—less is needed for optimal sweetness.

Whisk together the baking powder, baking soda, and spices before folding into wet ingredients to ensure even distribution and consistent rise throughout all muffins.

Fill muffin cups only two-thirds full and place a muffin cup filled with water in the empty slot to promote even baking and prevent the outer muffins from browning too quickly.

Let muffins rest in the pan for 5 minutes after baking before transferring to a cooling rack; this prevents them from breaking apart while still maintaining that desirable moist interior.
