The Secret to Moist Vegan Muffins

Zucchini is one of our favorite baking ingredients because it adds incredible moisture without making baked goods taste like vegetables. Once it’s shredded and folded into the batter, it practically disappears, leaving behind soft, tender muffins that stay fresh for days.

This recipe also uses a simple flax egg, applesauce, and a little oil to create the perfect texture—rich enough to feel indulgent while still being wonderfully light.

Ingredient Notes

Here’s what makes these muffins so good:

Zucchini – Freshly shredded zucchini adds moisture and tenderness. Be sure to squeeze out as much excess water as possible before measuring so your muffins bake up perfectly.
Ground Flaxseed – Mixed with water, flaxseed creates an easy plant-based egg substitute that helps bind everything together.

Unsweetened Applesauce – Adds moisture while replacing some of the oil you’d typically find in muffins. Homemade apple puree will work just as well.
Cocoa Powder – A bit of cocoa powder gives these muffins their deep chocolate flavor.
Chocolate Chips – Because every chocolate muffin deserves pockets of melted chocolate. Mini vegan chocolate chips are our favorite!
