Ingredients

Wet Ingredients

  • 1 cup mashed very ripe bananas
  • 1 cup grated zucchini (measured before squeezing moisture out)
  • ¼ cup avocado oil or olive oil
  • 2 large eggs
  • 2 teaspoons pure vanilla extract
  • ⅓ cup honey or maple syrup
  • ¼ cup milk of choice

Dry Ingredients

  • 1 ¼ cups whole wheat flour (or sub cup-for-cup gluten free flour blend)
  • ½ cup rolled oats
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon sea salt
  • 1½ teaspoons ground cinnamon

Add-ins

  • ¼ cup chopped walnuts (optional)
  • ¼ cup chocolate chips

Instructions

  1. Preheat and Prepare Muffin Tin: Preheat your oven to 350℉ (175℃). Line a muffin tin with liners or grease the cups lightly with oil to prevent sticking.
  2. Drain Zucchini: Take the grated zucchini and place it in the center of a clean dish towel or large paper towel. Wrap it up tightly and squeeze out as much moisture as possible. This ensures your muffins won’t become soggy. Set the drained zucchini aside.
  3. Mash Bananas and Mix Wet Ingredients: In a medium bowl, mash the very ripe bananas until smooth. Add the avocado or olive oil, eggs, vanilla extract, honey or maple syrup, and milk. Whisk or mix these together until thoroughly combined.
  4. Add Dry Ingredients: To the wet mixture, add whole wheat flour, rolled oats, baking powder, baking soda, sea salt, and ground cinnamon. Carefully mix until just combined; avoid over mixing to maintain muffin fluffiness.
  5. Incorporate Zucchini and Add-ins: Fold in the drained zucchini, chopped walnuts, and chocolate chips gently, being careful not to overwork the batter.
  6. Portion Batter and Add Toppings: Spoon the batter evenly into the prepared muffin tin cups. Optionally, top each muffin with extra walnuts and chocolate chips for added texture and visual appeal.
  7. Bake: Place the muffin tin in the oven and bake for 22-24 minutes. The muffins should be golden on top, and a toothpick inserted in the center should come out clean. Alternatively, use a kitchen thermometer and bake until the internal temperature reaches 200℉ to ensure perfect doneness without dryness.
  8. Cool: Remove the muffins from the oven and allow them to cool in the pan for 15 minutes to set before removing. Once cool, enjoy immediately or store as desired.
  9. Storage: Store muffins in an airtight container in the refrigerator for up to 4-5 days or freeze for up to a month to maintain freshness.

Notes

  • Do not over mix the batter; this is key to maintaining fluffy muffins.
  • Make sure to squeeze out the zucchini moisture well to prevent soggy muffins.
  • Swap whole wheat flour with a gluten-free flour blend for a gluten-free version.
  • Walnuts and chocolate chips are optional but add great flavor and texture.
  • Muffins can be stored refrigerated for 4-5 days or frozen for up to one month.
  • For perfectly baked muffins, a kitchen thermometer can help – aim for 200℉ in the center.
  • Original recipe variations include slightly different ingredient ratios and baking times but follow similar techniques.
