Ingredients
Dry Ingredients
1 ½ cups rolled oats (blended into oat flour or left whole for texture)
½ cup unsweetened cocoa powder
1 teaspoon baking powder
½ teaspoon baking soda
½ teaspoon ground cinnamon
¼ teaspoon salt
1–2 teaspoons espresso powder (optional, enhances chocolate flavor)
Wet Ingredients
1 ½ cups finely shredded zucchini (excess moisture squeezed out)
2 ripe bananas, mashed
2 large eggs
¼ cup maple syrup, honey, or coconut sugar
¼ cup avocado oil, coconut oil, or olive oil
1 teaspoon vanilla extract
Mix-Ins
½ cup dark or semi-sweet chocolate chips (plus extra for topping)
Optional: chopped walnuts, almonds, or pecans
Optional: shredded coconut for added texture
Instructions
Prepare the Oven and Pan
Preheat oven to 350°F (175°C).
Line a 12-cup muffin tray with paper liners or lightly grease each cup.
Blend or Prepare Oats
Blend rolled oats into a fine flour using a food processor or blender if you prefer a smoother muffin texture. Alternatively, keep them whole for a more rustic bite.
Mix Dry Ingredients
In a large bowl, combine oat flour (or rolled oats), cocoa powder, baking powder, baking soda, cinnamon, salt, and espresso powder if using.
Whisk until evenly mixed and lump-free.
Combine Wet Ingredients
In a separate bowl, mash the bananas until smooth.
Add eggs, maple syrup, oil, and vanilla extract. Whisk until fully combined.
Fold in the shredded zucchini.
Make the Batter
Pour the wet ingredients into the dry mixture.
Stir gently until just combined. Do not overmix to keep muffins soft and fluffy.
Fold in chocolate chips and optional nuts.
Fill and Bake
Divide batter evenly into muffin cups, filling each about ¾ full.
Top with extra chocolate chips if desired.
Bake for 20–25 minutes or until a toothpick inserted in the center comes out mostly clean.
Cool and Serve
Allow muffins to cool in the pan for 5–10 minutes.
Transfer to a wire rack to cool completely before serving.
Tips
Squeeze the Zucchini Well
Removing excess moisture is important. Too much water can make muffins dense and soggy.
Use Very Ripe Bananas
The darker the banana, the sweeter and more flavorful your muffins will be.
Don’t Overmix the Batter
Overmixing can make muffins tough instead of soft and tender.
Blend Oats for Smooth Texture
Oat flour gives a bakery-style muffin texture, while whole oats create a chewier bite.
Check Doneness Properly
Because of zucchini moisture, always test with a toothpick rather than relying only on time.
Add Chocolate Last
Fold in chocolate chips at the end to avoid breaking them down during mixing.
Let Muffins Cool Fully
They firm up as they cool, improving texture and flavor.
Adjust Sweetness Naturally
If your bananas are very ripe, you can reduce added sweetener slightly.
Use Paper Liners
They help prevent sticking and keep muffins moist.
Store Properly
Keep in an airtight container to maintain softness for several days.
