These zucchini muffins with walnuts are an excellent source of protein, since each muffin contains approximately 7 g protein.
This makes them a great option for anyone looking to increase their protein intake, especially for breakfast or as a post-workout snack.
Health Benefits of Zucchini
Zucchini is a low-calorie vegetable rich in antioxidants and nutrients such as vitamin C, potassium, and fiber. Each muffin even has 7.8 g fiber.
Zucchini is also a good source of antioxidants, which help protect the body against free radicals that can damage cells.
So, adding zucchini to these protein walnut muffins not only adds moisture and texture but also provides a number of health benefits.

Wholesome Ingredients in Healthy Protein Zucchini Muffins, Including Substitutions If You’re on a Vegan or Gluten Free Diet
You’ll need the following healthy ingredients to make Protein Zucchini Muffins – all of which are easy to find at your local grocery store:
- ZUCCHINI – are bursting with potassium, vitamin C, vitamin B6 and fiber, so grab your grater and grate some. There’s no need to peel the skin or drain it. In fact, zucchini contains a lot of water and adds to the muffins’ moisture.
- ALMOND FLOUR – a grain free nut flour that brings loads of nutrients and protein to this healthy muffin recipe. By the way, there’s twice as much almond flour in the recipe than all-purpose flour.
- ALL-PURPOSE FLOUR or GLUTEN FREE ALL-PURPOSE FLOUR – The all-purpose flour acts as a binder.
- GRANULATED SWEETENER OF CHOICE – White or golden brown sugar or your preferred sweetener. The recipe is relatively low in sugar, but but if you’re looking to reduce calories, consider a sugar-free option like monk fruit. Monk fruit sweetener is a great alternative that doesn’t spike blood sugar levels.
- BAKING POWDER – adds some rise to this veggie muffin.
- BAKING SODA – also adds some rise to these Protein Zucchini Muffins.
- CINNAMON – tastes great in these muffins.
- GINGER – is also tasty in this dessert.
- NUTMEG – rounds off the spices.
- SALT – just a pinch.
- ROOM TEMPERATURE EGGS OR VEGAN EGGS – You can make this zucchini muffin recipe with large eggs, flax seed eggs, or a vegan egg replacer.
- OIL – a neutral oil such as avocado oil, canola oil or vegetable oil. I haven’t tried making this with light-tasting olive oil or coconut oil.
- VANILLA EXTRACT – for flavor, aroma and to enhance the other flavors.
- DAIRY OR NONDAIRY MILK OF CHOICE – I use unsweetened almond milk which has barely any calories.
- WALNUTS (OPTIONAL) – taste great in these nutritious zucchini bread muffins. They also add extra protein and a fabulous crunch to every bite.

How to Make Perfectly Moist and Tasty Protein Zucchini Muffins from Simple Ingredients
1. For best results, don’t peel the zucchini. Simply cut off the stem and grate it with a box grater or hand grater.
2. Preheat the oven to 400°F (204°C) and spray a nonstick muffin pan with baking spray or line it with muffin liners.
NOTE: I made these muffins in a jumbo, 6-muffin tin. Feel free to use a regular-size muffin tin but note that the recipe makes 6 cups of muffin batter.

3. In a large bowl, mix together the dry ingredients.
4. Then, add the wet ingredients and mix well.
5. Next, stir in the shredded zucchini and walnuts.

6. Spoon batter into muffin pan – I fill mine to the top. Almond flour is a heavier flour so these muffins will pop up but not overflow when baked.
7. Bake for 20–25 minutes or until a toothpick comes out clean when inserted into one of the muffins.
NOTE: The cooking time applies to jumbo muffins. If you make them in a regular muffin pan, the muffins will need about 15 minutes to bake.
8. Let the Protein Zucchini Muffins cool for about 10 minutes before cooling them further on a wire rack!

Equipment Needed to Make Protein Walnut Muffins
- 1 box grater, hand grater, or food processor – to grate the zucchini.
- 1 mixing spoon or electric mixer – You can mix the batter by spoon or electric mixer.
- 1 large mixing bowl
- 1 six-cup jumbo muffin pan – You can also use a regular 12-cup cupcake pan but note that the recipe makes 6 cups of batter. Another option would be to bake the batter in a 6-cup loaf pan which would give you tasty protein zucchini bread.
- Muffin liners, cupcake liners or baking spray – I don’t use muffin liners. Instead, I spray my nonstick muffin pan with baking spray and the muffins release easily.
