Ingredients in healthy Protein Zucchini Muffins, including substitutions if you’re on a vegan or gluten-free diet
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 – Sugar or your preferred sweetener. The recipe is relatively low in sugar, but for fewer calories, opt for a sugar-free sweetener.
BAKING POWDER – adds some rise to this veggie muffin.
BAKING SODA – also adds some rise to this snack.
CINNAMON – tastes great in these muffins.
GINGER – is also tasty in this dessert.
NUTMEG – rounds off the spices.
SALT – just a pinch.
EGGS OR VEGAN EGGS – This zucchini muffin recipe works with either.
OIL – a neutral oil such as avocado oil, canola oil or vegetable oil.
VANILLA EXTRACT – for flavor, aroma and to enhance the other flavors.
MILK OF CHOICE – I use unsweetened almond milk which has barely any calories.
WALNUTS (optional) – taste great in these nutritious zucchini bread muffins, also add a load of protein and a fabulous crunch to every bite.

How to create perfectly moist and tasty zucchini muffins loaded with protein, walnuts and almond flour
1. There’s no need to 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-cup 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 mixing bowl, mix together the dry ingredients.
4. Then, add the wet ingredients and mix well.
5. Next, stir in the 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 them cool for about 10 minutes before serving!

- 1 box grater or hand grater – 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 muffin 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 or baking spray – I don’t use muffin liners. Instead, I spray my nonstick muffin pan with baking spray and the muffins release easily.
