Fresh Zucchini
1:1 Gluten Free (All Purpose) Baking Flour – or a regular all purpose flour
Unflavored Whey-Caesin Protein Powder to replace some of the flour (and carbs) in the recipe for a slightly low calorie zucchini bread. I use Quest Nutrition.
Vanilla Whey-Caesin Protein Powder; This is the source of protein and sweetness in the low sugar zucchini bread since there’s no actual sugar in this recipe. Quest again here.
Non-fat Greek Yogurt to add in moisture and have a no oil recipe
Unsweetened Almond Milk
Applesauce
Eggs
Coconut Oil

Ground Cinnamon
A bit of Ground Nutmeg (Optional)
Baking Powder
Baking Soda
Cinnamon Toast Crunch Cereal

And for the Zucchini Muffins with Cinnamon Crunch Topping

For an extra amazing cinnamon streusel zucchini muffin recipe, I added cinnamon toast crunch cereal. Here’s what you need for zucchini muffins with cinnamon crunch topping:

Cinnamon Toast Crunch Cereal
Softened Butter
1:1 Zero Calorie Sugar Substitute -I use Lakanto Golden here to keep this recipe sugar free; (code HAYLSKITCHEN for a discount here too)
More Flour
More Cinnamon

Protein Powder Note:

I haven’t tried Whey protein, pea protein or other plant based ones, so I can’t say how those would work here.

Be sure to use a protein powder sweetened with stevia or monk fruit if you want a proper low sugar and actually sugar free zucchini muffin.

Tips for the perfect Protein Powder Zucchini Muffins

This high protein zucchini muffin is really easy to make, but baking with protein powder can get tricky; Here’s some tips for the perfect protein powder zucchini muffin!

Grease the muffin pan liners if they aren’t silicon.
This will allow the protein powder muffins to come off easily.

Use melted coconut oil
You want to be able to whisk it completely into the wet ingredients; Microwave to melt if needed.

Use room temperature Yogurt, Milk and Eggs
Microwave these too for about 5 seconds if you took them out of the fridge, otherwise they will make the coconut oil harden.

Whisk wet ingredients well to prevent any chunks of yogurt in the batter.

Don’t over-mix the wet and dry mixture or the loaf will be too dense and gummy because protein powder can make a batter tough.

For the perfect bakery style cinnamon zucchini muffin:

Bake for 5 minutes at 375°F then lower the heat to 350°F to and continue to bake for another 13 minutes (the total time should be about 18 minutes, until a tester inserted into the center comes out dry).
That initial hot air makes the tops rise, and then the lower temperature lets the muffins continue to cook on the inside.

Alternatives for the Best Healthy Zucchini Muffins

For the perfect healthy cinnamon zucchini muffins, I would highly suggest using the ingredients and protein powder I recommended; I do have some alternatives you can try.
I haven’t testing them all, so I can’t say how your loaf might turn out.

1:1 Gluten Free Baking Flour: All purpose flour or Whole Wheat Pastry Flour in the same amount by weight not cups.
Unflavored Protein Powder: More flour, but also reduce the milk to about 6 Tbsp.
Greek Yogurt: Coconut Yogurt
Applesauce: Mashed Banana or Pumpkin Puree
Almond Milk: Any other milk
1:1 Zero Calorie Sugar Replacement: Regular confectioners sugar or coconut sugar (this won’t be sugar free though)
