Zucchini Protein Muffins

You would never know that I spruced up the ingredients in these muffins by adding some protein powder to help keep you fueled and satisfied!

These muffins taste just like a slice of zucchini bread, except these aren’t heavy with oil. Each muffin is under 150 calories with about 7 grams of protein and they’re delicious!

I make sure that every day I get an adequate amount of protein in my diet. Protein helps me feel full longer, gives me a boost of energy, and keeps my appetite under control so I don’t over eat.

I eat plenty of animal proteins, but sometimes my stomach can’t handle heavier protein sources like chicken, especially after a challenging workout.

During those times I’ll get my fuel from nutrition shakes like EAS Complete Protein.

Shredded Zucchini for protein muffins

You don’t need to break out your mixer for this recipe. A strong arm with a gentle touch will do the trick when preparing these muffins!

First, shred the zucchini and take some of the moisture out by gently patting it with paper towels. You can even roll it up in a couple of layers to soak up the extra water that zucchini holds.

Whisk together the dry ingredients, including the protein powder, and then in a separate large bowl combine the wet ingredients together.

Next, incorporate all the ingredients together including the walnuts (optional) just until everything is blended. Don’t over mix or be heavy handed with the ingredients or you’ll end up with dense muffins!

  1. These sound great! Can I substitute plant-based protein powder for the whey powder? I know plant based is a bit more absorbent so wondering what I should tweak for this modification!

    1. Hi Alyssa! You can use plant based protein. I haven’t tried it though, so I can’t give you exact adjustments, but I think 1:1 ratio would work well. Let me know how it turns out for you.

      1. Update re: plant-based protein powder – they came out great! I kept the measurements the same. I used Orgain’s Vanilla plant-based protein powder and I also used Bob’s Red Mill Gluten Free baking flour to make them gluten-free. Only difference is I needed to bake them for about 22 minutes.

  2. These muffins look great. Nice and healthy. I’ve always wondered in baking with protein powder kills off the value from it. I guess not. Thanks for the recipe.

  3. There’s nothing worse than running out of energy before you’re finished biking! These muffins would be perfect for taking on a bike ride or anytine!

  4. I don’t think of muffins as a healthful option, but with the added protein these are really a delicious option! Great for breakfast or for a grab-n-go snack!!

  5. I love zucchini muffins, these sound wonderful, I love that they have additional protein too!

  6. I track my nutrition daily and my goal is to get enough protein as well as fiber and keep my carbs healthy and low fat. I love how you bumped up the protein in these muffins, they look delicious!

  7. These look absolutely DELICIOUS! I really want to stuff a couple into my facehole right now. 🙂 I love that you were creative enough to add the protein powder to the muffin batter! #client
