What You Need To Make These Zucchini Protein Cookies

These zucchini protein cookies come together with a short ingredient list, which is great. However, each ingredient plays a role, so sticking close to the amounts helps the texture.

Ingredient Substitutions for Zucchini Protein Cookies

Peanut butter: You can swap almond butter or tahini; however, the flavor will change slightly.
Applesauce: Mashed banana works, although it will make the cookies sweeter and softer.
Protein powder: My go-to is Vedge Nutrition (use code: EVANNRYAN to save 15% off) but you can substitute any preferred protein powder, just know protein powders differ in texture and flavour!
Oats: Regular rolled oats also work, yet sprouted rolled oats keep things a little higher in protein and fiber.

Instructions: Zucchini Protein Cookies

Preheat the oven to 350°F (175°C) and line a baking sheet with parchment.
Mix the wet base: In a bowl, stir together the grated zucchini, peanut butter, and applesauce until smooth.
Add the dry ingredients: Add the oats, protein powder, and baking powder. Next, stir until a thick dough forms.
Add chocolate (optional): If using, fold in 50 g chocolate chips. Otherwise, skip and keep them classic.
Portion and shape: Scoop into 8 mounds and gently flatten. Because these don’t spread much, shaping helps.
Bake for 10–12 minutes until set around the edges. Then cool on the tray for 10 minutes before moving.

Tips for the Best Zucchini Protein Cookies

Squeeze zucchini lightly if it’s very watery, so the dough stays thick.
Let them cool fully, because they firm up as they rest.
Adjust the dough if needed: If your peanut butter is extra runny, add 1–2 tbsp oats; conversely, if it’s too dry, add 1–2 tsp applesauce.

Frequently Asked Questions (FAQ) for Zucchini Protein Cookies

Do zucchini protein cookies taste like zucchini?
Not really. Since zucchini is mild, the peanut butter and vanilla lead, and the zucchini mostly adds moisture.

Do I need to peel the zucchini?
No. However, if the skin is thick, you can peel it. Otherwise, shredding it finely is enough.

Can I make these gluten-free?
Yes, as long as your oats are certified gluten-free and your protein powder is gluten-free. Then you’re set.

How do I store the cookies?
Store in an airtight container in the fridge for 5–7 days. Additionally, you can freeze them for up to 2 months.

Can I add chocolate without ruining the texture?
Yes. In fact, 50 g chips fold in easily, and the cookies still bake up soft and sturdy.

Can I use a different protein powder than Vedge?
You can, although the macros and texture will change slightly.
