Can I make these Cosmic Brownie Crumble Cookies without protein powder?

Yes! You can substitute the protein powder with extra cocoa powder or almond flour. The cookies won’t have the same 20g protein boost, but they’ll still be fudgy, chocolatey, and delicious.

How do I store homemade Cosmic Brownie Crumble Cookies?

Keep them in an airtight container at room temperature for 2–3 days or refrigerate for up to a week. For longer storage, freeze unfrosted cookies and frost after thawing.

Are these Cosmic Brownie Crumble Cookies healthy?

Compared to traditional Crumble cookies, this recipe is much healthier—low in sugar, higher in protein, and made with simple ingredients like Greek yogurt, cocoa powder, and pumpkin purée.
