Ingredients

• ¼ cup / 30g coconut flour
• 2 scoops / 60g vanilla protein powder
• ¾ teaspoon / 3g baking powder
• ½ teaspoon / 1.5g xanthan gum
• ¼ teaspoon / 1.5g salt
• 1 tablespoon / 12g chia seeds
• 1 tablespoon / 6g fresh lemon zest
• 1 ½ tablespoons / 22ml coconut oil, melted
• 1 large egg, at room temperature
• 1 teaspoon / 5ml vanilla extract
• 3 tablespoons / 45ml freshly squeezed lemon juice
• ¼ cup / 48g granulated low-carb sweetener (e.g., Stevia or Truvia blend)

Instructions

1. Directions
2. Preheat your oven to 325°F / 165°C. Line two baking sheets with parchment paper for easy cleanup and set aside.
3. In a medium bowl, whisk together the coconut flour, vanilla protein powder, baking powder, xanthan gum, salt, and chia seeds. Stir in the fresh lemon zest until evenly distributed.
4. In a separate large bowl, combine the melted coconut oil, room temperature egg, vanilla extract, fresh lemon juice, and granulated sweetener. Whisk until smooth and well-combined.
5. Pour the wet into the bowl with the dry . Mix with a spatula until a thick, cohesive dough forms. The coconut flour will absorb the liquid quickly, so avoid overmixing.
6. Using a small cookie scoop or a tablespoon, drop rounded portions of dough onto the prepared baking sheets, placing them about 2 inches apart.
7. Bake for 11–13 minutes, or until the edges are lightly golden and the centers are set. The cookies will appear soft and underdone in the middle.
8. Let the cookies cool on the baking sheets for 5 minutes before carefully transferring them to a wire rack to cool completely. They will firm up as they cool.

Pro Tips

• Using a room temperature egg is crucial! It helps the combine smoothly into a uniform batter, preventing the coconut oil from seizing and creating a better cookie texture.
• Keep a close eye on these cookies. Coconut flour bakes quickly and can go from perfect to dry in a minute. Pull them from the oven when the edges are just beginning to turn golden for the chewiest result.
• After mixing, let the dough rest for 5 minutes. This gives the coconut flour and chia seeds time to fully absorb the liquid, resulting in a better-textured, more cohesive cookie that’s easier to scoop.

FAQ

Q: Can I use a different flour instead of coconut flour
A: It’s not recommended to substitute coconut flour on a 1:1 basis. Coconut flour is extremely absorbent and unique. Using other flours like almond or all-purpose flour will significantly alter the cookie’s texture and require different liquid measurements. For the best results, stick to coconut flour for this recipe.

Q: What is the best protein powder for these cookies
A: A vanilla-flavored whey or casein blend protein powder works wonderfully as it complements the lemon flavor. You can use a plant-based protein, but be aware it may absorb more liquid, potentially requiring you to add a little extra lemon juice or water to achieve the right dough consistency.

Q: Can I make these cookies without xanthan gum
A: Xanthan gum is important for binding these gluten-free cookies and creating their signature chewy texture. If you omit it, the cookies will likely be much more crumbly. We highly recommend using it for the intended soft and chewy result.

Q: How should I store these lemon protein cookies
A: Once completely cooled, store your Zesty Lemon Protein Cookies in an airtight container. They will stay fresh at room temperature for up to 3 days or in the refrigerator for up to one week.
