Frequently Asked Questions
Can I use almond flour instead of oat flour?
Yes! Almond flour works beautifully in this recipe and gives the cookies a rich, buttery flavor and tender texture. If you’re looking for nut-free, stick with oat flour.
What kind of protein powder did you use?
I used the Be Well By Kelly Vanilla Grass-Fed Beef Protein Powder, which is non-dairy and great for baking. You can use your favorite protein powder – just make sure it’s unsweetened or mildly sweetened for best results.
Can I make these protein cookies sugar-free?
Absolutely! Swap out the maple syrup for a sugar-free alternative like monk fruit syrup or a few drops of liquid stevia. Just note that texture and sweetness may vary slightly depending on your swap.

Sam’s Recipe Tips
- For best texture, make sure your peanut butter is smooth and runny – not thick or dry.
- Don’t over-bake! The cookies firm up as they cool, so remove them once they’re lightly golden at the edges.
- Add-ins like chia seeds, flaxseed, or chopped nuts can boost nutrition even further.
Storing and Freezing Tips
Store these cookies in an airtight container at room temperature for up to 3 days, or in the fridge for up to 1 week. They also freeze beautifully – just pop them in a freezer-safe bag or container and store for up to 2 months. Let them thaw at room temp or warm slightly before enjoying.
