Easy Gluten-Free Peanut Butter Protein Cookies
These healthy peanut butter protein cookies get a double dose of peanut butter flavor from powdered peanut butter and natural peanut butter. Maple syrup sweetens the dough, while oat flour and vanilla protein powder give the cookies structure and a little protein boost, with about 4 grams per cookie.
The dough comes together in two bowls, then gets scooped, rolled, and pressed with a fork for that classic crosshatch look. They bake in just 8-9 minutes and firm up as they cool, and a sprinkle of flaky sea salt on top makes them taste like a bakery cookie. If you're craving more peanut butter treats, my peanut butter protein balls are a no-bake favorite.
They're perfect for an afternoon snack, a post-workout treat, or a holiday cookie tray. And if you need more healthy cookies like this one, you're going to LOVE my healthy oatmeal raisin cookies or my simple breakfast cookies!

Ingredients Needed To Make These Peanut Butter Protein Cookies
Here's a little bit about everything that goes into these peanut butter protein cookies:
- Powdered peanut butter: Like PB2. It adds big peanut butter flavor with less fat. Half goes into the wet ingredients and half into the dry.
- Natural peanut butter: Gives the cookies richness and a soft, chewy texture. Creamy or crunchy both work!
- Maple syrup: Naturally sweetens the dough instead of white sugar.
- Oat flour: Gives the cookies structure. You can make your own by blending oats until fine.
- Vanilla protein powder: Adds a little protein and a hint of vanilla flavor.
- Sea salt flakes: Sprinkled on after baking for the perfect sweet and salty finish.
How to Make Peanut Butter Protein Cookies
These cookies start by whisking half of the powdered peanut butter with water to make a smooth peanut butter base, then mixing in the maple syrup, natural peanut butter, and vanilla. The dry ingredients get combined in a separate bowl, then stirred into the wet mixture until a dough forms.
Roll the dough into balls and press each one with a wet fork for that classic crosshatch pattern. Dipping the fork in water keeps it from sticking! Pull them out of the oven when they're just turning golden. They'll be soft at first but firm up as they cool.
- Step 1: Preheat the oven to 350°F and line a baking sheet with parchment paper.
- Step 2: In a medium bowl, whisk half of the powdered peanut butter with the water. Add the maple syrup, natural peanut butter, and vanilla, and whisk until smooth.
- Step 3: In a small bowl, combine the oat flour, remaining powdered peanut butter, protein powder, and baking powder.
- Step 4: Add the dry ingredients to the wet ingredients and stir until a dough forms.
- Step 5: Scoop the dough into balls, about 1.5 tablespoons each, to make about 14 cookies. Place them on the baking sheet and flatten each one with the back of a wet fork.
- Step 6: Bake for 8-9 minutes, until just golden. Let them cool, then sprinkle with flaky sea salt.
Erin's Expert Tips
From my kitchen to yours
- Use a wet fork. Dip it in water before pressing so the dough doesn't stick.
- Roll into balls first. It helps the cookies bake evenly before you flatten them.
- Don't overbake. Pull them at 8-9 minutes, when they're just turning golden.
- Let them cool on the pan. They're very soft at first and firm up as they cool.
- Salt after cooling. Sprinkle the flaky sea salt on once they've cooled so it stays crunchy.
Frequently Asked Questions

Yes! You can leave out the protein powder.
Yes, peanut butter flavored protein powder works too.
Yes, almond flour works, but you may need to adjust the amount.
Yes, but the ratios may need to be adjusted. Oat flour is recommended for the best results and to keep them gluten-free.
Measure after grinding. You'll want ⅓ cup of ground oat flour.
Yes! Creamy or crunchy natural peanut butter both work.
Make sure you're using powdered peanut butter (like PB2) where it's called for, not regular peanut butter. Using regular peanut butter in its place will make the dough too sticky.
