I was in a weird mood on Sunday night. The kind of mood that even after I had completed my Sunday chore to-do list (that which usually is the main reason for any such weekend angst, haha ), I was still just feeling off. And being someone who likes to see cause and effect, being off and not being able to figure out why I just wasn't feeling things.
So, I started walking around the house looking for something to do to get my mind off things. To hopefully be its own kind of self-care therapy.
As I walked around, I noticed overripe bananas in my fruit bowl. The sight of them alone triggered memories of a weekend a few summers prior when, in a funk, I randomly decided to make sugar cookies in the middle of July. My weekend had started afresh by the time those golden goodies were out of the oven.
So, I started to think about cookies, but I had also just made Just So Tasty's Double Chocolate Chip Cookies a few days previous. Going too sweet of a baking direction sounded like too much. To go with the obvious direction of banana bread wasn't a possibility either because I didn't have enough bananas.
Breakfast, however, had been needing some spicing up. I'd been getting in a funk. I got on Google, typed in "Breakfast Banana Cookies," browsed a recipe that got my creative juice flowing. Before you know it, this gluten-free and high protein breakfast cookie was born.
Leftover bananas, peanut butter, oatmeal, hemp seeds, and nuts combine in a protein cookie recipe. Adding sugar is only optional (see the recipe cooking notes). They come together to create a cookie that satisfies the stomach and soul. That fuels & nourishes with both flavor and nutrition. A treat that turned my night around as a product of expression that nurtures from the inside-out.
This healthy protein cookie recipe is...
- Naturally sweet
They're like trail mix cookies, but more nutritious and filling! Satisfying, but not too sweet to overwhelm those breakfast tastebuds.
Healthy breakfast cookie ingredients:
- Bananas - in particular, ripe bananas. The more brown spots on your bananas, the better!
- Vanilla extract
- Nut butter
- Vanilla protein powder- preferably a plant-based protein powder but whey-based protein powders also work
- Oat flour - a naturally gluten-free and delicious flour. See my instructions below to learn how to make this flour.
- Baking powder
- Old fashioned oats
- Hemp seeds
- Chocolate chips - use Lily's or Enjoy Life chocolate chips to cut back on sugar and/or dairy in your recipe
- Nut butter: you can substitute almond butter or sunflower seed butter in place of the peanut butter in this recipe. Whatever you and your family like and have on hand!
- Honey: don't have vanilla protein powder? Not a problem. Substitute honey (or agave syrup) in place of the powder. The flavor will be the same, but the protein count on each cookie will be slightly lower.
- Nuts, seeds, or dried fruits: have fun with the different nuts, seeds, and dried fruits you add to these cookies! Pumpkin seeds, dried cranberries, whole flax seeds, hazelnuts, and almonds are all delicious in place of the peanuts, raisins, and hemp seeds.
How do you make healthy oatmeal cookies?
First: preheat your oven to 350 degrees and line two large baking sheets with parchment paper.
Second: In a large mixing bowl, whisk together 2 large mashed bananas, your peanut butter, egg, vanilla extract, and honey (if using).
Third: Add in oat flour, salt, cinnamon, baking powder, and hemp seeds and whisk until everything is combined.
Fourth: Add in the oats, peanuts, raisins, and chocolate chips (if using) and gently stir the batter together with a rubber scraper.
Fifth: Scoop out the cookies on the baking sheets in about 2 tablespoon drops. Lightly shape or press down the cookies (they won't change much shape as they bake) and bake for 10-12 minutes, or until the cookies are golden brown on the bottom and edges of the cookies.
Sixth: cool the cookies on a wire rack and enjoy!

Protein Cookie Recipe pro-tips:
- Use overripe bananas - this adds natural sweetness and moisture to these low sugar cookies. Use bananas with a decent amount of brown spots. You don't want to use all-black bananas, though.
- Flatten the cookies before baking - these cookies will not spread when baking, so you will want to flatten or press down on them after you have scooped them. Do this with a spoon or a drinking glass sprayed with non-stick cooking spray.
- Use a cookie scooper for uniform cookies - this will change your cookie game!
- Don't overbake the cookies - since these are no butter cookies, they don't have butterfat to protect them from overbaking. So, overbaking them will make them dry and lifeless, not crispy and crunchy.
These cookies are naturally sweet. That is, they're sweet enough to enjoy for breakfast, a post-workout snack, or even a healthier evening treat, but they're not going to bowl you over with sweetness like a traditional cookie would.
If you'd rather go for a traditionally sweet cookie, I recommend you check out my Peanut Butter Chocolate Brookies, High Altitude Chocolate Chip Cookies, or High Altitude Peanut Butter Cookies.
Old-fashioned oatmeal is best for these breakfast cookies. It will provide a hearty texture to the cookies and it will also blend down well to make the oat flour for the cookies.
Just add oats to the food processor or blender and blend until the oats are fine like flour. To save on time, blend up a large batch of oats all at once. Store the oats in a dark and dry area for up to 2 months or freeze in a freezer-safe container to keep fresh for 3-4 months.
- Gluten-free: thanks to oat flour and old-fashioned oats, these cookies are gluten-free! Just make sure to use oats that are labeled gluten-free (and save money on gluten-free oat flour by making your own!).
- Vegan: You can make these cookies vegan by using plant-based protein powder (I like Orgain), a flax egg instead of a regular egg, and dairy-free or vegan chocolate chips
Are protein cookies good for breakfast?
Yes!! These cookies are fantastic for breakfast. Especially for busy mornings when you want to snag a bite on the way out the door. With whole grains, healthy fats, and dried fruits, these cookies are packed with nutritious ingredients while being super portable!
These cookies store the best in the refrigerator or freezer:
- Refrigeration: store the cookies covered in an air-tight container in the fridge for 3-5 days.
- Freezing: cookies last covered in a freezer-safe container for up to 3 months. To thaw, leave the cookies out at room temperature for 10-20 minutes or until no longer frozen.

A delicious 1-bowl chewy cookie recipe that has so much flavor it's hard to believe that it's full of plant-based protein, healthy fats, and is gluten-free!
Make sure to use two large bananas, or about 1 ¼ cups, in this recipe or else your cookies may be too dry and fall apart.
- 2 large (or about 1 ¼ cups) overripe bananas, mashed
- 1 jumbo egg
- ½ teaspoon vanilla extract
- ½ cup nut or seed butter (peanut, cashew, almond, or sunflower seed butter)
- 2 scoops vanilla protein powder (preferably plant-based)
- 1 ¾ cups oat flour (directions in notes below)
- ½ teaspoon salt
- ¾ teaspoon cinnamon
- ¾ teaspoon baking powder
- ¼ cup hemp seeds
- 1 ½ cup old fashioned oats
- ¾ cup peanuts, almonds (sliced or slivered), or cashews
- ¾ cup raisins
- ¾ cup chocolate chips (optional but encouraged)
- Preheat oven to 350 degrees and line 2 large baking sheets with parchment paper or a silpat mat.
- In a large bowl, mix together all the wet ingredients with a large fork or whisk until well combined, creamy, and the banana is mashed.
- Add in the oat flour through hemp seeds and whisk until combined.
- Add in oats, nuts, and chips and/or raisins (if using) and turn in with rubber scraper until all are evenly distributed throughout the batter.
- Scoop cookies onto the baking sheets in about 2 tablespoon drops (they will be a larger cookie) and pat the tops down lightly to shape the cookies. Bake for 10-12 minutes, or until the cookies are just starting to turn golden brown around the edges.
- Remove the cookies from the oven and let cool on a wire rack until cool enough to serve.
- 3 tablespoons honey can substitute for the protein powder, though it will impact the amount of protein in the recipe.
- To make oat flour, just blend old fashioned oats in a blender for 15-45 seconds, or until the oats are blended into a fine flour.
- The batter will be stiff when you scoop them out onto the sheet. They also shouldn't spread as they bake so re-shape so pat down the cookies and reshape before baking.
- These cookies keep covered in an airtight container in the fridge for 3-5 days or in an airtight freezer-safe bag in the fridge for 6-8 weeks.
- If you don't have hemp seeds you can substitute in pumpkin seeds or sunflower seeds.
