Healthy, flourless, and full of amazing flavor, this oatmeal protein cookie is about to become your new favorite snack.

Protein Oatmeal Cookies with Bananas
Do you ever look at a packed lunchbox and think to yourself: "I have to add something else in here" or, "I need to a small something for snack time." I've experienced this scenario often until I decided to write my 240-page book The Best Homemade Kids' Snacks on the Planet.
When I set out to make this protein oatmeal cookie, I wanted to emphasize amazing flavor, but also give myself and my kids a nice boost of energy to get us through the day, instead of a sugar crash that most cookies will provide if you eat them in the middle of your day.
Ingredients
I have experimented with different protein powders and flavors for this oatmeal cookie, and nothing beats the classic vanilla protein powder (though chocolate is a close second). Then, you’ll also need bananas for natural sweetness, peanut butter, vanilla, baking powder, oats, hemp seed hearts, and chia seeds.

How to Make High Protein Oatmeal Cookies
Here’s how to make this soft and chewy protein oatmeal cookie:
- Preheat the oven to 350F and line a baking sheet with parchment paper.
- Combine mashed banana, peanut butter, vanilla, and baking powder in a large bowl.
- Make these cookies super nutritious by adding protein powder, oats, hemp seed hearts, and chia. You want to combine until you have a thick batter.
- Shape the cookies by scooping mounds onto the lined baking sheet and pressing down to shape the dough into a cookie. These cookies don't expand in the oven.
- Bake in the preheated oven for 10-12 minutes.

This looks so healthy!! Would it be possible to sub out bananas for pumpkin?
