Ingredients
- Ripe Bananas. They serve as the natural sweetener and base, creating that signature banana cookie flavor while binding everything together without any added sugar.
- Old Fashioned Rolled Oats. They provide the chewy texture and fiber that make these cookies filling and give them a substantial cookie-like bite.
- Vanilla Protein Powder. It boosts the protein content while complementing the banana and cinnamon flavors perfectly for a dessert that actually supports your goals.
- Cinnamon. It adds warmth that makes these taste like a classic banana bread cookie and enhances the natural sweetness of the bananas.
- Vanilla Extract. It deepens the overall flavor profile and rounds out the banana taste so these don’t just taste like mashed bananas.
- Egg. It acts as a binder to hold everything together since there is no traditional flour or butter in this recipe.
- Salt. A small pinch balances the sweetness and brings out all the other flavors so nothing tastes flat.
- Chocolate Chips. They fold in for those satisfying melty pockets of flavor that turn these from a health snack into an actual cookie.

Tips
-
Choosing Ripe Bananas
Make sure your bananas are fully spotted and soft when mashing. The riper they are, the sweeter these cookies will be without needing any added sugar. -
Cookie Dough Consistency
If your dough feels too wet to shape, let it sit for 5 minutes before baking. The oats will absorb some of the banana moisture and make shaping much easier. -
Uniform Cookie Size
Use a cookie scoop or measuring spoon to portion your dough so all the cookies bake evenly and look consistent. -
Storage
Store leftovers in an airtight container at room temperature for up to 3 days. These also freeze well for quick on-the-go snacks. -
Preventing Spread
If your cookies spread too much on the baking sheet, pop the dough in the fridge for 10 minutes before shaping. Colder dough holds its shape better. -
Protein Powder Swaps
Different protein powder brands absorb moisture differently. If your dough seems too dry, add a splash of milk or another quarter of a banana to bring it back together.
FAQs
-
Are these banana oatmeal cookies actually high in protein?
Yes, each cookie contains around 4 grams of protein thanks to the vanilla protein powder and egg. While that is not as high as some of our other recipes, it still adds a meaningful protein boost compared to regular cookies that have less than 2 grams per serving. -
Can I make these cookies without protein powder?
You can, but they will not be high protein anymore. The recipe will still work as a banana oat cookie, just skip the protein powder and add 2 extra tablespoons of oats to keep the texture balanced. You will miss out on the protein boost though. -
How do I store banana oatmeal protein cookies?
Keep them in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. They also freeze beautifully for up to 2 months, so you can batch make them and grab what you need throughout the week. -
Can I freeze these protein cookies before baking?
Absolutely. Shape the dough into cookies on your baking sheet, freeze them solid for about an hour, then transfer to a freezer bag. Bake straight from frozen at 350°F for 15-18 minutes instead of the usual 10-15. -
What protein powder works best for these cookies?
Vanilla whey or whey isolate blends work great since they complement the banana and cinnamon flavors. Plant-based vanilla protein powders work too, though you may need a touch more liquid since some plant proteins absorb more moisture. -
How many calories are in these banana oatmeal protein cookies?
Each cookie runs about 90 calories with 4 grams of protein, depending on the specific brands and sizes you use. The nutrition can shift slightly based on your banana size, protein powder brand, and how many chocolate chips you pack into each cookie.
