These Nutty Protein Cookies are the kind of quick bake I like when I want something sweet, simple, and a little more filling than a standard cookie. They’re made with oats, plant-based protein powder, peanut butter, applesauce, and maple syrup, so the ingredient list stays short and the prep is about as easy as it gets. You only need around 10 minutes to mix and shape them, then the oven does the rest.

You only need a handful of ingredients:
You may also want an extra 1 to 2 tablespoons applesauce if your cookie dough feels too dry.
Try my Salsa Verde Traybake recipe.
Start by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper.
Grab a small mixing bowl and add the quick oats and vanilla protein powder. Give them a good stir so everything is evenly mixed.
In a second bowl, whisk together the peanut butter, applesauce, and maple syrup until smooth.
Now pour the peanut butter mixture into the oats and protein powder.
Mix everything together until you've got a thick cookie dough.
If it still looks a little too dry or crumbly, don't panic. Protein powders vary quite a bit, so simply add another 1 to 2 tablespoons of applesauce, a little at a time, until the dough holds together nicely.
Once the mixture is ready, roll it into roughly 1-inch (2.5 cm) balls.
Place the balls onto your prepared baking sheet, leaving a little space between each one.
Use a fork to gently flatten each ball into a cookie shape. These won't spread much in the oven, so give them the shape you want now.
Pop the tray into the oven and bake for around 12 minutes, or until the cookies are lightly golden.
Transfer them to a wire rack and let them cool before digging in.
That’s it. Five ingredients, one batch of nutty little protein cookies.

Peanut butter: Almond butter, cashew butter, or sunflower seed butter can all work.
Vanilla protein powder: Chocolate protein powder is an easy way to change the flavor.
Quick oats: Rolled oats can work, although the finished cookies may have a slightly chewier texture.
Maple syrup: Agave syrup or another liquid sweetener can be used.
Applesauce: Mashed ripe banana is an easy substitute, though it will add a noticeable banana flavor.
Plant protein powder: Use your favorite pea, soy, rice, or blended plant-based protein powder.
Try my Spiced Zucchini and Chickpea Fritters recipe.
Add chocolate chips: A small handful of dark or dairy-free chocolate chips is always a good idea.
Make them extra nutty: Fold in chopped peanuts, almonds, or walnuts.
Add cinnamon: Half a teaspoon of cinnamon gives them a warm, cozy flavor.
Go chocolate: Use chocolate protein powder and add a teaspoon of cocoa powder.
Add coconut: Stir in some shredded coconut for extra texture.
Add dried fruit: Raisins, chopped dates, or dried cranberries work well.
Add a pinch of salt: If your peanut butter is unsalted, a tiny pinch of salt can make the flavors pop.
Try my Sweet Potato, Kale and Quinoa Buddha Bowl recipe.
Watch the dough texture. Protein powder can absorb moisture differently from brand to brand, so be ready to add a little extra applesauce.
Don't overbake them. These cookies can dry out quickly if they stay in the oven too long.
Flatten before baking. They won't spread much, so shape them before they go into the oven.
Let them cool. The cookies will firm up as they cool, so give them a little time before moving or eating them.
Use natural peanut butter that is well stirred. If the oil has separated, mix it back in before measuring.
Measure the protein powder carefully. Too much can make the dough dry and chalky.

Peanut butter and oats are both inexpensive pantry staples, especially if you buy larger containers.
Protein powder is probably the most expensive ingredient here, so use whichever plant-based powder you already have rather than buying a specialty flavor just for this recipe.
Store-brand applesauce and maple syrup work perfectly well.
If maple syrup is expensive, agave or another liquid sweetener may be more budget-friendly depending on where you shop.
You can also skip fancy add-ins completely. These cookies are plenty tasty as written.

These cookies are easy to enjoy on their own, but you can also pair them with:
They also work nicely as a quick post-workout snack or something to grab when you need a sweet bite between meals.

Room temperature: Store the cookies in an airtight container for up to 3 days.
Refrigerator: Keep them chilled for up to 1 week.
Freezer: Freeze the cooled cookies for up to 2 months. Place parchment between layers if stacking.
To thaw: Leave them at room temperature for a short while or thaw overnight in the refrigerator.
Reheating: These cookies don't really need reheating, but if you like them warm, microwave one for about 10 seconds.

These Nutty Protein Cookies are simple, fast, and incredibly handy to have around when you want something sweet without making a full dessert production out of it.
The peanut butter gives them plenty of rich, nutty flavor, the oats add texture, and the protein powder makes them a little more substantial than your average cookie. I also like how easy they are to tweak depending on what’s already in the pantry.
Keep them simple, add chocolate, throw in some chopped nuts, or make a double batch and stash a few in the freezer. They’re the kind of small recipe that can quickly become a regular.
These Nutty Protein Cookies combine oats, peanut butter and plant protein powder in an easy five-ingredient cookie that's ready in about 22 minutes.
Allow the cookies to cool before serving.Estimated GI ~ 38
