These protein cookies are a simple and tasty treat made with just four ingredients. They’re soft, a little chewy, and packed with protein to help keep you going throughout the day. The ingredients are easy to find and mix together quickly, which makes these cookies a great option when you want something sweet but also a little bit good for you.
I love making these cookies when I want a quick snack after a workout or whenever I need a little energy boost. The best part is you can customize them with your favorite mix-ins like chocolate chips, nuts, or dried fruit, but even plain, they taste great. I usually whip up a batch and keep them in my pantry for whenever I need a grab-and-go bite.
When I serve these cookies, I like to enjoy them with a glass of milk or a cup of coffee—it makes for a nice little break in the day. They’re perfect for sharing with friends or bringing along to work or school. Every time I make them, people ask for the recipe because they’re just that good and easy to make.
Key Ingredients & Substitutions
Peanut Butter: Natural peanut butter gives great flavor and moisture. If you’re allergic or want variety, try almond butter, cashew butter, or sunflower seed butter.
Protein Powder: Vanilla or chocolate protein powder works best here. I prefer whey or plant-based powders like pea protein. If you don’t have protein powder, you can try oat flour, but the protein boost will be less.
Brown Sugar or Coconut Sugar: Brown sugar adds a nice sweetness and slight chewiness. Coconut sugar is a good alternative with a lower glycemic index. For sugar-free, you can use a natural sweetener like erythritol or monk fruit.
Egg: It’s the binder that holds the dough together. For a vegan option, try a flax egg (1 tbsp flaxseed meal + 3 tbsp water) but the texture will be a bit different.
Chocolate Chips: Dark chocolate chips add richness and texture. You could swap with dairy-free chips, chopped nuts, or dried fruit based on your taste and dietary needs.
How Do You Get Soft, Chewy Protein Cookies Every Time?
The key is balancing moisture and baking time so cookies stay soft, not dry. Here’s how I do it:
- Use natural nut butter with some oil—it helps keep the cookies moist.
- Don’t overmix the dough, just combine the ingredients till uniform.
- Scoop dough into equal portions so cookies bake evenly.
- Bake at 350°F (175°C) but watch closely. 8-10 minutes is enough for them to set but stay soft.
- Let them rest on the pan for 5 minutes after baking; they firm up but stay chewy inside.
This simple technique gives you protein-packed cookies that are soft on the inside and slightly crisp on the outside—just how I like them!
Equipment You’ll Need
- Baking sheet – a flat tray to bake your cookies evenly without sticking.
- Parchment paper – stops cookies from sticking and makes cleanup easy.
- Mixing bowl – a large bowl to quickly combine all your ingredients.
- Spoon or cookie scoop – helps portion dough evenly for uniform cookies.
- Wire cooling rack – lets cookies cool down evenly without getting soggy.
Flavor Variations & Add-Ins
- Swap peanut butter with almond or cashew butter for a different nutty taste.
- Try chocolate or vanilla protein powder to change the flavor base.
- Add chopped nuts like walnuts or pecans for extra crunch and nutrition.
- Mix in dried cranberries or raisins if you want a sweet, chewy contrast.
The BEST Protein Cookies (4 Ingredients!)
Ingredients You’ll Need:
Main Ingredients:
- 1 cup natural peanut butter (or any nut butter of your choice)
- 1 cup protein powder (vanilla or chocolate flavor works well)
- ½ cup brown sugar or coconut sugar
- 1 large egg
- ½ cup dark chocolate chips (plus extra for topping)

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and 8-10 minutes to bake. Allow an additional 5 minutes to cool the cookies on the baking sheet. Overall, you’ll have delicious, protein-packed cookies ready in under 25 minutes.
Step-by-Step Instructions:
1. Prepare Your Oven and Baking Sheet:
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent the cookies from sticking and to make cleanup easier.
2. Mix the Cookie Dough:
In a large bowl, combine the peanut butter, protein powder, brown sugar, and egg. Stir everything together until you have a thick, uniform dough. Then, fold in the chocolate chips, distributing them evenly throughout the mixture.
3. Shape and Prepare Cookies for Baking:
Scoop out tablespoon-sized portions of dough, roll them into balls, and place them onto the prepared baking sheet. Gently press down each ball to slightly flatten it. Add a few extra chocolate chips on top of each cookie and lightly press them in. If you like, sprinkle a tiny pinch of flaky sea salt over each cookie for a nice flavor contrast.
4. Bake and Cool the Cookies:
Bake your cookies for 8-10 minutes, or until their edges are set and they turn a light golden color. Once baked, let them cool on the baking sheet for about 5 minutes. This step helps the cookies firm up while remaining soft and chewy inside. Afterward, transfer them to a wire rack to cool completely.
5. Enjoy Your Protein-Packed Treat:
Your protein cookies are ready! They make a delicious, soft, and chewy snack with a rich chocolate peanut butter flavor. Feel free to customize by swapping nut butters or protein powder flavors, or adding nuts and dried fruits to make them your own. Perfect for a quick energy boost anytime!
