These gooey protein chocolate chip cookies are soft, thick, and packed with 12 grams of protein and only 7 grams of sugar - but they taste like a real bakery cookie, not a protein bar. The secret is an extra egg yolk and a short dough rest, which keeps them fudgy and chewy rather than dry and cakey.

I've developed a lot of protein desserts - my protein mug cake, mini protein cheesecakes, cottage cheese chocolate mousse - and the mistake I kept making early on was treating protein powder like a magic add-in. It's not. It dries things out if you don't adjust the rest of the recipe around it.
That's what makes these cookies different. An extra egg yolk adds richness, a touch of coconut oil keeps the center fudgy, and a short dough rest lets the protein powder fully hydrate before baking. These small details are what separate a gooey, bakery-style cookie from a dry, crumbly one.
As a former Division I rower and Ironman triathlete, I eat a lot of protein - but I also refuse to eat something that tastes like a chalky protein bar disguised as a cookie. These healthier protein cookies check both boxes, and they've become one of my most-requested recipes from friends who don't even track macros.

The Secret to Gooey Protein Cookies
Most protein cookies turn out dry or cakey because protein powder absorbs a lot of moisture - you can't just add it and expect it to work. Here's what I do differently to make them taste similar to my gooey healthy chocolate chip cookies:
- Extra egg yolk - adds fat and richness that keeps the center fudgy
- A touch of coconut oil - prevents that dry, crumbly texture
- 5-10 minute dough rest - lets the protein powder hydrate before baking
- Pull them out early - when centers still look soft, they'll firm up as they cool
Ingredients You'll Need
- Natural peanut butter (or cashew butter) - use a stir-together creamy style, not the no-stir kind. Drippy natural peanut butter will make the cookies spread too thin. Cashew butter works if you want a milder flavor.
- Brown sugar (or coconut sugar) - less than half the sugar in most protein cookie recipes, and it still gives you that classic chewy texture.
- Eggs + an extra egg yolk - the extra yolk is key. It adds fat and richness that keeps the centers gooey instead of cakey.
- Melted coconut oil - a small amount goes a long way. It coats the protein powder, so it doesn't dry out the dough.
- Oat flour - adds light structure. I use oat flour in a lot of my baking, like my oat flour chocolate chip cookies - it keeps things soft and naturally gluten-free.
- Whey protein powder - vanilla works best here. Avoid powders with xanthan gum or thickeners - they absorb too much moisture and make cookies tough. A simple whey isolate or concentrate gives the best texture.
- Chocolate chips - I use semi-sweet, but dark chocolate chunks work too. Press a few extras on top right before baking, so they melt and look bakery-style.
- Baking soda, salt, and vanilla extract

Ingredient Substitutions & Variations
- Make them nut-free: Swap the peanut butter for sunflower seed butter. The texture and fat content are similar, so the cookies hold up the same way. Just check that your brand isn't too runny.
- Make them dairy-free: Use a plant-based protein powder and dairy-free chocolate chips. The coconut oil already keeps this recipe mostly dairy-free.
- No peanut butter flavor: Use cashew butter for a milder, more neutral taste. The cookies will be slightly softer but still chewy.
- Different protein powders: Whey isolate, whey concentrate, and most plant-based powders all work here. Plant-based powders tend to absorb more liquid - add an extra splash of milk (1-2 teaspoons) if your dough feels too dry. I don't recommend collagen powder for this recipe - it doesn't bind the same way, and the cookies won't hold their shape.
- Want cookie dough bites instead? Try my edible protein cookie dough - it's egg-free and designed to eat straight from the bowl.
How to Make High-Protein Chocolate Chip Cookies (Step-by-Step)
- Step 1: In a large bowl, whisk together the nut butter, brown sugar, eggs, egg yolk, and melted coconut oil until smooth and fully combined.
- Step 2: Add the oat flour, protein powder, baking soda, and salt.
- Step 3: Mix with a spatula until mostly combined, then fold in the chocolate chips. Let the dough sit for 5-10 minutes so the protein powder can hydrate - this is the key to a soft, gooey texture.
- Step 4: Use a large cookie scoop (about 2 tablespoon per cookie) and place dough balls 2 inches apart on the baking sheet. Press a few extra chocolate chips on top.
- Step 5: Bake at 350°F for about 8 minutes, until the edges are lightly golden. The centers will look soft - that's perfect.
- Step 6: Right out of the oven, gently press the tops down with a spatula for that chewy, crinkly look. Sprinkle with flaky salt and let cool - they firm up as they set.
Expert Tips for Perfect Protein Cookies
- Don't skip the dough rest. Protein powder absorbs moisture slowly - if you bake right away, it steals moisture during baking, and you get dry cookies. Five minutes of resting fixes this completely.
- Use room temperature eggs. Cold eggs can cause the melted coconut oil to seize, making the dough greasy and clumpy. Pull them out 10-15 minutes before you start, or place them in warm water for 5 minutes.
- Pull them out when the centers still look underdone. They'll look too soft on the pan. That's perfect. They firm up as they cool into that thick, gooey center. Overbaking by even 1-2 minutes turns them cakey.
- Press the tops down with a spatula right out of the oven. This is how you get that crinkly, flat-top bakery look. If you let them cool without pressing, they'll stay puffy and round.
- Finish with flaky salt. Not table salt - flaky salt like Maldon. It balances the sweetness, makes the chocolate taste richer, and gives it that "these are from a bakery" look.
Troubleshooting Protein Cookies
Why did my protein cookies turn out dry or cakey? The most common cause is too much protein powder. Spoon it into your measuring cup and level it off - don't scoop straight from the bag, which packs it down and adds more than you think.
Why did my protein cookies spread too flat? Your nut butter was probably too runny. Stir it well before measuring, but if there's a pool of oil on top, pour some off. Chilling the dough for 10-15 minutes before scooping also helps.
Why are my protein cookies crumbly or falling apart? The dough needs more moisture. This usually happens with plant-based protein powders that absorb more liquid. Add 1-2 teaspoons of milk and mix until the dough holds together when pressed.
How to Store & Freeze
- Room temperature: Store in an airtight container for up to 5 days. They stay soft and chewy - just make sure the container is sealed so they don't dry out.
- Freezer: Freeze baked cookies in a single layer on a baking sheet, then transfer to a freezer bag for up to 3 months. Thaw at room temperature for 15-20 minutes or warm in the oven at 300°F until the chocolate gets melty again.
- Make-ahead dough: You can scoop the dough into balls and refrigerate for up to 2 days or freeze for up to 3 months. Bake straight from frozen - just add 1-2 extra minutes.
Frequently Asked Questions + Answers
They're a healthier alternative to regular cookies, but they're still a treat - not a meal replacement. These have 12g of protein and only 7g of sugar per cookie, which is a big improvement over store-bought options that are often loaded with artificial sweeteners and fillers.
I wouldn't recommend it. Protein powder absorbs moisture differently from flour, so just adding it to a traditional recipe will dry out the cookies. This recipe is built around the protein powder, which is why the texture works.
A simple vanilla whey isolate or concentrate with minimal ingredients. Avoid powders with xanthan gum or thickeners - they absorb too much moisture and make cookies tough. I don't recommend collagen powder here either, as it won't bind properly.
Store in an airtight container at room temperature for up to 5 days. You can also freeze them for up to 3 months - just thaw at room temperature or warm in the oven at 300°F for a few minutes.
Yes - use cashew butter for a milder flavor or sunflower seed butter for a nut-free option. Avoid very runny butters, as they'll cause the cookies to spread too thin.
