Chocolate Chip Protein Cookies

August 16, 2026 Total time: 26 min Makes: 12 cookies

These came out of trying to solve one problem: protein cookies that do not taste like a protein bar in disguise. Blending cottage cheese right into the dough gives you a genuinely soft, moist cookie, and the melted butter still does the flavor work sugar-free versions usually miss.

Cottage cheese is doing more work here than you'd expect, blended smooth it disappears completely and leaves behind a soft, almost cakey texture that a lot of protein cookies never manage. Pull them from the oven while the tops still look a little underdone, they firm up as they cool and that's what keeps the centers soft instead of dry.

Chocolate Chip Protein Cookies

A soft, chewy chocolate chip cookie built around cottage cheese and protein powder instead of a full stick of butter.

Prep 15 min
Cook 11 min
Total 26 min
Yield 12 cookies

Ingredients

  • 1/2 cup blended cottage cheese (blend until completely smooth)
  • 3 tbsp melted butter or coconut oil
  • 1/4 cup brown sugar or brown sugar substitute
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 cup vanilla whey protein powder
  • 1/2 cup oat flour
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/3 cup mini chocolate chips, plus a few extra for topping

Instructions

  1. Blend the cottage cheese in a small food processor or blender until totally smooth with no visible curds, about 1 minute. This step matters, unblended curds will show up as odd white flecks in the baked cookie.
  2. Preheat the oven to 350F and line a baking sheet with parchment paper.
  3. In a large bowl, whisk the melted butter and brown sugar together, then whisk in the blended cottage cheese, egg, and vanilla until smooth.
  4. In a separate bowl, whisk the protein powder, oat flour, baking soda, and salt together, breaking up any protein powder clumps with the back of the whisk.
  5. Fold the dry ingredients into the wet ingredients just until combined, then fold in the chocolate chips. The dough will be soft and slightly sticky, more like a thick batter than traditional cookie dough.
  6. Scoop 12 rounded tablespoons onto the prepared sheet, spacing them 2 inches apart. Press each gently to flatten slightly, since protein cookies do not spread much on their own. Press a few extra chocolate chips on top of each.
  7. Bake for 9 to 11 minutes, until the edges are just set and the tops look slightly underdone. Do not wait for them to look fully baked, protein powder firms up as it cools and overbaking makes these dense and dry.
  8. Let the cookies cool on the pan for 10 minutes before moving them, they finish setting up during this time.

Tips & swaps

  • Full-fat cottage cheese blends smoothest and gives the softest texture. Low-fat works but the cookies come out slightly firmer.
  • A whey protein isolate can make these gummy in the center, a whey blend or a whey and casein blend browns and sets more like a real cookie.
  • These do not spread in the oven, so shape them into the size and thickness you want before baking.
  • Store in an airtight container at room temperature for 3 days, or in the fridge for a week since the cottage cheese base is more perishable than a standard cookie.
