Preheat your oven to 350°F. While it heats, line an 8x8 inch baking pan with parchment paper, making sure it covers the bottom and sides for easy removal later. This step ensures your brownies won't stick and your oven will be ready to go the moment your batter is prepared.

Pour the cottage cheese into a blender and blend until completely smooth, about 1-2 minutes. This is crucial because it breaks down the curds and creates a silky base for your brownies—skipping this step will result in a lumpy, uneven texture. Transfer the blended cottage cheese to a large mixing bowl.

Add the peanut butter and vanilla extract to the blended cottage cheese, then stir well to combine. In a separate small bowl, whisk together the cocoa powder, coconut sugar, and protein powder until no lumps remain—I like to sift the cocoa powder first to remove any clumps and ensure even distribution throughout the brownies. Pour the dry mixture into the wet ingredients and fold everything together with a spatula or fork until fully incorporated and smooth.

Scoop the batter into your prepared pan and spread it into an even, flat layer using a spatula—a damp spatula works best for this and prevents sticking. Sprinkle the chocolate chips evenly across the top, pressing them down slightly so they stay in place during baking.

Place the pan in your preheated 350°F oven. For fudgy brownies with a soft, almost gooey center, bake for 15-20 minutes. For cakey brownies with a more structured crumb, bake for 25 minutes. I prefer checking at 18 minutes and using a toothpick—if a few moist crumbs cling to it, they're perfectly fudgy. Let the brownies cool in the pan for at least 10 minutes before cutting so they hold together cleanly.
