Preheat oven to 350°F (175°C). Grease an 8x8-inch baking pan or line with parchment.
Blend cottage cheese, eggs, melted coconut oil, and vanilla until smooth.
In a bowl, combine chocolate protein powder (or cocoa), almond flour, erythritol (or sugar), baking powder, and salt.
Stir into the wet mixture until fully combined.
Gently fold in sugar-free chocolate chips, reserving a few for topping if desired.
Pour batter into the pan, sprinkle extra chips on top.
Bake for 25-30 minutes until set but fudgy.
Cool completely before cutting into 16 squares.
