Set your oven to 350°F (175°C) beforehand to guarantee consistent and even baking.

Blend the cottage cheese until smooth, using a food processor or blender to avoid lumps. This will give your brownies a creamy texture.

In a spacious bowl, whisk the melted butter, granulated sugar, and brown sugar until smooth and well combined. 

Gradually beat in the eggs one at a time, ensuring each is fully incorporated before adding the next, then mix in the vanilla extract.

Fold in the blended cottage cheese, mixing it into the wet ingredients.

In another bowl, sift the flour, cocoa powder, baking powder, and salt together to create a light, uniform mixture. 

Gradually mix this into the wet ingredients, stirring until just combined.

Melt half of the chocolate chips and fold them into the batter for a rich flavor.

Add any remaining chocolate chips for extra texture, folding them gently into the mix.

Transfer the batter to a greased 9x9-inch pan and smooth the top. 

Bake for 25 minutes, then test with a toothpick, if it comes out with a few moist crumbs, it's ready.

Let the brownies cool for 10 minutes before transferring them to a wire rack to cool completely. Slice into squares and enjoy!
