Now add cottage cheese, milk powder, condensed milk and coffee powder. With the help of a blender mix all ingredients.
Pour the mixture in an airtight container and freeze. After 2 hrs when the mixture hardens scoop and make small balls.
In a double boiler melt milk chocolate. Remove from heat and dip one ball at a time to coat with chocolate and then transfer it to a silicon mat or parchment paper. Decorate with sprinkles and refrigerate.
When chocolate solidifies your brownie truffles are ready to serve.
