Crush the cookies into small pieces. Add softened butter and mix well. Then add cacao and mix. Then add condensed milk and mix everything well. Place the resulted mix on a food plastic, form the sausages and place in the freezer for 3-4 hours. Cut the finished sausages into slices.
This was delicious! Thanks to comments by others: I cooked the sausage for 20 minutes, In the sauce: I cut the brown sugar to 1/4 cup and added 1 garlic clove to the sauce. Added sauteed cabbage to the sausage and then covered with sauce, and baked. I served it over mashed potatoes. YUM!
