Step 1
Cream together butter, margarine, cottage cheese, salt, and 4 cups of flour to form a dough. Shape into a large square, cover, and chill overnight.

Step 2
Preheat the oven to 375 degrees F (190 degrees C).

Step 3
Cut dough into 4 quarters. Roll each quarter out individually, about 1/8 inch thick; cut into 8-inch strips.

Step 4
Roll over tubes (I use clothespins covered with aluminum foil). Bake in the preheated oven until brown, about 10 to 15 minutes.

Step 5
Cook and stir milk and 4 tablespoons of flour together over medium-low heat until thick paste forms. Let cool completely.

Step 6
Beat shortening and confectioners' sugar together until fluffy. Add marshmallow cream and vanilla; add cold paste and beat.

Step 7
Fill tubes with cream filling. Sprinkle with confectioners' sugar just before serving.
