Place in mixing bowl and mash with fork.

Add sifted powdered sugar, small amounts at a time.

Mix well.

Add enough powdered sugar til forms into dough. (Will take awhile and a lot of powdered sugar!)

Place dough onto lightly "floured" surface (using powdered sugar instead of flour).

Roll out to 1/4 inch thickness.

Spread generously with creamy peanut butter.

Carefully roll dough up into long roll. Might need to cut in half. Put in fridge, covered, 1/2 hour or til firm.
