Mix together peanut butter, vanilla and marshmallow cream.

Stir in Rice Krispies.

Put about one teaspoonful (roll into a ball, of desired) onto about 30 pretzel.

Squish another pretzel on top and place them in the freezer for 15 minutes to harden.

Melt white chocolate chips and shortening in the microwave for one minute. Stir until smooth. (Microwave for an additional 15 seconds, if necessary.)

Dip one half of the pretzel cookies into the white chocolate. Place them on parchment paper and add some sprinkles.
