Spread the top of each rice cake with one tablespoon of peanut butter and lay them on a sheet pan.
Freeze for about 15 minutes while you melt your chocolate chips.
Melt your chocolate in a double boiler or in the microwave, stirring every 20 seconds.
Next, spoon over some melted chocolate to top the peanut butter as shown.
Sprinkle with peanuts if desired and freeze for 5 more minutes, or until the chocolate is set.
Enjoy!
