Spread Ritz cracker with peanut butter, sandwich another Ritz on top. Do several stacks. In slow cooker melt 1/2 block of paraffin and 1 (12 ounce) chocolate chips or large block of chocolate (chocolate keeps well in your slow cooker to use later to dip other things). Dip in Ritz sandwiches, let cool on wax paper. If chocolate left over, try stirring in pecans or peanuts and drop onto wax paper to cool. Use regular or white chocolate.
