Turn your slow cooker on low. I recommend using a slow cooker liner, to make your cleaning a breeze! Your chocolate should be melted in 30 -45 minutes. Keep an eye on it, and stir occasionally.
Pour your white melting chips & your white chocolate chips in your slow cooker. Check on them every so often and stir.
Once your chocolate has melted, pour half a bag of pretzels in your melted white chocolate.
Once they are all covered with the melted chocolate, place the pretzels on wax paper (on a baking sheet) and add your crushed peppermint candies.
Allow time for the white chocolate to get hard, and for the peppermint to attach.
Store in air tight container for about 5 days - if they last that long!
