Preheat the oven to 375 degrees.
Prepare a baking sheet by lining it with parchment paper.
Take the saltines and completely line the bottom of the baking sheet.
Add the butter and brown sugar to a medium saucepan and bring to a boil over medium heat stirring occasionally.
Once the sugar and butter come to a rapid bowl, start a timer and allow it to boil undisturbed (no stirring) for 5 minutes.
After 5 minutes, remove it from the heat and pour the entire mixture over the saltines using a spatula to evenly distribute and coat the crackers.
Sprinkle the chopped pecans evenly over the crackers.
Place in the oven and bake for 6-8 minutes or until bubbling all over.
Once baked, remove the tray from the oven and carefully separate the crackers and use a metal turner to place the individual crackers on a separate baking sheet lined with parchment.
To prepare to pipe the chocolate chips, take two sandwich Ziploc baggies and place one inside of the other to protect yourself from the hot chocolate. Open them up and place the bags inside a glass and fold the top of the baggie over the mouth of the glass to make it easy to pour in the melted chocolate.
Place the chocolate chips in microwave safe bowl. Cook at 50% power for 30 seconds at a time, stirring in between each interval, until the chocolate chips are melted and smooth.
Pour the melted chocolate into the prepared baggies and seal them shut. Snip the corner of the baggie and pipe chocolate on the top of the crackers.
Allow them to cool and set before transporting.
