Line a 15x10x1-inch baking sheet with the saltine crackers. Set aside. Preheat oven to 375°F.
In a small saucepan over medium-high heat, melt butter. Add in sugar and bring to a rolling boil, stirring constantly. Once it begins to boil, remove from heat.
Pour over saltine crackers. Place in a 375°F oven for about 10 minutes, until crackers are browned and caramelized.
Sprinkle with white chocolate chips and allow to sit for several minutes (until they melt). Spread with a spatula evenly over crackers and immediately sprinkle with crushed candy.
Allow chocolate to set and store in airtight container for up to 5 days.

Notes
**to prevent the crackers from sticking to the pan you can line it with parchment paper, or remove them using a metal spatula before they harden completely (placing them on a piece of parchment on your counter, or on foil on your counter)
