This adorable treat is the perfect holiday project to tackle with the kids.
Line a 15- x 10-inch jellyroll pan with parchment paper. Line prepared pan with graham crackers.
Place white chocolate melting wafers and chopped white chocolate baking bar in a medium microwavable bowl. Melt on MEDIUM (50%) power for 2 minutes, stirring every 30 seconds, or until melted and smooth. Using a small offset spatula, spread melted chocolate evenly over graham crackers until smooth. Let stand until hardened, about 20 minutes.
Melt green candy coating disks according to package directions. Spoon into a small zip-lock freezer bag. Snip a small hole in corner of bag. Pipe a "light string" over hardened white chocolate. Attach green candy halves to top of peanut candy pieces, pressing lightly to adhere to top of candy. Pipe a small dot of melted green disks to candy and attach to "string" to resemble Christmas lights.
