Line a large baking sheet with either a parchment paper or a silicone baking mat, then set aside.
Divide the bag of white chocolate chips into two microwave-safe bowls: one with ⅓ cup, and another with ⅔ cup. (Use disposable paper plates for easy cleanup.)
1 12 oz Bag of white chocolate baking chips
Melt the larger portion of white chocolate chips in the microwave, stopping and stirring every 20 seconds to prevent it from turning clumpy or grainy.
Once melted, pour the white chocolate onto the lined baking sheet, then spread it to form a large rectangle.
Microwave the smaller portion of white chocolate chips, stopping and stirring every 15 seconds.
Once sufficiently melted, add a few drops of green food coloring until your desired shade of green is achieved.
Green food coloring
Drizzle the green-colored chocolate in lines over the white chocolate layer on the baking sheet.
Use a toothpick to swirl.
Decorate the chocolate with gold candy sprinkles and Lucky Charms marshmallows.
¾ cup Lucky Charms marshmallows, Gold candy sprinkles
Refrigerate the bark uncovered for about 30 minutes, or until it’s firm.
Once firm and set, remove from the fridge.
Break or cut the bark into bite-sized pieces. Serve and enjoy!
