White chocolate bark is so much fun to make, and this recipe adds a fresh blush of color to any snack. Rainbow Marble Chocolate Bark is a delicious snack on-the-go and is equally appreciated as a gift for neighbors and friends.

This is such a simple recipe, you can make it in 15 minutes before it goes into chill. All you need white chocolate and some decorating gel from the supermarket. All you need to do is melted some white chocolate until smooth and pour onto a baking sheet lined with parchment paper.

Make some S-shape patterns with different color decorating gels, and then swirl a toothpick through to create the marble design. Then chill to harden and break apart. That’s it!

If you prefer to use natural food coloring, we suggest Watkins or McCormick brands available online. Watch our video tutorial to see how to make it from start to finish:
