If you want to create our rainbow effect, separate the Supernatural Rainbow Chocolate Chips by colour before you start this recipe. For our rainbow gradient, we started at the pink end and spread the melted pink chips with an offset spatula. Then we wiped off the spatula and blended the melted pink and yellow chips where they met. Wiped off the spatula again, then spread the melted yellow chips. Wiped; blended yellow and green. You get the idea!
