Ingredients

Instructions

  • Preheat your oven according to your cookie’s recipe’s directions. Line a cookie sheet with parchment paper or a silicone baking mat.
  • Roll out your sugar cookie dough so that it’s about ¼ of an inch thick. Using your circle cookie cutter, cut out 12 circles.
  • Place each cookie on lined cookie sheet and bake according to recipe’s directions.
  • Allow the cookies to cool completely on a wire cooling rack.
  • In a small bowl, beat together butter, icing sugar and milk using an electric mixer. These ingredients will make up your buttercream frosting.
  • Once the ingredients are well-combined, smooth and form semi-stiff peaks, add blue gel food coloring.
  • Mix until it’s completely tinted.
  • Use an offset spatula to frost each cookie.
  • Now, it’s time to create your fondant rainbow. Start with your red fondant and work your way to the violet fondant, in the order listed above.
  • Grab a small portion of your red fondant, and roll out a strip, about 3 inches long. Arch it on top of one of your cookies.
  • Do the same with the rest of your colors, placing it just below its appropriate color. Trim on the sides where you see necessary. Repeat for every cookie.
  • Place 2-3 mini marshmallows at either end of your fondant rainbow. Enjoy!
