Instructions

    Cup of Yum
  1. Preheat the oven to 350 degrees. Line the cookie sheets with parchment paper.

  3. In a large mixing bowl with an electric mixer, cream together the butter, white sugar, light brown sugar until fluffy.
  4. Mix in the eggs, vanilla extract, and corn syrup.
  5. Gradually add in the flour mixture until a soft cookie dough begins to form.
  6. Divide the dough into 12 portions and then roll each portion into a ball using your hands.
  7. Place the cookie balls on a cookie sheet about 2 inches apart.
  8. Flatten the cookie balls into circles using the palm of your hand or the bottom of a glass (not flat, but slightly).
  9. Bake for 15-17 minutes until the cookies start to crack and the centers are set (not wet). Let cool before frosting.
Make the Fudge Frosting
  1. In a small glass bowl, microwave the heavy cream for 1 1/2 minutes or until it is boiling (or add the cream into a small pot and bring to a simmer).
  2. Stir in the chocolate chips and let site for a few minutes. Then stir until completely melted and smooth.
  3. Spoon the frosting on each cooled cookie and immediately sprinkle the rainbow coated chocolate chips on top.
