Ingredients

  • 3/4 cup salted butter
  • 3/4 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 egg + 1 egg yolk
  • 1 tbsp corn syrup
  • 1/2 tbsp vanilla extract
  • 2 cups all purpose flour
  • 1/2 cup dutch processed cocoa powder
  • 1/2 tbsp corn starch
  • 1 tsp baking soda
  • 1/2 tsp salt

Toppings

  • 4 oz heavy whipping cream
  • 1 cup semi sweet chocolate chips
  • 1/3 cup candy coated chocolate chips

Instructions

  • Preheat your oven to 350° F.
  • In the bowl of a stand mixer or with an electric hand mixer, cream together the butter, brown sugar and granulated sugar until well combine. Scrape the sides of the bowl.
  • Add in the egg and egg yolk, corn syrup and vanilla extract. Mix until well combined.
  • Add the all purpose flour, cocoa powder, corn starch, baking soda and salt. Mix until a soft dough forms.
  • Portion your dough into small 1 1/2 tbsp portions. Roll into a ball and then flatten slightly so it looks like a hockey puck.
  • Arrange on a parchment or silicone lined cookie sheet.
  • Bake at 350° for 8-10 minutes or until the cookies spread slightly and the edges start to crack. Pull the cookies out of the oven and let the cool on the pan.
  • While the cookies are cooling, make the frosting.
  • In the microwave, heat 4 oz of heavy whipping cream (1/2 cup) until boiling (about 30 seconds).
  • Once heated, pour the semisweet chocolate chips into the cream and allow them to sit for 5 minutes.
  • Stir until smooth, if the chocolate isn't completely melted, microwave the mixture for 15 seconds and then stir smooth.
  • Once the cookies are cool and the frostings are thicker and spreadable, spread a generous amount of frosting onto each cookie.
  • Immediately sprinkle with the candy coated chocolate chips.
  • Store in the refrigerator for up to 5 days or in the freezer for 3 months.
