Cookies

ingredients

  • 8 oz unsalted butter, softened
  • 4 oz granulated sugar
  • 2 oz brown sugar
  • 1 teaspoon vanilla extract
  • 1 egg
  • 1/4 teaspoon salt
  • 4 oz dark cocoa powder
  • 8 oz all purpose flour
  • heavy cream, as needed to bring the dough together, about 1/2 cup

Frosting and Assembly

ingredients

  • 1 1/2 cups semisweet chocolate chips
  • 1 cup plus 2 tbsp heavy cream
  • 1 tbsp unsalted butter
  • 1/4 cup rainbow coated mini chocolate chips

Make the Cookies

Method

  • Step 1

    In a large bowl add the softened butter and sugars. Cream together until light and fluffy.

  • Step 2

    Add the vanilla extract, and egg. Mix to combine.

  • Step 3

    Add the salt, cocoa powder, and flour to the wet mixture and mix to form a dough.

  • Step 4

    Add heavy cream as needed to bring the dough together.

  • Step 5

    Line 2 sheet trays with parchment paper. Using a standard sized ice cream scoop, scoop the dough out. Spread the scoops between the two trays.

  • Step 6

    Use a measuring cup (I used 1/3 cup) to flatten the dough scoops. If your measuring cup is sticking to the dough, grease it with a little bit of neutral oil to prevent sticking.

  • Step 7

    Freeze the cookies for 20 minutes to set.

  • Step 8

    Preheat the oven to 325 degrees Fahrenheit. Bake the chilled cookies for 16-18 minutes or until the edges begin to crisp up.

  • Step 9

    When the cookies come out of the oven, let them cool completely.

Frosting and Assembly

  • Step 1

    Pour the chocolate chips into a medium bowl.

  • Step 2

    Heat up the cream either on the stove (to a simmer) or in the microwave in 30 second increments.

  • Step 3

    Pour the hot cream over the chocolate chips to cover them and let sit for 1 minute.

  • Step 4

    Whisk to combine and form a smooth ganache. Stir in the butter.

  • Step 5

    Chill for 10-15 minutes if necessary to reach a spreadable frosting consistency.

  • Step 6

    Either spoon or pipe a swirl of the frosting onto each of the cooled cookies. Use a spoon to make a swoop in the frosting for decoration.

  • Step 7

    Top with the rainbow coated mini chocolate chips.

  • Step 8

    You can store them at room temperature for up to 24 hours. Beyond that, store in an airtight container in the refrigerator. Enjoy!
