Candy Bar Cookie Cake is a great way to use up leftover Halloween Candy or just make to serve a crowd of chocolate lovers.


  • 2 sticks, 1 cup, unsalted butter, melted
  • 1 cup light brown sugar, packed
  • 1 cup sugar
  • 1 large egg plus 2 egg yolks, at room temperature
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 1/4 cup cornstarch
  • 1/2 teaspoon salt
  • 2 cups leftover Halloween candy, roughly chopped (use mini candy bars, m&ms, peanut butter cups, etc)
  • For the chocolate frosting:
  • 4 tablespoons unsalted butter, very soft
  • 1 and 1/2 cups confectioners sugar, more if needed
  • 1/3 cup plus 2 tablespoons unsweetened cocoa powder
  • 2 tablespoons heavy cream, more if needed
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla


    1. Preheat oven to 350 degrees (F). Lightly spray a 9" glass pie plate with non-stick baking spray; set aside.
    2. In a large bowl add the melted butter, brown sugar, and granulated sugar; beat well until combined. Cool for 5 minutes, then beat in the egg, egg yolks, and vanilla.
    3. Add in the flour, cornstarch, and salt and mix until just combined. Be sure not to over mix here! Fold in the chopped candy bars.
    4. Spread the mixture into the prepared pie plate, smooth the top, and bake for 35 minutes, or until the top is golden brown, the edges are completely set, and the center of the pie is only slightly jiggly.
    5. Top the warm cookie cake with extra candy, if desired. Transfer cookie cake to a wire rack to cool for at least one hour and then add chocolate frosting and top with additional candy if desired.
    6. For the Fudge frosting:
      Sift together the confectioners' sugar and cocoa powder.
    7. Beat the butter on medium-high speed until creamy; about 2 minutes. Reduce speed to low and slowly add the sifted sugar/cocoa powder, alternating with the cream, then add the vanilla and salt. Beat on high speed until light and creamy, about 2 minutes.
    8. Spoon frosting into a frosting bag fitted with an open star tip and pipe onto the cooled cake.


Our middle did appear a little undercooked but the kids liked it that way.
