This cookie is dedicated to all you chocolate lovers out there who love a deep, dense, chocolaty, chunky cookie that is so chocolaty that it will soothe any worry or care and blow your chocolate loving mind. 3/4 cup unsalted butter, softened 1/3 cup butter-flavored shortening 1 cup granulated sugar 2/3 cup firmly packed dark brown sugar 2 large eggs 2 teaspoons vanilla extract 2 cups all-purpose flour 2/3 cup unsweetened cocoa 1 teaspoon baking soda 1/4 teaspoon salt 2 cups or 16 cream-filled chocolate sandwich cookies, coarsely chopped (I used Oreos) 3 (1.75-oz.) Mounds bars, chilled and chopped 1 to 2 cups semisweet chocolate morsels Start off by preheating the oven to 350 degrees. Line cookie sheet with parchment paper (although I was out of parchment paper and just used my non-stick cookie sheet and they came out just fine) and set aside. Using a stand mixer (or a hand mixer) beat the butter and shortening at medium speed in the stand mixer bowl until creamy; gradually add in the sugar and brown sugar, beating until light and fluffy. Add eggs one at a time and vanilla, beating until well blended. In a separate bowl, combine the flour, baking soda, unsweetened cocoa and salt, mix well. Then gradually add the dry mixture to the butter mixture, beating until blended. Next cut up the cookies coarsely, and cut up the chilled Mound bars into little squares. Then with a spoon add add in the cookies, candy bars and chocolate morsels. Once all ingredients have been incorporated completely, chill dough for 30 minutes. Once dough is chilled drop dough by 1/4 cupfuls, 2" apart onto baking sheets lined with parchment paper. These cookies are large and I only put six per cookie sheet. Depending on how fast your oven cooks, bake your cookies for 10 to 12 minutes or until barely set. Once baked, take the cookies out and let them cool for 10 minutes away from the heat of the oven. Lastly transfer the cookies to a wire rack to cool until they are just barely warm. These cookies are best slightly warm with a tall glass of milk. But would also be divine with a scoop of vanilla ice cream, fudge sauce and a dabble of whip cream. So get ready for an intense chocolate experience that will have you begging for more.
