What you need to make this giant Halloween cookie
|
Pan: A 9–10 inch pie dish or cake pan works well. A deeper dish yields a thicker, softer cookie.
Cookie mix: A 17.5 oz (large) cookie mix such as chocolate chip or sugar cookie. The smaller package can be used, but check baking time closely. Egg and butter: Most mixes call for 1 egg and 1 stick (8 tablespoons) of butter or margarine. Decorations: Canned frosting (vanilla or chocolate), Oreos, M&M’s, sprinkles, chocolate sauce, or any candy you prefer. To serve: Ice cream or whipped cream for topping. |

While I sometimes make cookie dough from scratch, a packaged mix is a fantastic shortcut for busy nights or for when you want a reliable, soft result every time. If you prefer, use your favorite homemade cookie dough and follow the same steps, adjusting baking time as needed.
How to make this fun & easy Halloween cookie cake
Preheat the oven to 350°F (175°C). Prepare the cookie dough according to the package directions — for many mixes this means combining the mix with 1 egg and 1 stick of softened butter. Press the dough evenly into the bottom of a greased pie dish or cake pan. If you like, fold in sprinkles or small broken cookie pieces before pressing the dough into the pan.

Bake at 350°F for about 15–18 minutes, or until the edges are golden and the center looks set but still slightly soft. For a softer, chewier cookie cake, you can remove it a minute or two earlier — it will continue to firm up as it cools.
How to decorate this Halloween cake
Allow the cookie cake to cool before decorating. Spoon canned frosting into a piping bag or zip-top bag with the corner snipped off and pipe a decorative edge. Add additional candies, sprinkles, or broken cookies across the surface. Slice into wedges and serve warm with a scoop of ice cream and a drizzle of chocolate sauce for an indulgent finish.
