To make a super easy peanut chocolate chip cookie pie recipe, combine the following ingredients: Preheat the oven to 350?F (176?C) and grease and flour two 9-inch pie pans. Beat the butter and sugar with an electric mixer on medium speed until light and fluffy, about 2 minutes. Add the egg and vanilla and beat until combined. Gradually beat in the flour mixture, scraping down the sides of the bowl as needed. Pour the mixture into the greased pie shells and bake for 35 to 40 minutes, or until the crust is golden brown. Remove from oven and allow to cool before serving.
