Cook the pumpkin and when it’s cold, dry the water and mash it. Using your stand mixer, cream together margarine and sugar. Stir in pumpkin and vanilla until combined. Add flour, nutmeg, salt and baking powder and mix. Stir in chips. Divide the dough into 12 equal portions, place on parchment pape and flatten your cookies. Preheat oven to 180°C and bake the cookies for 15 minutes or until golden on top and around the edges. Wait 10 minutes before transferring them to a wire rack to cool completely.
