Cream together one cup sugar and 1/2 cup butter. Mix together with one cup pumpkin and two eggs. Then, in a separate bowl, sift together 2 cups plain flour, 4 teaspoons baking powder, 2 1/2 teaspoons cinnamon, 1/2 teaspoon ginger and 1/4 teaspoon nutmeg. Mix the sifted ingredients into the first mixture and blend thoroughly. I like to add golden raisins and coarsely chopped walnuts at this point; cranberries are also a delicious addition. I’ve even tossed in some chocolate chips from time to time. Spoon onto a baking sheet and bake at 380° for 15 minutes.
