In another bowl, cream the butter and brown sugar using an electric mixer. Add the eggs one at a time, beating until the mixture becomes smooth and creamy. With the mixer on low speed, add the dry ingredients, alternating with the date mixture. Pour into the pan. Bake until a toothpick inserted in the centre comes out clean, 25 to 30 minutes. Remove from the oven. If desired, place the pan on a baking sheet to catch any icing that might spill over. Set the oven to broil.
