Instructions

1 Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9×13 inch pan. Sift together the flour, baking powder, baking soda, cinnamon, nutmeg, cloves and ginger. Set aside.

2 In a large bowl, cream together the margarine, shortening and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla. Beat in the flour mixture alternately with the buttermilk, mixing just until incorporated. Pour batter into prepared pan.

3 Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool.

4 To make the Maple-Flavored Seven Minute Frosting: In a saucepan, heat maple syrup until boiling. Let boil for an additional 5 minutes. In a large glass or metal mixing bowl, beat egg whites until foamy. Gradually pour in hot maple syrup, continuing to beat until stiff peaks form.
