Heat oven to 350 degrees. Grease a 13 X 9 X 2 inch. pan.
Blend sugar, margarine, crisco, baking powder, vanilla and eggs in a large bowl on low speed. Beat on high for 3 min. Stir in flour. Spread 2/3 of the batter in the pan. Drop the cherry pie filling on the top of the batter. Then drop remaining batter on top by tablespoons on top of the cherry pie filling.
Bake until golden brown about 45 minutes, or until a tooth pick inserted into the center comes out clean. Let cool for 15 minutes. Then make glaze by stirring 1 cup of powder sugar with 1 to 2 Tbsp. of milk until smooth, then drizzle over warm cake.
