Swirl Cake (Breakfast Pie Bars)

You can bake these and then freeze the whole batch.  Then for breakfast you just pull out the pan, reheat them in the oven or microwave and serve.  We made these ones with apple pie filling.  They were oh, so yummy!

1 cup butter
1 3/4 cup sugar
4 eggs (one at a time)
1 tsp vanilla
1 1/2 tsp baking powder
3 cups flour
1 large can of pie filling (any flavor)

Mix above ingredients.  Spread 2/3s of the batter on a greased and floured cookie sheet.  Spread with pie filling and dot with remaining batter.  Bake at 350 degrees, for 45 minutes.  (If you want, you can drizzle with a powdered sugar glaze; however, they are definitely sweet enough without; especially for breakfast.)
