In a large mixing bowl, cream together butter and sugar.
Add eggs and beat until light and fluffy.
Add almond extract.
Stir in flour and baking powder and mix until smooth.
Butter a 9 x 13 cake pan and pour mixture into pan.
Spoon pie filling all over the cake spreading out evenly - my spoonfuls were about 1 1/2 tbsps, with some smaller ones in between.
Bake at 350 for 45-50 minutes or until golden.
Top with whipped cream. Enjoy.
