1 angel food cake, baked as directed
2 cans lemon pie filling
1 (8 oz.) Cool Whip

Cut cake twice so you have 3 circles. Place lemon pie filling on first layer. Then put second cake layer on top. Spread pie filling on this layer, too. Put top layer on. Mix remaining pie filling with Cool Whip and frost cake.

NOTE: You can use other pie fillings and just frost with plain Cool Whip, too.
