Make the cake according to the box, but instead of water and oil use the pie filling. Meanwhile make the creamy layer by mixing the pudding and heavy cream. Let the mixture thicken and then fold in the 1st cup of cool whip. Once the cake is finished baking let it cool and cut into small squares. Layer the cake with the cool whip mixture until it reaches the top of the trifle bowl. Add the white chocolate shavings, raspberries and the bunny! Enjoy!
