Follow the box instructions to make the angel food cake
Make sure the angel food cakes cools completely and tear into bite size pieces. Set aside
Combine the milk and pudding according to the package instructions in a separate bowl
Once the pudding has set, fold about half the cool whip container into the pudding
In a large bag crush up the gingersnaps into crumbs leaving some small pieces
Get a trifle bowl and layer half the angel food cake, then half the pudding, then a good layer of gingersnap cookies. Repeat this once more. Top with the remaining cool whip and a few cookies crumbs. Then time to serve!
