Leftovers For Tomorrow's Chocolate Trifle

Okay, no I didn't invent this Trifle, but it is so beautiful that I had to put it up here! (This photo shows a trifle made by Kimberly Ray for my birthday!) I plan to make a strawberry version with Nilla Wafers and vanilla pudding, but I'm having a hard time figuring out what alcohol to incorporate. Any suggestions?

Here's the recipe for the Chocolate Trifle:

1 box chocolate cake
2 boxes chocolate pudding
Heavy cream
Kahlua
2 containers of Cool Whip
2 Scor bars (Some people use Heath bars, but Scor is better)
2 Symphony with almonds & toffee chips (This is my own addition to a pretty classic recipe)

Make chocloate cake. When preparing pudding, use heavy cream in place of milk & reduce amount by 1/3 cup for each box. (Use 1/3 cup Kahlua in its place.) It helps to make each box of pudding in its own bowl.

After making the cake, put half of it in the bottom of the trifle bowl. Sprinkle 1/3 cup Kahlua on top of the cake. Pudding goes on next (first box), then cool whip, then candy. Then you do another layer of the same: more cake with Kahlua; more pudding (second box); more cool whip; more candy. And look how pretty it is!!!! It's always an impressive dessert to bring to someone else's party - or to serve at your own!
