I was looking at eggless recipes and came across this one, sorry if it's a repost!
1 (3.5 ounce) package instant French vanilla pudding
6 cups milk
2-1/2 teaspoons rum flavored extract
1/2 teaspoon nutmeg
1. In a large bowl, combine the pudding mix with 2 cups of milk,
following package directions; allow to chill for 5 minutes.
2. To the pudding stir in the rum flavoring and nutmeg, then slowly
mix in the remaining 4 cups of milk until the mixture is a thick but
drinkable consistency. Chill until ready to serve.
