I've been playing around with liqueur recipes, and I think I've found an Irish Cream recipe that I like. I wanted something simple, with no exotic ingredients that could be found easily at almost any local grocers.  After searching through numerous YouTube recipes, I think I may have found one that suits me.

PawPaw's Irish Cream

Ingredients:

1 can (14 oz) Eagle brand condensed milk

14 oz half-and-half

1 T Hershey's chocolate syrup

1 T good Mexican vanilla extract

1 T good local honey

28 oz Jameson's Irish Whiskey

Prep:

In a bowl, mix it all together.  I started with the Eagle Brand and used that can to measure the half-and-half and the Jameson's.  Makes 58 oz, at 20% ABV.  It's a tiny bit boozier than store-bought (which is 17.5%) but you can adjust that if you'd like.
