It pains my sister to make this drink for me. She's a real drinker - knows her alcohol, knows what to mix with what. She does NOT stock Oreos in her bar. Yet, with all the love a big sister can blend in with Kahlúa and ice cream, she makes me this every year during Siblings' Weekend. She laughs at me, but she makes it. I love you, sister. This drink is a memory I will always treasure.
