I found this recipe on mixthatdrink.com.

equal parts vanilla vodka and amaretto⁣

This is another one, like my last post, that I was looking forward to trying. This one is because I recently tried a Godfather (scotch and amaretto) and really enjoyed it, so I thought there would be a good chance I’d like this one, too. ⁣

Even though this is another “fake” martini, at least this one is all booze! No vanilla coffee creamer or rainbow sprinkles. ⁣

And, yes! It is good. I’m not really sure why it’s called a Nilla Wafer Martini, tho…I don’t really like Nilla Wafers, and I don’t see how this tastes like those dry, horrible little cookies. Well, they’re pretty good if they’re in a banana pie, but that’s the only time.⁣
