Pistachio Amaretto Martini is the perfect martini to serve this Christmas season! This delicious upgrade to a Pistachio Martini is a creamy cocktail that is livened up with an amazing garnish of chocolate sauce and crushed pistachios. Sounds incredible, right? It is! And the best things about making a dessert martini is it take less than 5 minutes to make, easy cleanup, and you don't have to share with your children!
