Peanut butter cup ice cream

I used the recipe of the machine:
http://www.cuisinart.com/share/pdf/manuals/ice-21_recipe.pdf
It's quite easy: you mix in a bowl 1 cup of not natural peanut butter and 2/3 cup of granulated sugar until you get it smooth. Then you add 1 cup of whole milk and mix it until the sugar dissolves. You stir 1 teaspoon of imitation vanilla extract and 2 cups of heavy cream. You refrigerate it for 2 hours. Then you pour the mixture in the ice cream maker for 20 minutes, you add 15 chopped miniature peanut butter cups and roll it for 5 more minutes, never interrupting the rock and rolling of the machine. Finally you set it in the freezer for 3 or 4 hours or overnight.

Supercreamy and decadent...
