For cookie dough, mix all ingredients in a bowl until a dough forms, then roll 2-4 tbsp balls and place on a baking sheet with parchment paper and place in the refrigerator for 1-2 hours. Then remove cookie dough from the refrigerator.
In a high power blender or food processor, add in all nice cream ingredients and blend until smooth.
Fold in some cookie dough bites but save some to top on the nice cream.
Line a bread pan with parchment paper and scoop the mixture into it. Top with additional cookie dough balls.
You can either enjoy the nice cream right away or store in the freezer to enjoy at a later time. To store in the freezer: cover the bread pan tightly with plastic wrap.
