Make sure your whisks, bowls, whipping cream and condensed milk have been chilling in the fridge for a few hours (the longer the better)
Chop the chocolate chip cookies and oreo cookies into little pieces. Set aside
Add some crushed ice into the bigger mixing bowl
Place the smaller bowl into the bigger bowl, then pour the heavy whipping cream into the smaller bowl. Add the blue food coloring
Whisk the heavy cream until you reach stiff peaks. (note: keep adding blue food color until you attain the shade of blue you like)
Once you have reached stiff peaks, pour in the cold condensed milk, and fold in gently until just combined
Next fold in the chopped cookies
Immediately pour the ice cream mix into freezer safe bowls, seal and place into the freezer for 8 hours or overnight
After 8 hours, you can scoop out the ice cream and enjoy
