Start by greasing your spring form pan REALLY WELL.
Press your cookie dough evenly into the bottom of the pan and bake according to package instructions.
In a large mixing bowl mix cream cheese, sugar, vanilla, and flour.
Add in eggs, sour cream and mix until smooth.
Add in M&M's and fold until well combined.
Pour batter into spring form pan.
Add water to your instant pot, and cook on high pressure for 30 minutes.
Let vent naturally for 15 minutes, and then use quick release.
Remove from instant pot.
Blot excess water with a paper towel.
Let cool completely.
Place in fridge overnight.
Top with M&M's and cookie crumbs.
Serve and enjoy!
