Unwrap the Larabars and flatten them out into the pan.
For the Filling:
In a high-speed blender (I used my Vitamix), add the almond milk, peanuts, peanut butter, vanilla extract, stevia extract and salt. Blend on high until completely smooth. It will thicken slightly.
Pour in the melted cacao butter and blend again.
Add the protein powder and blend one last time.
Pour the filling over the "crust" and spread it out. Tap the pan on the counter a few times to help get rid of air bubbles. Freeze for ~3 hours, or until the surface is firm when tapped.
Use an offset spatula to separate the cheesecake from the springform. Slice and serve!
