Process all base ingredients into a fine sticky crumble in a food processor. Transfer into a 4" springform pan and press down into a flat even crust. Freeze while working on the next step.
Blend all filling ingredients into a smooth consistency in a power blender. Transfer the mixture into the prepared crust and smooth out the top. Tap the cake pans gently on the counter to flatten the filling. Top with fresh berries and any other toppings. Freeze for 5-6 hours or overnight to set. Enjoy!
