Preheat the oven to 350 degrees.
Place crust ingredients into a food processor and pulse until a soft dough forms.

Bake for 12-15mins. Let cool.
In a stand mixer, combine cream cheese and Swerve.

Whip until mixture starts to thicken and is completely smooth, about 5 minutes.
Pour mixture onto cooled crust and spread evenly.
Place in the freezer for 3 hours or in the fridge overnight to set.
In a medium pan heat blackberries and Swerve.
Crush berries into a pulp as they cook.

Remove from heat and allow to cool for at least 5 minutes before using a hand blender to blend the berry mixture until smooth.
Pour over the cheesecake, top with fresh
blackberries and serve.
