Preheat oven to 350 degrees.

Place crust ingredients into a food processor and pulse until a soft dough forms. Press dough into a greased 7" spring form pan. Bake for 12-15 mins. Let cool.

In a stand mixer, combine cream cheese and Swerve. Mix until well combined, about 3 mins. Add whipping cream and vanilla. 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. Mix xanthum gum and water. Add to berry mixture, combine well and bring to a boil. Remove from heat and allow to cool 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.
