Prepare the crust by mixing almond flour, cocoa powder, erythritol, and salt. Add melted butter and press into a lined baking dish. Bake for 10 minutes.
Make the cheesecake filling by beating cream cheese until smooth, then adding sour cream, erythritol, and vanilla. Mix in eggs one at a time and fold in strawberries.
Pour the cheesecake filling over the cooled crust and bake for 25-30 minutes until edges are set.
Let the cheesecake cool at room temperature for 30 minutes, then refrigerate for at least 2 hours to set.
Cut into bars and serve, optionally garnished with fresh strawberries.
