Line an 8’’ square baking dish with parchment paper.

Add all the ingredients for the crust to a medium bowl. Stir until combined.

Transfer the crust mixture into the prepared baking dish and press it down evenly. Place in the refrigerator while you prepare the filling.

Add the filling ingredients except the sour cream to a medium bowl. Use an electric mixer to mix.

Add the sour cream. Continue mixing until smooth.

Pour the filling on top of the crust, using a rubber spatula to spread it evenly. Place in the refrigerator for at least 4 hours to allow the cheesecake to set.

Once the cheesecake has chilled, add the topping ingredients to a saucepan and heat over medium heat until berries turn into a light jam. Add sweetener if desired.

Pour the jam over the cheesecake and serve immediately or refrigerate.
