Creating Berry Bliss Cheesecake is a rewarding experience when you follow these steps:

1. Prepare the Oven: Preheat your oven to 325°F (160°C) and grease a 9-inch springform pan.
2. Make the Crust: In a mixing bowl, combine graham cracker crumbs, melted butter, and granulated sugar. Press this mixture evenly into the bottom of the prepared pan.
3. Bake the Crust: Place the pan in the oven for 10-12 minutes until lightly browned. Remove from the oven and allow it to cool slightly.
4. Create Cheesecake Mixture: In a large mixing bowl, beat softened cream cheese with the granulated sugar and vanilla extract until smooth and creamy.
5. Incorporate Eggs: Add eggs one at a time to the cream cheese mixture, mixing thoroughly after each addition.
6. Add Sour Cream and Flour: Mix in the sour cream and flour until fully incorporated and smooth.
7. Pour Mixture into Pan: Pour the cheesecake filling into the cooled crust, spreading it evenly.
8. Bake the Cheesecake: Place in the oven and bake for 60 minutes or until the center is set but slightly jiggly.
9. Cool Gradually: Turn off the oven, leave the cheesecake inside for another hour. This helps prevent cracks.
10. Chill: After cooling, cover with plastic wrap and refrigerate for at least 2 hours or overnight for best results.
11. Prepare Berry Topping: Combine mixed berries, powdered sugar, and lemon juice in a bowl. Let macerate for 30 minutes before serving.
12. Combine and Serve: Once chilled, top your cheesecake with the berry mixture just before serving.

These steps will guide you in creating this incredible cheesecake with ease and flair.
