Creating your Heavenly Strawberry Cheesecake Bars is simple when you follow these steps:

1. Prepare the Crust: In a mixing bowl, combine graham cracker crumbs, melted butter, and sugar. Mix until well combined.
2. Press Crust: Press the mixture firmly into the bottom of a greased 9×13 inch baking dish to form an even layer.
3. Preheat Oven: Preheat your oven to 325°F (165°C).
4. Make Cheesecake Filling: In a large bowl, beat the softened cream cheese and sugar until smooth. Add vanilla extract and mix well.
5. Add Eggs: Incorporate the eggs one at a time, mixing until just combined. Avoid overmixing to prevent cracking.
6. Add Sour Cream: Gently fold in the sour cream until the mixture is smooth and creamy.
7. Pour Filling: Pour the cheesecake filling over the prepared crust, spreading it evenly.
8. Bake: Place in the preheated oven and bake for 30-35 minutes, or until the edges are set and the center is slightly jiggly.
9. Cool: Remove from the oven and allow to cool at room temperature. Then refrigerate for at least 4 hours, preferably overnight.
10. Prepare Strawberry Topping: If desired, mix the sliced strawberries with sugar and let them sit for 15 minutes to create a syrupy texture.
11. Top with Strawberries: Once the cheesecake is chilled, top with the sliced strawberries just before serving.
12. Slice and Serve: Cut into squares and serve chilled for the best taste and texture.

By following these steps, you will create a delicious dessert that will impress anyone who takes a bite!
