Step 1: Prepare the Crust
1. Preheat Oven: Preheat your oven to 325°F (160°C).
2. Mix Ingredients: In a medium bowl, combine the graham cracker crumbs, sugar, and melted butter. Mix until well combined.
3. Form the Crust: Press the mixture firmly into the bottom of a 9-inch springform pan to form an even layer.
4. Bake: Bake the crust for about 10 minutes, then remove from the oven and let it cool.

Step 2: Make the Cheesecake Filling
1. Beat Cream Cheese: In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy.
2. Add Sugar and Vanilla: Gradually add the sugar and vanilla extract, mixing until well combined.
3. Incorporate Eggs: Add the eggs one at a time, mixing on low speed until just combined. Do not overmix.
4. Add Sour Cream and Heavy Cream: Gently fold in the sour cream and heavy cream until the mixture is smooth.

Step 3: Bake the Cheesecake
1. Pour Filling: Pour the cheesecake filling over the cooled crust in the springform pan.
2. Bake: Bake in the preheated oven for 60-70 minutes, or until the edges are set and the center is slightly jiggly. The cheesecake will firm up as it cools.
3. Cool: Turn off the oven and leave the cheesecake inside with the door slightly ajar for about 1 hour to cool gradually. Then, remove from the oven and let it cool to room temperature.

Step 4: Chill
1. Refrigerate: Once cooled, cover the cheesecake with plastic wrap and refrigerate for at least 4 hours, or overnight for best results.

Step 5: Prepare the Strawberry Topping
1. Mix Strawberries: In a bowl, combine the sliced strawberries, sugar, and lemon juice. Let them sit for about 15-20 minutes to macerate and release their juices.

Step 6: Serve
1. Top Cheesecake: Once the cheesecake is chilled, remove it from the springform pan. Top with the macerated strawberries.
2. Garnish: Optionally, garnish with extra strawberries or whipped cream before serving.
3. Enjoy: Slice and enjoy your delicious Velvet Strawberry Cheesecake!
