Step 1: Make the Strawberry Cheesecake Layer

1. Preheat the Oven: Preheat your oven to 325°F (163°C). Grease the springform pan and line the bottom with parchment paper.
2. Prepare the Cheesecake Batter:
   • In a large mixing bowl, beat the softened cream cheese until smooth and creamy.
   • Add the sugar and continue to beat until fully combined.
   • Mix in the eggs one at a time, followed by the vanilla extract and strawberry puree.
   • Pour the cheesecake batter into the prepared springform pan.
3. Bake the Cheesecake:
   • Bake for 40-45 minutes, or until the center is just set and slightly jiggly.
   • Turn off the oven and leave the cheesecake in the oven with the door slightly ajar for 1 hour to cool gradually.
   • Remove from the oven and refrigerate for at least 4 hours or overnight.

Step 2: Make the Red Velvet Cake Layers

1. Preheat the Oven: Preheat your oven to 350°F (177°C). Grease and line two 9-inch round cake pans with parchment paper.
2. Mix the Dry Ingredients: In a bowl, sift together flour, cocoa powder, baking soda, and salt. Set aside.
3. Combine the Wet Ingredients:
   • In a separate large bowl, beat together the sugar and vegetable oil until well combined.
   • Add the eggs one at a time, followed by the vanilla extract and red food coloring.
   • Mix in the buttermilk and white vinegar.
4. Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the wet mixture, mixing until just combined.
5. Bake the Red Velvet Layers:
   • Divide the batter evenly between the two prepared cake pans.
   • Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
   • Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.

Step 3: Prepare the Cream Cheese Frosting

1. Beat the Cream Cheese and Butter: In a mixing bowl, beat the softened cream cheese and butter until smooth and creamy.
2. Add Powdered Sugar and Vanilla: Gradually add the powdered sugar and vanilla extract, beating until fluffy and spreadable.

Step 4: Assemble the Red Velvet Strawberry Cheesecake

1. Layer the Cakes and Cheesecake:
   • Place one red velvet layer on a serving plate and spread a thin layer of cream cheese frosting on top.
   • Carefully place the chilled strawberry cheesecake layer on top of the first cake layer.
   • Add another thin layer of frosting on top of the cheesecake, then place the second red velvet layer on top.
2. Frost the Cake:
   • Apply a crumb coat of frosting and refrigerate for 30 minutes to set.
   • Frost the entire cake with the remaining cream cheese frosting, smoothing it out with an offset spatula.

Step 5: Garnish and Serve

• Decorate the cake with halved fresh strawberries and optional white chocolate shavings for an elegant touch.
• Refrigerate the cake until ready to serve for the best texture and flavor.
