Method
Making the Cake
Preheat your oven to 350°F (175°C). Grease your springform pan and line with parchment paper.
Whisk together the flour, sugar, baking soda, salt, and cocoa powder in a medium bowl.
Mix the vegetable oil, buttermilk, eggs, red food coloring, vanilla extract, and vinegar in a large bowl.
Combine the dry ingredients with the wet ingredients, mixing until just combined.
Pour the batter into the prepared pan and bake for 25-30 minutes. Let cool completely.
Beat cream cheese in a large bowl until smooth and creamy.
Add sugar and vanilla extract, mixing until combined.
Incorporate the eggs one at a time and mix until blended. If using, add sour cream and mix until smooth.
Layer the cheesecake mixture over the cooled red velvet cake and spread evenly.
Bake for 50-60 minutes until edges are set but center is slightly jiggly. Turn off oven and cool for 1 hour.
Cool to room temperature, then refrigerate for at least 4 hours or overnight.
Preparing the Frosting
Beat softened cream cheese and butter until smooth.
Gradually add powdered sugar and vanilla, mixing until combined.
If necessary, add milk a tablespoon at a time to reach desired consistency.
Frost chilled cheesecake if desired, then slice and serve.
Notes
Garnish with fresh berries or chocolate shavings for an elegant touch. Ensure all ingredients are at room temperature for better mixing.
