Creating your Red Velvet Cheesecake Halloween Treat is straightforward when you follow these steps:

1. Preheat Your Oven: Preheat the oven to 350°F (175°C). Grease and line a 9-inch springform pan with parchment paper.
2. Prepare the Red Velvet Batter: In a large bowl, sift together the flour, granulated sugar, baking powder, baking soda, salt, and cocoa powder.
3. Mix Wet Ingredients: In another bowl, whisk together the vegetable oil, buttermilk, eggs, red food coloring, vanilla extract, and white vinegar until well combined.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until smooth and lump-free.
5. Bake Red Velvet Layer: Pour the red velvet batter into the prepared springform pan. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean. Allow to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
6. Prepare Cheesecake Layer: While the red velvet layer cools, beat the softened cream cheese in a mixing bowl until smooth. Gradually add the sugar and vanilla extract, mixing until combined. Add the eggs one at a time, mixing until just incorporated.
7. Layer the Cheesecake: Once the red velvet layer has cooled completely, pour the cheesecake batter over the red velvet layer in the springform pan.
8. Bake Cheesecake: Return to the oven and bake for an additional 30-35 minutes or until the cheesecake is set but still slightly jiggly in the center. Turn off the oven and let the cheesecake cool inside with the door slightly ajar for an hour.
9. Chill: Remove the cheesecake from the oven and refrigerate for at least 4 hours or overnight for best results.
10. Decorate: Before serving, top with whipped cream and Halloween-themed sprinkles or edible decorations for a festive touch.
