Creating your own Purple Velvet Cake can be straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

3. Combine Wet Ingredients: In a large mixing bowl, mix the sugar and oil. Add in the buttermilk and beat in the eggs, one at a time. Include the vanilla extract and purple food coloring, mixing until well combined.

4. Combine Mixtures: Gradually add the dry mixture to the wet mixture, gently stirring until just combined and smooth. Don’t overmix.

5. Add Vinegar: Stir in the vinegar, which helps create a tender crumb.

6. Divide Batter: Pour the batter evenly into the prepared cake pans.

7. Bake: Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center of the cakes comes out clean.

8. Cool: Let the cakes cool in the pans for 10 minutes, then remove them from the pans and place them on wire racks to cool completely.

9. Prepare Frosting: While the cake cools, in a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar, alternating with heavy cream, and mix until light and fluffy. Incorporate vanilla and food coloring as desired.

10. Assemble the Cake: Once the cakes are completely cool, place one layer on a serving platter. Spread a layer of frosting on top, then add the second layer. Frost the sides and top of the cake until fully covered.
