Ingredients

Scale

For the Cake:

  • 2 ½ cups all-purpose flour
  • 1 ½ cups granulated sugar
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 1 cup vegetable oil
  • 1 cup buttermilk, at room temperature
  • 2 large eggs, at room temperature
  • 2 tablespoons unsweetened cocoa powder
  • 1 tablespoon vanilla extract
  • 1 tablespoon purple food coloring (gel or liquid)
  • 1 teaspoon white vinegar

For the Creamy Vanilla Frosting:

  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 24 tablespoons heavy cream

Instructions

  1. Preheat and prepare pans: Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to prevent sticking.
  2. Mix dry ingredients: In a medium bowl, whisk together the all-purpose flour and unsweetened cocoa powder until evenly combined.
  3. Cream butter and sugar: In a large mixing bowl, beat the softened butter and granulated sugar for about 3 minutes until light and fluffy. This step helps aerate the batter for a tender crumb.
  4. Add eggs and vanilla: Add eggs one at a time to the butter-sugar mixture, beating well after each addition. Stir in the vanilla extract for flavor.
  5. Add dry ingredients and buttermilk: Alternately add the flour mixture and buttermilk to the butter mixture, starting and ending with the flour. Mix gently until just combined to avoid overmixing.
  6. Add purple food coloring: Stir in the purple food coloring until the color is evenly distributed. Adjust the amount of food coloring if a more vibrant purple is desired.
  7. Incorporate vinegar and baking soda: In a small bowl, mix the white vinegar and baking soda — it will fizz. Quickly fold this mixture into the batter to provide extra leavening and lift.
  8. Bake the cakes: Divide the batter evenly between the two prepared cake pans. Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.
  9. Cool the cakes: Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely before frosting.
  10. Prepare the frosting: Beat the cream cheese and softened butter together in a large bowl until smooth and creamy.
  11. Add powdered sugar and vanilla: Gradually add the powdered sugar while beating until the frosting is fluffy. Stir in the vanilla extract and add 2-4 tablespoons heavy cream to reach desired consistency.
  12. Assemble the cake: Once cakes are completely cool, layer them with frosting between the layers. Cover the top and sides with the remaining frosting, smoothing or swirling as desired.
  13. Garnish and serve: Garnish the cake with purple sugar sprinkles, edible flowers, or a light dusting of cocoa powder for a decorative finish.

Notes

  • Ensure eggs and buttermilk are at room temperature for better mixing and texture.
  • Adjust food coloring quantity for preferred intensity of purple color.
  • Do not overmix batter to keep the cake tender.
  • Use a toothpick test to check for doneness to avoid overbaking.
  • Frost cake only when completely cooled to prevent frosting from melting.
  • For a dairy-free version, substitute butter and cream cheese with plant-based alternatives.
