  • 1/2 cup vegetable oil
  • 2 teaspoons vanilla extract

For the Chocolate Pudding Filling:

  • 1 cup whole milk
  • 1/2 cup heavy cream

Instructions

  1. Preheat the oven: Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans and line the bottoms with parchment paper.

  3. Bake: Bake for 30–35 minutes until a toothpick inserted in the center comes out clean. Cool in pans, then transfer to wire racks.
  4. Make the pudding filling: Whisk together sugar, cornstarch, cocoa, and salt. Cook with milk and cream until thickened. Stir in chocolate and vanilla. Chill until thick.
  5. Prepare the frosting: Beat butter until creamy. Add powdered sugar, cocoa, cream, vanilla, and salt. Beat until fluffy.
