1In a saucepan, combine butter, vegetable oil, water, and white chocolate. Cook and stir until the butter and chocolate are fully melted and the mixture comes to a boil.
2Simmer the mixture for one minute.
3Combine all dry ingredients (flour, sugar, baking powder, baking soda, and salt) in a bowl and whisk to mix.
4Pour the hot mixture over the dry ingredients and stir gently until no lumps remain.
5Add milk, vinegar, vanilla bean paste, and large eggs to the batter. Mix gently until smooth.
6Pour the batter evenly between three 8-inch pans and bake.
7Once cooled, trim off the domes from the cake layers.
8Assemble the cake by layering the cake and cream cheese frosting, then finish with a final coat of frosting and piping on top.
