Preheat oven to 350 degrees F and prepare cupcake pans with paper cupcake liners
In a medium bowl, combine the flour, baking powder and salt; set aside
In the bowl of a stand mixer with paddle attachment, cream together the butter, vegetable oil and sugar until creamy and light in color ( approximately 2 minutes)
Add the eggs one at a time and vanilla extract and beat until fully combined and smooth
Alternate adding in the flour mixture and the milk until all ingredients are added in and the vanilla cupcake batter is smooth
Beat on medium speed for 3-4 minutes to make sure that all ingredients are incorporated
Evenly divide the batter into each cupcake pan filling ¾ full
Bake at 350 degrees F for 15-18 minutes or until the cake springs back at the touch
Allow the cupcakes to cool completely before icing with Raspberry Buttercream Frosting
