In a separate large mixing bowl, cream together room temperature softened butter, vegetable oil, and sugar together for 3 minutes until fully combined. Texture will resemble a wet sand. You can do this with a whisk as long as your butter is soft enough or an electric mixer.
In a measuring cup or bowl, mix together the milk, sour cream, and vanilla extract. Pour into the batter, whisking until combined. Add in the dry ingredient mixture and mix together until just combined. Avoid overmixing. Lastly, fold in the sprinkles.
Fill the cupcake liners ¾ of the way full. Bake for 18 minutes or until a toothpick comes out clean.
After cupcakes are baked, allow them to cool in the pan for 5 minutes before removing to a cooling rack to cool completely. It's very important the cupcakes are cooled before frosting them.
To frost the cupcakes, you can simply use an offset spatula or butter knife to ice the cupcakes or you can pipe a buttercream swirl. Using the finished buttercream, fill a 16" piping bag fitted with a medium/large size open or closed star piping tip. Frost the cupcakes by taking the tip of the piping tip starting at the outside of the cupcake and swirling into a circle applying even pressure and slowly working upwards into smaller circles on top of each other.
Top with extra sprinkles and enjoy!
