4 ounces regular or light cream cheese

Instructions
Cupcakes:
Pre-heat oven to 350 degrees
Line a cupcake pan with cupcake liners or grease the cups with butter or non-stick cooking spray; set aside
In a medium bowl, whisk together flour, cornstarch, baking powder and salt; set aside
In the large bowl of an electric mixer, beat the sugar, eggs and vanilla on high speed for about 3 minutes or until mixture is well combined and thick
Add butter and oil and beat on high until well combined; scrape sides of the bowl with a spatula and mix for another minute
Reduce the speed to low and add ⅓ of the dry ingredients and then ½ milk; add another ⅓ of dry ingredients and remaining milk; add remaining dry ingredients and remove from mixer immediately
Use a spatula to incorporate any dry ingredients that have are not fully combined; distribute batter evenly among cupcake cups with a ladle or ice cream scoop
Bake in center of oven for 12-16 minutes or until a toothpick comes out clean
Allow cupcakes to cool for several minutes and then remove from tin and place on cooling rack; set aside and prepare buttercream
Buttercream:
Beat butter and cream cheese in the bowl of an electric mixer with the paddle attachment on high speed for several minutes until butter is light and creamy
Add 1 cup of powdered sugar and mix on low speed until combined; add remaining powdered sugar and vanilla and increase speed of mixer to high and beat until frosting is light and fluffy
