Bake for about 19 minutes, or until a cake tester inserted comes out clean. Let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.

In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and powdered sugar on low, then gradually increase to medium-high. Beat for 3 minutes until smooth. Scrape down the sides, add cream cheese, and beat on medium-high for 1 minute until fluffy. Add vanilla and beat for 30 seconds.
