minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely in the pan on a wire rack.
Prepare the Frosting: In a large bowl, beat the butter until creamy. Gradually add the powdered sugar, one cup at a time, beating well after each addition. Add the heavy cream, vanilla extract, and salt, and beat until the frosting is light and fluffy.
Frost the Cake: Once the cake is completely cool, spread the frosting evenly over the top. Cut into squares and serve.
