  Gradually add the dry ingredients to the wet ingredients, mixing with a rubber spatula after each addition until just combined. Divide the batter evenly between the prepared pans.

  Place the cake pans on grill grates. Close the lid and bake until a toothpick inserted into the center of a cake comes out clean, 30-40 minutes. Transfer the pans to a wire rack and let cool until the cakes are warm to the touch, then turn the cakes out of the pans onto the rack and let cool completely.

  Make the frosting: In a medium bowl, beat the butter and cream cheese together with an electric hand mixer until well combined. Beat in the vanilla, then gradually add the powdered sugar and beat on low speed until incorporated. Add the milk and beat on high speed, adding more milk 1 teaspoon at a time until the frosting is spreadable.

  Smear a dollop of frosting onto the center of a platter or cake stand. Set a layer of cake on top, then spread frosting over the top. Place the other cake layer on top, then spread the remaining frosting over the top and sides.
