Grease and flour a 9-by-13-inch square pan or two 9-inch round pans or line with parchment paper. In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, nutmeg, and allspice or apple pie spice; set aside. Cream the butter with the brown and granulated sugars until light and fluffy. Beat in the eggs, one at a time, stopping between each addition to scrape the sides and bottom of the mixing bowl. Beat in vanilla, cider (or apple juice). Mix in the dry ingredients until evenly moistened. Fold in the apples and walnuts. Spread the batter in the prepared pan (s). Bake for 45 minutes for the sheet cake or 30-35 minutes for the layers or until a cake tester inserted in the center comes out clean. Remove the cake from the oven and set on a wire rack to cool completely. To make the frosting: In a small pan over medium heat, melt the butter. Stir in brown sugar and salt. Cook, stirring, until the sugar melts. Add the milk, bring to a boil, and pour into a mixing bowl. Cool for 10 minutes. Stir in confectioners’ sugar and vanilla. Beat well; if the mixture seems too thin, add more confectioners’ sugar. Use the frosting while it is still warm or it will firm up while it cools and you won’t be able to spread it.
