Add eggs, one at a time, beating well after each addition. Add squash and maple flavoring; mix well. Combine flour, baking powder and baking soda; add to creamed mixture alternately with milk. Stir in walnuts. Pour into two greased and floured 9-in. round baking pans. Bake at 350 degrees F for 25-30 minutes or until a toothpick inserted near the center comes out clean. Cool 10 minutes before removing from pans to wire racks. For frosting, combine the brown sugar, egg whites, water, cream of tartar and salt in a heavy saucepan. With a portable mixer, beat on low speed for 1 minute. Continue beating over low heat until a thermometer reads 160 degrees F, about 8-10 minutes. Pour frosting into a large mixing bowl; add vanilla. Beat on high speed until stiff peaks form, about 3 minutes. Spread between layers and over top and sides of cake. Tips A stand mixer is recommended for beating the frosting after it reaches 160*.
