Mountain Apple Cake

Preheat oven to 350 degrees F (175 degrees C). Sift together flour, salt, baking soda, and cinnamon; set aside. Grease and flour an 8 inch Bundt pan.

Whisk together eggs, oil, and 2 teaspoons vanilla extract until smooth.

Mix in sifted dry ingredients until moistened, then fold in sliced apples, pecans, and walnuts.

Pour batter into prepared Bundt pan.

Bake cake in preheated oven until golden brown on top, and a toothpick inserted in the center comes out clean, about 1 1/2 hours. Stir together brown sugar, milk, butter, and 1 teaspoon vanilla extract in a saucepan. Simmer for 2 minutes, then pour over cake in the Bundt pan as soon as it comes out of the oven. Allow cake to cool in pan set over a wire rack until it is room temperature, about 4 hours.

Whisk together mayonnaise, 1 teaspoon vanilla extract, and confectioners' sugar until smooth. Unmold cake and place onto a serving plate, spread icing over the top.
