I believe this cake falls under the catagory of "decadent." Just the fact that it has three layers makes it special in my book. I'm not fond of two-layer cakes--they look so skimpy. This cake has some interesting ingredients you're sure to love!

Separate eggs. Allow egg yolks and egg whites to stand at room temperature for 30 minutes. In a medium bowl stir together flour and baking powder; set aside.
In a large mixing bowl beat egg yolks, sugar, and coffee with an electric mixer on low until combined. Beat on high about 5 minutes or until satin smooth. Add flour mixture and beat until combined; stir in nuts. Set aside.
Thoroughly wash beaters. In a very large mixing bowl beat egg whites on medium until stiff peaks form. Gradually fold batter into beaten egg whites until combined. Pour into three 9x1-1/2-inch baking pans which have been greased and lined with waxed paper (also greased).
Bake in a preheated 350-degree oven for 20 to 25 minutes or until cake tops spring back when lightly touched. Cool cake layers on wire racks for 10 minutes. Remove cake layers from pans; remove waxed paper. Cool thoroughly on wire racks.
Spread 1/2 cup Creamy Butter Frosting on each layer; stack layers. Frost sides and top of cake with remaining frosting. If desired, garnish with chopped nuts. Loosely cover and chill cake for up to 3 days.
CREAMY BUTTER FROSTING: In a small saucepan whisk milk into cornstarch. Cook and stir over medium heat until thickened and bubbly. Reduce heat; cook and stir for 2 minutes more. Stir in rum or rum extract. Cover surface with plastic wrap. Cool to room temperature (do not stir).
In a large mixing bowl beat softened butter for 30 seconds. Add 2 cups powdered sugar; unsweetened cocoa powder and vanilla. Beat with electric mixer on medium until light and fluffy. Add cooled milk mixture to butter mixture, half at a time, beating on low after each addition until smooth. Beat in 5 to 6 cups additional powdered sugar until spreading consistency. Garnish with chopped walnuts or pecans if desired. Makes about 3-1/4 cups.
