Cake: Preheat oven to 350 degrees. Grease and flour a 9x13x2-inch sheet cake pan. Combine flour and sugar in a large bowl. Combine melted butter, cocoa, and Pepsi and pour over flour and sugar mixture. Stir until well-blended. Add buttermilk, beaten eggs, soda, and vanilla. Mix well. Stir in marshmallows. Pour into prepared pan. Bake 40 minutes. Remove cake from oven and frost while still barely warm.
Frosting: Cream butter, sugar, and peanut butter. Beat in milk. Fold in nuts. Spread over cake. Place frosted cake under broiler about 4 inches from heat source. Broil just a few seconds, or until topping starts to bubble. WATCH CONSTANTLY AND BE CAREFUL NOT TO SCORCH FROSTING! Let cool at least 30 minutes before serving. Serves 8 to 10.
