Hans & Gary,
This is the recipe I originally wanted to post last night but couldn't find it in my recipe archives until this morning. This was published in one of my wife's company newsletters several years ago. She's the office supervisor at the Pepsi distributor here in Wausau.
Pepsi-Cola Cake w/ Broiled Peanut Butter Frosting
2 cups flour
2 cups sugar
1 cup butter or margarine, melted
2 tbsp. unsweetened cocoa
1 cup Pepsi (or Coke), with fizz
1/2 cup buttermilk
2 eggs, beaten
1 tsp. baking soda
1 tsp. vanilla extract
1 1/2 cups miniature marshmallows
Cake instructions:
Preheat oven to 350 degrees. Grease and flour a metal 9x13x2 inch cake pan. Combine flour and sugar in a large bowl. Combine melted butter, cocoa, and cola and pour over flour and sugar mixture. Stir until well blended. Add buttermilk, beaten eggs, 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:
6 tbsp. butter
1 cup dark brown sugar
2/3 cup smooth peanut butter
1/4 cup milk
2/3 cup chopped peanuts
Frosting instructions:
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 8-10.
This cake and frosting are extremely sweet, so beware!
