This recipe was given to my mom from my aunt, Roberta June (Miller) Edwards.
2 C. Sifted All Purpose Flour
1/2 C. Buttermilk
3 T. Cocoa
2 Eggs, Beaten
2 C. Granulated Sugar
1 Tsp. Baking Soda
2 Sticks Butter, Melted
1 Tsp. Vanilla
1 C. Pepsi Cola
1 1/2 C. Miniature Marshmallows
Preheat oven to 350 degrees. Grease and flour a 9x13" pan. Mix flour, sugar & cocoa together in large bowl. Then beat in remaining ingredients except marshmallows, which should be folded in last. Pour into prepared pan and bake 40 minutes. Frost while still warm.
1/2 C. Butter, Softened
3 1/2 C. Powdered Sugar, Sifted
2 T. Cocoa
1/3 C. Pepsi Cola
Melt butter in a sauce pan over medium heat, stir in sugar, cocoa, and Pepsi, and bring to a boil. Remove from heat and pour over the cake. Let it cool before cutting.
My Variation: Cream butter and sugar, then beat in cocoa. Add Pepsi, peat until smooth. Add more powdered sugar if thicker frosting is desired.
