Instructions: To make the cake: Preheat the oven to 350 degrees. Butter and flour a 12-by-14-by-2 inch sheet pan.

Sift the flour and sugar into a large mixing bowl.

In a saucepan, heat the butter, cocoa and Coca-Cola until the mixture boils.

Pour this over the flour and sugar mixture, then mix thoroughly. Add the buttermilk, eggs, baking soda, vanilla and marshmallows; mix well. The batter will be thin and the marshmallows will come to the top.

Pour into prepared pan. Bake 30 to 35 minutes.

To make the icing: In a medium bowl, pour melted butter, cocoa and Coca-Cola over powdered sugar and mix well. Add pecans. Pour over the cake while the cake is still warm.

Note: Use real butter or stick margarine thats at least 80 percent fat. Do not substitute reduced-fat spreads; their higher water content often yields less-satisfactory results.

Note: To toast nuts, spread on baking sheet and bake in 375-degree oven for 5 to 8 minutes or until brown.
