Cocoa Cola Cake

In a large bowl, combine the first seven ingredients; beat on low speed for 30 seconds. Beat on medium for 2 minutes. Fold in marshmallows.

Pour into a greased 13-in. x 9-in. baking pan.

Bake at 350° for 35-40 minutes or until a toothpick inserted near the center comes out clean. Cool on a wire rack for 15 minutes.

Meanwhile, for frosting, combine cocoa and butter in a small saucepan. Cook over low heat until butter is melted. Stir in cola until blended. Bring to a boil, stirring constantly.

Remove from the heat; stir in confectioners' sugar until smooth. Fold in pecans.

Spread over cake.

Let stand for 20 minutes before cutting.
