Coca-Cola Cake

Ingredients for the Cake:
· 1 cup Coca-Cola
· ½ cup buttermilk
· 1 cup butter, softened
· 1 ¾ cups granulated sugar
· 2 large eggs
· 2 teaspoons vanilla extract
· 2 cups all-purpose flour
· ¼ cup unsweetened cocoa
· 1 teaspoon baking soda
· 1 ½ cups miniature marshmallows

Ingredients for Frosting:
· ½ cup butter
· 1/3 cup Coca-Cola
· 3 Tablespoons unsweetened cocoa
· 1 pound powdered sugar
· 1 tablespoon vanilla extract
· ¾ cup chopped pecans (optional)

Directions:
1. Preheat oven to 350 degrees. Grease and flour a 9x13-inch baking pan.
2. Stir together Coca-Cola and buttermilk in a small bowl; set aside.
3. Beat butter in a large bowl at low speed with an electric mixer until creamy. Gradually add sugar; beat until blended. Add eggs, one at a time, beating only until yellow disappears into the batter. Beat in vanilla.
4. Whisk together flour, cocoa, and baking soda in medium bowl. Add to butter mixture in thirds, alternating with half of Coca-Cola/buttermilk; beginning and ending with flour mixture. Beat at low speed only until blended. Fold in marshmallows.
5. Pour batter into prepared pan. Bake for 30 to 35 minutes or until a wooden pick inserted in center comes out clean. Cool 10 minutes. Meanwhile, make the frosting.
6. To prepare frosting, bring butter, cola and cocoa to a boil in a large saucepan over medium heat, stirring until butter melts. Remove from heat; whisk in powdered sugar and vanilla. Pour immediately over warm cake, spreading evenly. Sprinkle with pecans, if using. Cool completely.
