Chopped pecans (optional) 1 cup


  1. Preheat your oven to 350 degrees F (175 degrees C) and grease a 9×13 inch baking pan.
  2. Mix dry ingredients: In a large bowl, whisk together the flour, sugar, baking soda, and salt.
  3. Prepare the cola mixture: Melt the butter in a saucepan over medium heat. Stir in the cocoa powder and Coca Cola, bringing the mixture just to a boil.
  4. Combine mixtures: Pour the cola mixture over the dry ingredients and mix until well blended.
  5. Prepare the wet mixture: In a separate bowl, whisk together the buttermilk, eggs, and vanilla extract until smooth. Add this to the batter and stir until combined.
  6. Fold in marshmallows: Gently fold in the marshmallows and pour the batter into the prepared baking pan.
  7. Bake: Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
  8. Prepare the frosting: While the cake is baking, make the frosting by melting the butter in a saucepan, and stirring in the cocoa powder and Coca Cola. Bring to a boil, then remove from heat.
  9. Finish the frosting: Gradually whisk in the confectioners’ sugar and vanilla extract until the frosting is smooth. Stir in pecans if desired.
  10. Apply the frosting: Pour the frosting over the hot cake as soon as it comes out of the oven, smoothing it over the top.
  11. Cool and serve: Allow the cake to cool before serving. The frosting will set as it cools.
